Keywords

💡Whoosh Bottle

A whoosh bottle is a simple science experiment that demonstrates the principles of combustion and gas expansion. It involves igniting a flammable vapor within a container, which results in a jet of fire and a loud whooshing sound. In the video, Ryan and Mark create a whoosh bottle using rubbing alcohol in a five-gallon jug, which is a safe and controlled way to observe the rapid combustion of the alcohol vapors.

💡Combustion

Combustion is a chemical reaction that occurs between a fuel and an oxidizer, usually accompanied by the production of heat and light. In the context of the video, combustion is the process that happens when the vaporized rubbing alcohol mixes with oxygen in the air and is ignited by a butane lighter, producing the fire and sound effect of the whoosh bottle.

💡Rubbing Alcohol

Rubbing alcohol, also known as isopropyl alcohol, is a colorless liquid that is highly flammable and commonly used as a disinfectant. In the video, rubbing alcohol is used as the fuel for the whoosh bottle experiment because of its ability to vaporize easily at room temperature, filling the container with flammable vapor.

💡Vaporization

Vaporization is the process by which a substance changes from a liquid to a gas. In the script, rubbing alcohol vaporizes rapidly at room temperature, which is crucial for the whoosh bottle experiment as it creates a gas that can mix with oxygen and ignite to produce the whoosh effect.

💡Gas Expansion

Gas expansion refers to the increase in volume of a gas when it is heated. In the video, when the rubbing alcohol vapor ignites, it produces hot gases that expand rapidly. This expansion is what creates the pressure inside the jug, leading to the forceful release of gases and the loud whooshing sound.

💡Safety Equipment

Safety equipment mentioned in the video includes a fire extinguisher, apron or lab coat, goggles, and gloves. These are essential when conducting experiments involving fire and chemicals to protect the experimenters from potential hazards such as burns, spills, and chemical exposure.

💡Adult Supervision

Adult supervision is recommended in the video for the whoosh bottle experiment due to the involvement of fire and flammable substances. This ensures that the experiment is conducted safely and that any potential risks are managed by someone with more experience and knowledge.

💡Flammable Vapor

A flammable vapor is a gas that can ignite and burn in the presence of an ignition source, such as a flame. In the script, the vaporized rubbing alcohol creates a flammable vapor within the jug, which is then ignited to produce the whoosh bottle effect.

💡Oxygen

Oxygen is an essential reactant in combustion reactions. In the video, the oxygen in the air mixes with the vaporized rubbing alcohol to create a combustible mixture. The presence of oxygen is necessary for the combustion process to occur in the whoosh bottle.

💡Heat

Heat is the energy that initiates the combustion process in the whoosh bottle experiment. The heat from the butane lighter is what ignites the alcohol vapor, causing the rapid combustion that results in the whooshing sound and jet of fire.

💡Pressure

Pressure is the force applied per unit area and plays a significant role in the whoosh bottle experiment. As the gases produced by combustion expand rapidly, the pressure inside the jug increases. This high pressure forces the gases out through the small opening, creating the whoosh sound.

Transcripts

today on side guys whoosh bottles

welcome to side guys I'm Ryan and I'm

mark and on today's episode we'll be

making a whoosh bottle we get to play

with fire by your bad fire so goodbye

your bass when a flammable vapor is

ignited within a container with a small

opening the resulting expansion of gases

creates a jet of fire and a loud

whooshing sound the equipment you gonna

need this episode includes rubbing

alcohol five gallon jug a longneck

butane lighter measuring cup and for

safety a fire extinguisher because

sometimes this can happen we melted it

we did yeah the safety equipment for

this episode include apron or lab coat

to protect from spills and splashes as

well as goggles and gloves

we also recommend adult supervision as

we will be creating fire you should

perform the experiment in an outdoor or

well-ventilated area and be careful with

the jug as it's going to be hot

afterwards so let it cool down before

trying to move it the first step in our

experiment is to measure out about 25

milliliters of the rubbing alcohol into

our measuring cup we then want to pour

that in the five-gallon jug and give it

a few good turns to coat the inside with

the rubbing alcohol now we're ready to

go outside and light our fire with your

bottle coated light your butane lighter

and stick it in the top let's watch that

again in slow motion

let's look at this experiment a little

closer

a rubbing alcohol molecule looks like

this rubbing alcohol vaporizes extremely

easily which means it will rapidly

change state from a liquid to a gas at

room temperature in a liquid state

rubbing alcohol takes up much less space

than when it's a gas this means that a

very small amount of liquid rubbing

alcohol can vaporize to fill our entire

jug in our previous episode we talked

about combustion and Hell requires three

ingredients to occur fuel oxygen and

heat when alcohol vaporizes it mixes

with the oxygen in the air giving us two

of the three ingredients required for

combustion and creating a volatile

mixture of gases the only ingredient

missing for combustion to occur is heat

when we introduce heat in the form of

the flame from our butane lighter we are

adding the third ingredient to our

combustion triangle because the alcohol

fuel is in a gaseous state and is mixed

with lots of oxygen molecules combustion

will occur very rapidly the products of

this reaction are water vapour carbon

monoxide and carbon dioxide gases and a

balanced equation for this reaction

looks like this if you remember from our

episodes on the laws of gases when a gas

is heated it increases in volume and

pressure the rapidly expanding extremely

hot gases produced in this reaction try

and spread apart but because their

environment is confined the pressure

inside the jug quickly Rises the highly

pressurized hot gases inside our jug

want to be at equal pressure with the

outside environment to do so the gases

inside our jug are rapidly forced out

the jug small opening the rapidly xscape

in gases generates sound waves in the

air which can be heard as the loud jet

engine whoosh sound created in this

experiment well that's it for whoosh
