Dancing Rice Chemical Reaction Science Experiment
In this fun and easy science experiment, we’re going to explore and investigate endothermic chemical reactions and make rice dance.
Materials:
- Rice
- Baking soda
- Vinegar
- Clear cup, glass, or plastic container
- Spoon
- Water
Instructions:
-
Add a cup of water to the clear glass or container.
-
Add one teaspoon of baking soda to the water and stir.
-
Add some rice to the mixture. It should sink to the bottom.
-
Now add a tablespoon of vinegar to the mixture.
-
Observe what happens to the rice.
-
Feel free to add a drop or two of food coloring to the experiment for fun!

How it Works:
When baking soda and vinegar mix, an endothermic chemical reaction occurs. During this chemical reaction, carbon dioxide is released. As the carbon dioxide rises toward the surface of the cup, the bubbles attach to the sides of the grains of rice. The bubbles carry the rice to the surface of the water where the bubbles pop and the rice sinks back to the bottom of the cup.
Make This A Science Project:
Find a taller vessel like a 2-liter plastic bottle and see if the rice makes it to the surface. Does adding salt to the water effect the experiment. Adjust the measurements of vinegar and/or baking soda and observe if the rice behaves differently.
