Water
Plastic cup
Popcorn kernels
1 Teaspoon
1Tablespoon
Vinegar
Sodium Bicarbonate

What to do:

Fill a plastic cup until it is 3 quarters full.
Measure half a teaspoon of Sodium Bicarbonate.
Add the Sodium Bicarbonate to the water and then stir it until it dissolves.
Add 4 Popcorn kernels into the cup.
Add 1 Tablespoon of vinegar to the cup.
Watch closely for about 2 minutes.

What Happens?

The popcorn kernels will sit in the water for a bit and then the bubbles will attach to the kernels and will start floating to the top of the cup and then the bubbles will pop and then the kernels will fall back down to the bottom of the cup. This will happen over and over again.
