Canada Day Cool Chemical Reaction with Baking Soda & Water!

For something different in the sensory bin or sensory play department, give baking soda and water a try! When combined, they create a super cool (literally!) chemical reaction, forming a paste that is cold to the touch for long periods of time. I compare the consistency to toothpaste.

  • Baking soda (I use the extra large boxes and not the typical boxes for the fridge)
  • Water
  • Bin
  • Essential Oils (optional)
  • Goodies to throw into the bin


1- In the bin, combine baking soda and water. For one large box of baking soda, I use roughly 1 regular bottle of water. Start by adding a little bit and continue to add until you get the consistency of toothpaste. If you add too much water- add more baking soda (if you have). If you by accident add too much water and can’t even it out, I still think the soupy consistency is fun and so do kids! As you mix, you’ll notice the mixture get cold to the touch.

2- (Optional) Add essential oils and mix in. Peppermint is a neat addition since it already is the consistency of toothpaste. Why not make it more realistic?! My favourite peppermint right now is the Organic Peppermint Essential Oil from LucyLoo.

3- Add goodies to the bin.

  • Tongs (Mini red ones, I found at Walmart & Superstore)
  • Red & White jewels, bells, balls (Michaels & Superstore)
  • Silicone moulds (Superstore & Michaels)
  • Red Solo Cups (Dollar Stores & Party City)
  • Various scoops & Mini Mixers (Michaels, Homesense, Superstore)
  • Various cups & Bowls (Superstore)

4- Play Away!
