Q & A

What are some of the projects mentioned in the script that the speaker has been working on?

The speaker mentions working on cold fire, rainbow gecko tape, a frosting robot, microfluidic flow cells, a maglev laser table, and a hobby of making titanium chopsticks.

Why does the speaker find making titanium chopsticks a relaxing hobby?

The speaker finds making titanium chopsticks relaxing because it is not only a creative process but also provides a moment of Zen, especially with the new metal lathe.

What is the cost-effectiveness of making titanium chopsticks according to the script?

The speaker states that titanium is not very expensive, costing around 50 dollars for enough material to make seven or more pairs of chopsticks, which is a great value considering some people sell them for a hundred dollars or more a pair on Etsy.

What is the importance of maintaining precision when making multiple pairs of chopsticks?

Maintaining precision is important to ensure that the chopsticks match in terms of size, shape, and design, which presents a greater challenge when making more than one pair.

What is the role of a live center in the process of making titanium chopsticks?

A live center is used for tailstock support to prevent the titanium, which is a very bendy metal, from flexing while carving the pointy end of the chopsticks.

How does the speaker ensure a smooth and even surface finish when cutting the chopsticks?

The speaker suggests slowing down the cutting process, especially for the last pass, to maintain an even speed and achieve a better surface finish.

What is the significance of adding grooves to the chopsticks for extra grip?

Adding grooves provides extra grip to the chopsticks, as titanium can be slippery, preventing the Raman (chopsticks) from being dropped.

How does the speaker ensure that the two chopsticks are identical in their design and measurements?

The speaker uses a pair of calipers to regularly take measurements and make sure that the tapers, grooves, and lengths are the same for both chopsticks.

What is the science behind the vibrant colors that appear on the surface of the titanium chopsticks?

The colors are a result of thin-film optics, where a thin layer of titanium dioxide forms on the surface. The thickness of this layer, comparable to the wavelength of visible light, causes light to interfere with itself, creating the vibrant colors.

What are the two methods mentioned in the script for achieving the colors on titanium chopsticks?

The two methods mentioned are using a blowtorch and electrolysis. Both methods involve the formation of a thin layer of titanium dioxide, but they differ in their application and control over the color formation.

How does the electrolysis method for coloring titanium chopsticks work?

In the electrolysis method, a piece of titanium is connected to the anode and another piece to the cathode, both placed in an electrolyte solution. As voltage is increased, an oxide layer forms and grows until it reaches a thickness that causes interference of light, resulting in the appearance of colors.

What is the advantage of using electrolysis over the flame method for coloring titanium chopsticks?

The electrolysis method allows for more controlled color formation, as once a desired color is achieved, the voltage can be kept constant to replicate the same color on multiple pieces. It also avoids the risk of burning fingerprints into the pattern.

How does the speaker ensure the permanence of the colors on the titanium chopsticks?

The speaker mentions that the titanium oxide is an incredibly hard material and is very attached to the surface, making it quite permanent unless intentionally scratched.

What is the final step in the process of making the titanium chopsticks before coloring them?

The final step before coloring is sanding the chopsticks to break any sharp edges and to remove scratches, which also helps in achieving better color results.

Transcripts

over the last couple of months we've

done a lot of really hard science we

made real cold fire rainbow gecko tape a

frosting robot microfluidic flow cells

and a maglev laser table and later this

month I've got some even harder projects

I'm finishing up that I've been working

on for years frankly I needed a break so

this week is gonna be a bit different

and hopefully a little bit more relaxed

today we're gonna look at a hobby I used

to stay sane which is making titanium

chopsticks I've made a lot of artsy

things over the years and while wood was

my go-to material of choice ever since

we got the new metal lathe chopsticks

have become my moment of Zen I

especially love them because they're not

only stunning but they make for

incredible birthday presents for my

friends and Titanium really isn't that

expensive 50 bucks worth and you get

enough material to make seven or more

pairs of chopsticks and considering I've

seen people sell these for a hundred

bucks or more a pair on Etsy that's

great value it's also great machining

practice as anytime you've got to make

more than one of something the challenge

to maintain precision so that they match

is far greater so first I'm gonna take

you through the process of making these

and then we're gonna talk in depth about

how I get these incredible colors

there's actually a lot of surprisingly

interesting science that goes into how

those colors are formed which we'll talk

about later let's hop right in and get

started for all the work you'll see

today I'll be using a fresh half-inch

carbide insert steel can cut titanium

but carbide just makes this much easier

and I find gives a nicer finish if

you're careful after mounting some

titanium in my three jaw Chuck we're

gonna start with the facing cut for now

you don't need a lot of the titanium

sticking out an inch or so is plenty

titanium is a very bendy metal so when

we go to turn it we have to add a live

Center for tailstock support so that way

we can carve the pointy end of our

chopsticks without it flexing out of the

way after the facing cut I mounted my

drill chuck and Center drill in to the

tailstock this was used to make a small

divot that the live Center can seat into

with that done the titanium can be

extended much further out of the Chuck

and the live Center is added it's

important that you get everything

running as true is physically possible

before you start turning so if there's a

bit of wiggle when you turn on the lathe

stop adjust the tailstock and retighten

everything once you're happy with how

things are running we can set our

compound angle for my lathe this is done

with two bolts and I typically set the

indicator to either one or two degrees

for chopsticks two degrees goes faster

and is very usable but one degree

we'll give a longer more elegant taper

choose whatever you feel most of this

process is done by how you're feeling

about the piece so make it your own and

adjust however you want lock your angle

in and then we can start cutting cutting

titanium especially a piece this thin

and bendy is best done slowly I usually

take no more than 5,000 slowly develop

your taper when you're getting close to

having your whole taper established

you'll want to change how you take your

cuts normally for the first few I'm

pretty aggressive with how quickly I'm

moving the carriage back and forth to

take my cuts but that doesn't give a

very good surface finish for the last

pass you'll want to slow down how fast

you're moving everything and try and

maintain as even of a speed as possible

my lathe doesn't have power feed to cut

tapers so it takes a bit of practice to

do this by hand and get good results if

it's not perfect that's okay we'll be

sanding and adding other ornamentation

in a moment but the better this is the

less work you have to do later for this

particular pair I felt like adding a

little bit of extra grip as titanium can

be slippery and no one likes dropping

the Raman you'll want to reposition your

cutter to be pointing directly at the

metal so that it leaves nice triangular

impressions move the cutter to line up

with the end of the chopstick and then

set your dial on your horizontal control

wheel to zero so that you have a

reference then advance the wheel by some

increment here at Joe's five divisions

and take a light cut by plunging the

tool into the titanium slowly then back

out the tool move another five divisions

and repeat now because we need to make

two identical chopsticks we need to do

this whole same process to the other one

before we do anything else this makes it

so that our angle will be identical as

we haven't moved the compound and will

let us make any necessary adjustments to

the back ends afterwards it can be a bit

tricky to make things match so take your

time and use a pair of calipers to

regularly take measurements make sure

that your taper is the same length and

that the grooves line up properly and

then you have the same number of grooves

before we work on the back ends move the

chopsticks to be much further into the

chalk so it doesn't flop around and use

a file to round out the pointed end and

remove the divot we added earlier now

for the back ends we start by making

sure that the pair are the same length

when you order titanium they don't cut

them all will be perfectly the same

length so we need to make a few small

adjustments before we carve the rest of

the ornamentation on the back stay in

both chopsticks up on a piece of

mechanically flat metal there's lots of

parts on the lathe that fit this

description but use whatever you have

then figure out how much you need

to remove from one of the pair to make

them even with those adjustments done we

can go back to decorating I'm gonna

carve a little flower bud on the end but

you can use whatever you feel like round

them out carve rings it's art so there's

nothing mandatory at this point I

adjusted the compound angle to be 20

degrees and with just a small amount of

the end sticking out of the Chuck I

started taking passes I stopped when the

end wasn't a sharp point but still had a

small blunt tip remaining I adjusted the

angle of the tool to cut the right sort

of triangle to complete the lower part

of the bud shape and after lining up the

tool I just plunged it in slowly when

the shape was basically how I wanted it

I moved on to adding two more grooves

below this again I set my dial to zero

but this time I took a larger step of

about 20 divisions again the tools

plunged into the work to make a groove

this is repeated a second time to make a

second groove the same way at this point

all that's left is to use the file to

round out the edges and to make the ends

dome didn't get the shape I want repeat

this with the second chopstick and tada

you've got a beautiful pair almost ready

for color room the last step is sanding

because I chose to add this grippy

texture I need to go in with some folded

sandpaper and break all the little edges

so that it isn't sharp when you put it

in your mouth then just general sanding

on the rest of the piece to remove any

scratches and get it all looking shiny

and nice the better job of this you do

the better the colors will be in a

moment so be sure to take your time and

do a good job don't forget to turn the

piece around and get the back end as

well after that I rinsed the chopsticks

off camera and gave them a little wipe

with some isopropanol to remove any oils

that we contaminate the surface at this

point it's important not to touch the

metal as any oil from your hand will

either mess with the color formation or

burn a permanent version of your

fingerprint into the pattern which if

that happens you'll probably need to

resend everything and start the coloring

process again

so you'll notice I handle everything

with a paper towel to prevent that or

only grab areas I don't intend to add

color to now there's two ways to get the

colors that chemically do the same thing

but in two different ways they give

different looks fire and electricity

we're going to start with my preferred

method which is a blowtorch but we're

gonna come back to electricity in a

moment as it has a lot of advantages

over the fire method but also some

downsides it's really a dead simple

process and you just aim the torch at

the metal and let it rip you want to

keep the torch moving as heating one

area too fast will make the colors

appear too quickly and often you end up

overshooting the color you were aiming

for

the colors always appear in the same

order and we'll talk about why in a

second it starts with a light yellow

then gets more bronze than pinkish and

purple then vibrant blue once you hit

blue it'll start to lighten past that

point and eventually it'll hit a silvery

white if you keep going you can get

another round of colors but they're

usually muted comparatively so what's

happening here and why is titanium so

magically colorful all of a sudden well

we're really just growing a thin layer

of titanium dioxide which has

interesting optical properties titanium

isn't actually the only metal that will

do this and steel works as well by

growing a thin film of iron oxide on the

surface of steel it can also be made to

have a fantastic blue color though

titanium usually has more vibrant colors

and it's easier to get this to work the

reason this works is because of

something called thin-film optics with

both titanium and steel the powder form

of the oxides are just a solid opaque

color white for titanium or red or black

friar and respectively

but in these thin layers they're

actually reasonably transparent the thin

films that grow also happen to be just

about as thick as the wavelength of

visible light which gives rise to really

interesting optical effects to

understand this let's first think about

what happens when you shine a light beam

into water when the light changes

mediums that is goes from propagating in

air to propagating in water the beam is

bent at a specific slight angle this is

known as refraction and is why when you

put something like a chopstick in water

the bits sticking out of the water

doesn't line up with the image in the

water at the same time some of the light

doesn't actually enter the water at all

and it's just reflected off the surface

the other important thing to know is

that the amount that the light is bent

is also dependent on its color we can

see this when we shine a white light

through a prism and is wide light

spreads out into a rainbow different

colors are bent different amounts when

they're refracted through the same

material the same thing is happening

with the titanium dioxide films but with

the titanium the layer of super thin and

has the wonderfully reflective backing

of the titanium metal now when a light

beam hits the surface some will be

reflected immediately while some will

penetrate and be reflected off the

titanium this introduces a very slight

time delay between the light that's

reflected immediately and light that had

to go all the way through and back out

light has wave-like properties and as

such it can interfere with itself

picture this sort of like ripples in a

pond in areas where too

Ripple's overlap they can either get

bigger or smaller depending on how

they're lined up if two Peaks line up

you get a bigger peak for a moment

that's the sum of both if two valleys

line up you get a value that's deeper if

a peak and a valley line up you may get

Stillwater for a moment

you can actually see this happen with

light really easily and this was first

demonstrated with the classic double

slit experiment the idea is that when

you shine a light through a pair of thin

slits it behaves just like the pair of

ripples on a pond in areas where the two

waves add constructively together you

get a bright spot and in areas where

they add together destructively you get

darkness

this gives the characteristic

interference pattern of lines one

interesting thing to notice is just like

the refraction example this behavior

changes slightly by color so using

different colored lasers you can see

that as you move through the spectrum

towards blue the pattern compresses and

would continue to get smaller as you

approach UV light or if you use a white

light you get rainbow bands where red is

further out and blue is closer to the

middle for the same reason with our

layers of titanium that time delay

caused by the light having to go through

the titanium dioxide makes the light

behave in the same way as if there were

two beams interfering as the layer gets

thicker there's this sweet spot where a

particular color of light always happens

to bounce and add together to be

constructive while everything else adds

together to be destructive so to us this

looks like the metal being a specific

bright color this is actually the same

reason why soap bubbles and oil films

look iridescent sometimes and if you

want to see this for yourself all you

need is a tray of water and some thin

oil that will spread over the water

nicely

I found that bacon grease happens to

work especially well for this you want

nice soft light not direct light and a

small drop of oil on the tip of a skewer

or glass rod when you stand at the right

angle and touch the rod to the surface

of the water the oil will spread out and

for a moment that thin film effect is

obvious the colors are changing because

the thickness of the oil is changing as

it spreads out which adjusts how the

light is interfering with itself in this

case though the second reflection

happens at the boundary between the

water and oil instead of bouncing off

the titanium with bubbles it's the inner

and outer surface of the liquid that are

the two reflective layers in this case

so long as the layer is the right

thickness you can select for any

particular color you want which is

actually the basis for things like

dichroic mirrors that we've used in

previous videos so now that we know it's

the thickness of the oxide and

interference of light that controls the

color a more controlled way to do this

is to use electrolysis let's set up a

little electrolysis cell to see this in

action here

using a solution of sodium carbonate

also known as washing soda I didn't use

any particular amount and I literally

just threw some in the electrolyte

doesn't even really matter and this will

work with just about anything that I

would avoid things with chloride in them

not because it'll interfere but because

you run the risk of releasing a bit of

chlorine which is definitely not good

for you

hence the choice of sodium carbonate

I've prepared a piece of titanium by for

sanding and cleaning it and then

connecting it to the anode which is the

positive wire of my power supply I'm

using another scrap piece of titanium

for the cathode and both are simply

placed into the electrolyte solution

when we turn on the power very quickly a

layer of oxide will form on the titanium

but once that oxide layer forms it very

quickly stops growing as the layer

itself inhibits the reaction to grow a

thicker layer we need to increase the

voltage as we do this we're providing

more energy to the reaction to overcome

that passivating effect of the growing

layer once the layer gets thick enough

and the voltage is high enough we start

seeing colors form the nice thing with

this is that once you've dialed in a

color you like you can keep growing the

same color on piece after piece of

titanium by leaving the voltage

unchanged between runs this chart shows

a rough approximation of what color

you'll get at which voltages and it's

reasonably accurate but keep in mind

it'll vary based on the electrolyte you

choose and the concentration so you will

have to experiment a little bit but

let's walk through the whole spectrum as

with the flame method it starts yellow

at around 5 to 15 volts slowly getting

more bronze until you get purple at

around 25 volts by about 30 my power

supply maxed out but it's more than

sufficient to get a beautiful blue color

to get the higher voltages I'm using the

DC 2 DC voltage converter from my gel

electrophoresis setup it can't do low

voltages so it skips pretty quickly to

the second yellow as I continue to crank

the voltage we eventually get this

phenomenal red color and then as we pass

a hundred volts we eventually get a

really gorgeous purple and then finally

a dark green one thing that's really fun

is to crank the voltage really high and

then dunk the part and slowly pull it

out to get a rainbow effect it takes a

second for the oxide to grow so if you

remove part of the metal only the bit

that's still in the liquid will continue

to grow and if you're ever not happy

with the color you can always just sand

it off and try again

the best part is unlike a dye or a stain

or paint titanium dioxide is an

incredibly hard material and it's very

attached to the surface so it's quite

permanent unless you really go out of

your way to scratch it and at that point

you're scratching the metal itself all

in all no matter what technique you use

the end result is going to be a gorgeous

set of chopsticks which anyone would

love is a present

they require only the most basic tools

if you've already got a metal lathe and

are an especially good first project as

you will learn a lot to go with this set

I also whipped up a little chopstick

rest out of my favorite material Delrin

a few minutes with a file to give it a

flat bottom and the set was complete and

ready to be given to my friend so thanks

for coming on this journey through my

little hobby I know that was probably a

lot more information than you thought

you were going to get when you clicked

on the video but if you made it this far

thanks for sticking around and I hope

you enjoyed I'd planned on it being a

much shorter video but when it came time

to talk about how the titanium colors

worked I realized it was a much deeper

rabbit hole than I'd originally intended
