Procedural Writing

Inflating a balloon using yeast.
How did we do it?
Step 1.  You need to collect all the ingredients:
  * 3 teaspoons Yeast             * Cup of warm water             * 3 table spoons sugar
  *1 Balloon                           * plastic bottle
Mix all the ingredients in the plastic bottle.  Put the balloon on the neck of the bottle and place in the sun.
Now watch and see what happens.  Try with different size bottles to see if the balloon inflates more or less.

Ahh!, thats hot.

That yeast looks very grainy.

Lets make a paper funnel to help us.

Carefully as you go.
