    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!

    • @TheSciGuys

      +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.

  • @paulchamplin6458
    @paulchamplin6458 7 років тому +5

    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.
