Rainbow Eruption

I have 2 very active and growing boys.  Reed will be 10 next month and Jack 8 in August. When they were younger, I’m thinking 3, 4, 5 and 6 years old, I set up a lot of fun science-y type activities for them.  We used to sit around the kitchen table and do them together.  They still ask to do those types of activities from time-to-time.  Usually on a rainy day when I’ve taken away the PS4 and they’ve had enough of playing mini-sticks!

One of their favourite (yes, that’s how we Canadian’s spell it!) activities was always the ever popular “Rainbow Eruption!” Click for more fun Science activities and experiments.

  • a thick cookie sheet or a deep baking dish (to hold the mess)
  • clear glasses-the amount is up to you (Mason jars and baby food jars also work)
  • baking soda
  • food colouring
  • vinegar



Line the glasses up side by side and add 2 TBSPs of baking soda to each glass.
Then, add 5 or 6 drops of food colouring to each glass (1 colour per glass).

Finally, in a quick fashion, fill each jar with vinegar and watch the rainbow eruption appear before your eyes!

This is also a great experiment to do outside where you don’t have to worry as much about the mess!

My boys had so many laughs and so much fun doing this one!  They would just keep on adding more and more baking soda and vinegar to the jars-eruption after eruption.  Also mixing the colours together until the supplies were all gone!!  Good thing they’re all pretty cheap to buy.  Nothing like spending $5 for an hour of fun!

What are some of your family’s favourite Science activities to do together?
