-There are no hazardous materials involved in the experiment, but the video recommends using gloves, goggles, and an apron or lab coat to protect from spills and splashes.
What equipment and ingredients are needed for the experiment?
-The equipment and ingredients needed include multiple bottles (glass or plastic), sugar, yeast, balloons, a funnel, measuring utensils, and warm water.
How much yeast is used in the experiment?
-The experiment uses one package or 2 and 1/4 teaspoons of yeast per bottle.
How does the amount of sugar added to the bottles vary?
-The amount of sugar varies from no sugar in the first bottle, 1 teaspoon in the second, 2 teaspoons in the third, and 3 teaspoons in the fourth.
What is the purpose of the balloons in the experiment?
-The balloons are used to collect and visually demonstrate the carbon dioxide gas produced by the yeast as it ferments the sugar.
What happens to the balloons over the course of the experiment?
-Over the course of the experiment, the balloons gradually grow in size as they fill with carbon dioxide gas produced by the yeast.
Why does the balloon grow larger with more sugar in the bottle?
-The balloon grows larger with more sugar because there is more food for the yeast to consume, resulting in more carbon dioxide gas production and increased pressure inside the bottle and balloon.
What is the role of yeast in the fermentation process?
-Yeast plays a crucial role in fermentation by consuming sugars and starches, breaking them down to produce energy, and releasing carbon dioxide gas and ethanol as waste products.
What is the chemical reaction equation for the fermentation process described in the video?
-The chemical reaction equation is not explicitly provided in the transcript, but it generally involves the breakdown of sucrose (sugar) by yeast to produce ethanol and carbon dioxide.
How can viewers support the creators of the video?
-Viewers can support the creators by becoming a patron on Patreon, as mentioned in the video.
What should viewers do if they have questions related to the experiment?
-Viewers can ask questions in the comments section of the video or message the creators on Facebook, and they will try to help as best as possible.
Outlines
🌟 Fermentation with Sugar and Yeast
In this educational video, Ryan and Teresa explore the process of fermentation using sugar and yeast. They explain that fermentation is a chemical breakdown by microorganisms, typically resulting in gas and heat production. The experiment involves using bottles, sugar, yeast, balloons, a funnel, and warm water. Safety gear like gloves, goggles, and lab coats are recommended. The process starts by adding yeast and varying amounts of sugar to different bottles, followed by warm water. The bottles are then covered with balloons to observe the gas production over an hour. The video demonstrates that the more sugar present, the more carbon dioxide is produced, causing the balloons to inflate. The hosts also discuss the role of yeast in bread rising, explaining that yeast consumes sugar and produces carbon dioxide and ethanol as waste, which helps the bread to rise. The video concludes with a call to action for viewers to support their content, subscribe for future episodes, and engage with them on social media.

Highlights
Introduction to fermentation with sugar and yeast by S side guys.
Fermentation is a chemical breakdown by bacteria, yeast, or microorganisms, producing gases and heat.
Equipment needed includes bottles, sugar, yeast, balloons, a funnel, measuring utensils, and warm water.
Safety measures recommended: gloves, goggles, and an apron or lab coat.
Experiment involves adding yeast and varying amounts of sugar to bottles.
Yeast and sugar are added to bottles with no sugar in the first, and 1-3 teaspoons in subsequent bottles.
Each bottle is filled with 1 cup of warm water and mixed gently.
Balloons are placed on the bottle spouts to observe gas production.
Yeast is a fungus with about 160 known species, used for thousands of years in food production.
Yeast helps bread rise by consuming sugars and starches, producing carbon dioxide and ethanol.
Carbon dioxide gas causes balloons to inflate as it is produced by yeast metabolism.
Bottles with more sugar result in more carbon dioxide and larger balloons.
The chemical reaction equation for yeast metabolizing sugar is provided.
The experiment visually demonstrates the relationship between sugar, yeast, and gas production.

today on S side guys fermenting yeast
and
[Music]
[Music]
sugar welcome to S guys I'm Ryan and I'm
Teresa and today we're looking at
fermentation with sugar and yeast we'll
be producing gas and it won't be me this
time this is a viewer requested episode
thank you to this viewer for
recommending this episode fermentation
is a chemical breakdown of substances by
bacteria yeast or other microorganisms
usually involving the production of
gases and heat the equipment and
ingredients you're going to need for
this episode includes multiple bottles
they can be glass or
plastic sugar yeast balloons a funnel
measuring utensils and warm water we're
not working with anything hazardous in
this episode but we still recommend
gloves goggles and an apron or lab coat
to protect from spills and splashes the
first step in our experiment is to add
all your ingredients into the bottles
using a funnel add one package or 2 and
1/4 teaspoons of
yeast now we're going to add the sugar
in the first bottle we're not going to
add any sugar in the second bottle we're
going to add 1
teaspoon in the third bottle 2 teaspoons
and in the fourth bottle 3
teaspoons with all your dry ingredients
in the bottles add 1 1 cup of warm water
into each
bottle with all the ingredients in your
bottle cover your bottle with your thumb
or put the lid back on and give it a
gentle
mix with all the ingredients in the
bottle put one balloon on each bottle
spout and leave them somewhere warm to
sit for an
hour over the next hour or two the
balloons will gradually grow in
size after few hours you'll notice the
balloon that was covering the bottle
that had the most sugar in it grew to a
larger
size let's look at this experiment a
little closer yeast is a fungus and
there are about 160 known species of
yeast yeast is very small 1 G holds
around 25 million cells and has been
used for thousands of years to help
bread rise but how does a fungus help
bread rise it has to do with what yeast
eats how they metabolize that food and
what waste products are released yeast
feeds on sugars and starches when the
yeast consumes the sugar in our bottle
it breaks it down to be used as energy
but like all living beings waste
products are produced when metabolizing
food when the yeast metabolizes the
sugar the waste produced is carbon
dioxide gas and ethanol the carbon
dioxide gas floats out of the liquid
into the bottle producing Bubbles and
eventually floating up into the balloon
as the yeast consumes more sugar and
produces more carbon dioxide the
pressure inside the bottle and balloon
increases this pressure presses on the
walls of the balloon causing it to
expand and grow the equation for this
reaction looks like this the reactant
sugar sucrose is on the left and the
products ethanol and carbon dioxide are
on the right the bottles with greater
amounts of sugar have more food for the
yeast to consume which results in larger
amounts of carbon dioxide produced and a
larger balloon on the top of the bottle
