This project explores the chemical reaction between baking soda and vinegar, adding food coloring to create a fizzing rainbow. Students will learn about acid-base reactions and observe the effects of color mixing.
If I mix baking soda with vinegar, then it will create a fizzing reaction that can be enhanced with food coloring to display different colors.

Gather all materials on a tray.
Pour equal amounts of baking soda into each cup.
Add different colors of food coloring to each cup of baking soda.
Fill another set of cups with vinegar.
Slowly pour vinegar into the first cup of baking soda and observe.
Record the fizzing reaction and color change.
Repeat the pouring for each colored baking soda cup.
Compare and record the intensity of fizzing and colors.
Clean up the materials and tray after the experiment.
The vinegar will react with the baking soda to create a fizzing reaction. The addition of food coloring will display different colors, creating a visual effect of a fizzing rainbow.

Perform the experiment on a tray to catch spills. Do not ingest any substances.
Use clear cups for better viewing of the reaction.
Create a video of the experiment to show during the presentation.
Prepare a simple poster explaining the acid-base reaction.
Fizzing occurs due to the acid-base reaction between vinegar and baking soda, releasing carbon dioxide gas.
Yes, lemon juice or citric acid can also be used to observe similar reactions.
Yes, altering the amount of vinegar can change the intensity and duration of the fizzing reaction.
