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.

@jijikurian2348 5 лет назад

@paulchamplin6458 7 лет назад

To take this a little farther, you can carefully remove the balloons and slowly, carefully release the accumulated gas into a beaker. CO2 is relatively massive, so it settles into the beaker nicely. Have a similar beaker next to the one with the CO2 in it, and use a lighter, trying to keep it lit in the "empty" beaker (it stays lit), and then the CO2 filled beaker (it goes out). This also works for any CO2 producing experiments, like those using dry ice.

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

@TheSciGuys 8 лет назад

+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.
