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

Рет қаралды 946,940

8 жыл бұрын

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.

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!

Hi guys, I was wondering would light intensity affect blinking rate ? And if so why would it? Thank you

@TheSciGuys 8 жыл бұрын

+DiLLZGFX Yes, there is a reflex that causes your eyes to blink when too much light enters them, to prevent damage. That's why it's so hard to look at the sun, because you have to constantly fight to keep your eyes open, not that anyone should be doing that.
