Add all of the yeast packet and gently swirl the bottle a few seconds.
When yeast is cold or dry the micro organisms are resting.
By adding warm water the yeast dissolves, it becomes active it comes to life!
Dont bother looking for movement, yeast is a microscopic fungus organism.
Add the sugar and swirl it around some more.
Like people, yeast needs energy (food) to be active, so we will give it sugar.
The yeast is beginning to consume eat the sugar energy.
It also produces a gas called carbon dioxide.
With no place to go but up, this gas slowly fills the balloon.
A very similar process happens as bread rises.
Carbon dioxide from yeast fills thousands of balloonlike bubbles in the dough.

Try this experiment as explained above AND another one without the sugar.
Ask the kid what they think will be different as a result.
