#2 Inflate A Balloon On Its Own

For this you need an empty drinks bottle, a thin balloon, some yeast, sugar, and some water. Mix together 2 teaspoons of yeast with one teaspoon of sugar and a cup of water and add to the bottle. Fix the balloon over the top with an elastic band and watch it inflate. This works due to the yeast eating sugar and producing carbon dioxide.
