- Backing Soda
Mix Vinegar and backing soda in the beaker.
Put the popcorn inside the beaker.
The popcorn will start to move.
Dancing popcorn experiment works through a chemical reaction. The two chemicals react when mixed and form carbon dioxide (CO2) gas. The gas forms bubbles that collect around the popcorn kernels.
The gas bubbles lift the kernels up to the surface of the liquid, and when the gas is released, the kernels fall back down into the jar, making it look like the kernels are dancing or jumping!
