Fill a small glass jar 3/4 full of water. Mix in 2 tablespoons of baking soda and mix well. Add a drop or two of food coloring and 10 to 15 popcorn kernels. Then add a few drops of vinegar. The kernels will start to move in one or two minutes.
When the vinegar is added to the baking soda solution, carbon dioxide bubbles are produced and they carry the popcorn seeds up to the top.

I feel like I should start a folder just to keep your cool ideas in for later. :) That is so neat!
