Fire Water Balloon - Coolest Conductor of Heat
Summary
TLDRIn this educational video, a fascinating experiment demonstrates the heat transfer properties of water. A water-filled balloon is cautiously placed into a flame, contrary to expectations, it doesn't burst. Instead, the water inside acts as a heat conductor, drawing heat away from the latex, preventing combustion. The balloon shows signs of charring but remains intact, illustrating the scientific concept in a visually striking way.

Q & A
What is the main focus of the experiment described in the script?
-The main focus of the experiment is to demonstrate the concept of heat transfer using water-filled balloons and how water acts as a great conductor of heat.
Why does the balloon not pop when placed over a flame?
-The balloon does not pop because the heat is being conducted away from the latex of the balloon and into the water, preventing the balloon from reaching its ignition point.
What safety precaution is mentioned in the script before performing the experiment?
-The safety precaution mentioned is to put on safety glasses before attempting the experiment.
What is the purpose of using clear balloons in the experiment?
-Clear balloons are used so that observers can see what is happening inside the balloon as the water heats up and the heat is conducted away.
What is the expected outcome if a regular balloon without water is placed in a fire?
-A regular balloon without water is expected to pop when placed in a fire due to the lack of heat conduction to prevent combustion.
What does the script suggest about the presence of soot on the bottom of the balloon?
-The presence of soot indicates that the balloon has been in contact with the flame, but the heat has been conducted away by the water, preventing the balloon from burning.
Why is there a burn mark on the bottom of the balloon?
-The burn mark is there because the water inside the balloon has not yet reached the area, and the heat is not being conducted away from that spot, allowing the soot to accumulate.
What happens when the water in the balloon starts to touch the sides?
-When the water touches the sides, the heat from the flame is conducted away by the water, preventing the balloon from burning at that point.
Why is it important to ensure that there are no 'superhuman balloons' in the experiment?
-This phrase is likely a playful way to emphasize the importance of ensuring that the balloons used are ordinary and not unusually resistant to heat, which could affect the outcome of the experiment.
What is the scientific principle behind the experiment that makes it 'cool'?
-The scientific principle behind the experiment is heat transfer, specifically how water, being a great conductor of heat, can pull heat away from the balloon and prevent it from bursting in the flame.
How does the experiment change the traditional way of demonstrating heat transfer with water in a bag?
-The experiment changes the traditional method by using water-filled balloons instead of a bag, which provides a more visually engaging and surprising way to demonstrate the principles of heat transfer.
Outlines
đ„ Fireproof Water Balloon Experiment
This paragraph describes an educational experiment demonstrating heat transfer using water balloons. The narrator explains that while a regular balloon would pop when exposed to fire, a water-filled balloon can be held over a flame without bursting. The heat is conducted away from the latex and into the water, preventing the balloon from burning. The experiment is visually demonstrated, with the narrator instructing a participant to place the water-filled balloon into the flame, showing that the balloon remains intact with only a soot mark left on the bottom, illustrating the effectiveness of water as a heat conductor.

long long time ago there was a a great
experiment where You' put water in a bag
and then you could actually boil the
water in the bag for kids and and it's
true we're talking about heat transfer
and the science of heat and it wasn't
all that impressive to kids so I just
changed it up a little bit and tried
water balloons okay so here watch what
happens if you take a regular balloon
and put it in the fire what's going to
happen Becky it's going to pop yeah put
your safety glasses on you're right so
it's going to pop let's just make sure
that we don't have superhuman balloons
here that see no problem right no
problem all right so now look at what we
do you now take a balloon I'm using
these clear ones so you can kind of see
what's going on and you can pick up the
one that you have over there since I
already tied it for you look at this I
put the water in the balloon like this
so there's not a lot that's
there all right so that's perfect so now
here watch this I want you to take the
balloon and now you're going to put it
right into the flame so you're going to
go down and put it into the flame get a
little little closer a little closer a
little closer you can actually start to
boil the water in the balloon K because
water is this great conductor of heat
and so it literally pulls the heat out
now turn to the camera and look at the
burn mark on the bottom you can see the
soot that's sitting down on the bottom
is an amazing so if you see this here
look at this it won't uh burn because
now all that heat is being pulled away
from the latex there the balloon and
transferred there to the water so when
you tip up like this there is that
little Mark that's there Co isn't
amazing so now here try it on the side
no it's okay just kind of go to the side
here like this if you get to the side
like that's where the water starts to
come in and and it's good that you have
this to back to I know I know so but
isn't that an amazing thing and it's
just about the the the the transfer
there of that heat and water is a great
great conductor of that very
cool
