how to blow up a balloon with yeast.

• A packet of yeast (available in the grocery store)
• A small, clean, clear, plastic soda bottle (16 oz. or smaller)
• 1 teaspoon of sugar
• Some warm water
• A small balloon

• 1. Fill the bottle up with about one inch of warm water.
  ( When yeast is cold or dry the micro organisms are resting.)
• 2. Add all of the yeast packet and gently swirl the bottle a few seconds.
  (As the yeast dissolves, it becomes active - it comes to life! Don't bother looking for movement, yeast is a microscopic fungus organism.) 
• 3. Add the sugar and swirl it around some more.
  Like people, yeast needs energy (food) to be active, so we will give it sugar. Now the yeast is "eating!"


• 4. Blow up the balloon a few times to stretch it out then place the neck of the balloon over the neck of the bottle.
• 5. Let the bottle sit in a warm place for about 20 minutes 
  If all goes well the balloon will begin to inflate!
