Science doesn’t have to be expensive, hard to find ingredients. It can be simple, and already in your kitchen like this hopping popcorn kernels science experiment. It’s perfect for the littler ones to help out with and do too.
Hopping Popcorn Kernels

All you need are the things you most likely have in your kitchen already. Like baking soda. Vinegar. Popcorn kernels. Water. A jar.
I admit, that if it weren’t for the fact that hubby had been begging for an air popcorn maker a few years ago, and the fact that we no longer have a microwave, we probably wouldn’t have had the popcorn kernels on hand.
The best things about this experiment is that you don’t have to worry about exact amounts. Just pour and dump.
- a clear glass container
- popping corn
- 2 cups of water
- 2 tbsp of baking soda
- 6 tbsp of white vinegar
- food coloring (optional)
Poor Austin tried to be very exact. Her first attempt did not work as planned. In fact, nothing happened. At all. We knew it worked though because it wasn’t our first attempt, Gauge and I had no problems.
How to get your hopping popcorn kernels hopping?
Add water to your jar so that it is about 3/4 full, and add a couple drops of food color if you so desire. Add your baking soda and stir well until it is all dissolved. Add a small handful of popping corn kernels.
Add the vinegar and watch the corn start to hop up and down! You don’t have to stir them, but you can. Gauge stir them a lot.
I had small bowls such as the green on you can see in the above picture with the ingredients that they each needed. It made it really for Gauge to do. One bowl for vinegar, another for baking soda.
Baking soda and vinegar react with each other because of an acid-base reaction. Baking soda is a bicarbonate and vinegar is an acetic acid. One of the products this reaction creates is carbon dioxide. Which is why the kernels are hopping around in there.
