5. Put the packet of dried yeast Add 1 cup very warm water
into the clear plastic bottle to the bottle so that the
bottle is about 1/4 filled
6. Add 5 teaspoons of sugar Place the balloon over the
to the bottle and swirl the mouth of the bottle so taht
bottle around it’s fully coverd and there
are no leaks
7. Place the bottle with the balloon on it on a warm
windowsill or place it into a large bowl of warm water
8. After several minutes, you’ll notice the balloon standing
upright. If you don’t see anything happen, keep waiting.
9. CONCLUSION:
A very similar process happens as
bread rises. Carbon dioxide from
yeast fills bubbles in the dough.
That gas makes the bread rise.
