WHAT’S THE  RAINBOW BAKING SODA SCIENCE

The science behind this fizzing, erupting rainbow activity is all about chemical reactions and states of matter!

When the acid (vinegar) and the base (baking soda) mix together, they form a gas called carbon dioxide. This gas is all the fizzing, bubbling action you can see, hear, and even feel if you put your hand close enough! Would lemon juice work, too?

All three states of matter are present: liquid (vinegar), solid (baking soda), and gas (carbon dioxide). When the liquid and solid combine, they form a gas.

You can continue to add vinegar and baking soda to keep the reaction going as much as you like. We had to work fast to get the whole rainbow fizzing simultaneously.

RAINBOW SCIENCE EXPERIMENT SUPPLIES

  • Vinegar
  • Baking Soda
  • Dish Soap {optional}
  • 12 Test Tubes
  • Test Tube Rack
  • Food Coloring
  • Spoon  and Measuring Cup

ERUPTING RAINBOW SCIENCE EXPERIMENT SET UP

STEP 1: Mix up small containers with rainbow colors by adding food coloring to vinegar to each! We set up two rows of 6 test tubes and filled one row with vinegar. Practice color mixing by adding food coloring to the vinegar. STEP 2: Add a couple of spoonfuls of baking soda to the other row of test tubes. If you don’t have test tubes, you can use mini water bottles, clear plastic cups, or small vases. See our homemade lava lamps with plastic cups! You want to use something narrow enough to force the chemical reaction up and out for the eruption effect. If you use a wider top vessel, the gas will have more room to spread out before it spreads up! You must also consider adding more baking soda to a larger container. STEP 3: Lastly, add a couple of drops of dish soap to each test tube containing baking soda. STEP 4: Now for the fun part, mixing! Once you have explored the original rainbow science reaction experiment, my son was thrilled to go ahead and mix colors together and add more baking soda. Science can be really fun!

I might just be waiting for Spring, but I love rainbows. With the 19″ of snow we got yesterday, I figured what better time than to share an erupting rainbow science experiment with you. So pretty and easy to do with kids, you can check out simple kids science in so many different ways.

AWESOME RAINBOW SCIENCE

This isn’t the first time we have enjoyed rainbow themed science! Look at all the fun but simple ways to explore beautiful colors while incorporating great science ideas. Slimes, crystals, LEGO, and more! We have tons of science projects to choose from.

My son has been really into our test tube science experiments, but you can use any clear jar or cup whether it’s mixing potions or dissolving candy. Adding a few science-themed items and tools can bring out the junior scientist with little expense.
