Science Experiment For Kids
Here is how you make your own fizzing rainbow science experiment. It’s very similar to the Baking Soda Volcano Experiment.
Fizzing Rainbow Science Experiment For Kids Set-Up
Make a paste from baking soda and water. Divide the paste into five bowls and dye each cup a color of the rainbow with food coloring.
Doing the Fizzing Rainbow Science Experiment
Roll the colored baking soda paste into rolls and arrange them into a rainbow on the tray or plate. This works best if you start with blue and complete the rainbow backwards, arranging the colors in teh following order:
Once the rainbow is complete, use the pipettes to pick up a small amount of vinegar.
Squirt the vinegar onto the rainbow and watch it fizz!
Repeat the process until the rainbow no longer fizzes or the tray is filled with colored liquid.
Discuss the science of baking soda and vinegar reactions as the kids complete the activity.
Why does the rainbow fizz?
What makes it stop fizzing?
I hope you enjoyed the baking soda fizzing rainbow colors science experiment for kids.
