Fermentation of Yeast & Sugar - The Sci Guys: Science at Home

Welcome to science at home in this experiment we are exploring the fermentation between yeast and sugar. Yeast uses sugar as energy and releases carbon dioxide and ethanol as waste. Yeast and fermentation have been used for thousands of years when making bread. At the end of this episode you will be able to demonstrate fermentation, explain why yeast and fermentation make a balloon grow and explain the chemical reaction that occurs during fermentation.

Equipment and Ingredients:
Water
Yeast
Sugar
Balloons
Bottles

Probably the most awkward video I've ever watched at 12 at midnight

[dearanonixyhylo]

when COVID19 is taking over the world and now you have to do a lab on youtube because you can't even shop for balloons

his joke at the beginning really bothers me

This guy is the human embodiment for whatever directors of kids films think makes a kids film good.

After a carefull analysis my conclusions is

Them: 1:41 put the lid back on the bottle
Also them: Shake the bottle without covering it

I have been fermenting 2 cups of sugar with one package of dried yeast in a half gallon of water for two weeks and refrigerating the product to settle the yeast for a week. I mix it with Bloody Mary or whiskey sour mix and I have a pretty nice drink. Actually, I drink it straight sometimes. I am 90 years old and it has not killed me yet!

Thank you for this video. It was perfect for the prelab in my 6th graders science class.

karan karan karan
never gonna give you up

[ArchismitaSamanta]

Thanks finally got something interesting to do for my biology project

[DoggieBreath]

No big deal, but the chemical formula in the video for sucrose is incorrect; the formula is actually for glucose. Sucrose is C12H22O11.

This video makes me both wanna cry myself to sleep and cry myself to sleep at the same time

Sir I tried this experiment at home and it was successful and thanks a lot for teaching

How does the bubbles of the yeast smell? Asking for a work sheet activity
