When we spot a rainbow in the sky, my kids go wild! So when I told them that we were going to create our very own rainbow, they were jumping up and down ready to go! This Erupting Rainbow Science Experiment is perfect for little kids as well as big ones, and the best part? It’s a super easy activity to put together – In fact, you probably already have everything you need to get started!
Begin by gathering your supplies:
- baking soda
- food coloring
- an ice cube tray or two (I found mine at Wal-Mart)
- a couple of cups to use for pouring
- a plastic bin to contain the mess (optional)
We got started by letting the boys put a smidge (probably about a tablespoon to be more exact) of baking soda down in each section of their ice cube tray.
Next, I added a drop of food coloring to each section –
no particular order or anything, I just randomly made colorful drops.
Now…for the erupting rainbow part…I let each child pour cups full of vinegar all over their ice cube tray,
and each section fizzed up with colors everywhere!
Around here, I always keep an extra-large bag of baking soda (from Sam’s) and an extra-large jug of vinegar (from Target) on hand. Not only are these ingredients great for science experiments, but I also use a mixture of the two in my laundry as well as when I’m cleaning in the kitchen.
In the fall, we have loved doing this same type of experiment – inside of a pumpkin! Yes! Check out this Erupting Pumpkin Science Experiment – another activity that is perfect for all ages!
Warning: The Dad in your family may get REALLY excited about this one!
