Fizzing Baking Soda Bats Experiment

I have done this baking soda and vinegar experiment before; this is just a variation of it. It’s always fun and goes down well with kids. I only thought to do this because I set up a potions class for BB for an afternoon activity and he was fascinated with the reaction he got from the baking soda and vinegar. As it had been a couple of years since I last did it, and the first time that BB could really join in we made fizzing baking soda bats.

Make sure you follow my Halloween board on Pinterest for more ideas. Don’t forget to save the pin for later.

To make your own fizzing baking soda bats you will need:

  • Baking soda
  • Bowl
  • Food colouring
  • Water
  • Spoon
  • Bat shaped ice tray*
  • Deep sided tray
  • Vinegar
  • Washing up liquid
  • Condiment bottle
  • Wooden spoon

* My bat ice tray is actually a Disney’s Haunted Mansion one I bought years ago. You can find normal bat shaped silicone ice trays on amazon.

Add about 3 tbsp. of baking soda to a bowl, add a little bit of food colouring, then add a teaspoon of water at time. You want to make a paste. I made 3 different coloured batches.

When it is at the right consistency fill up your moulds and pop it into the freezer over night. This is a great activity to prepare in advance and then take them out at a later date. I think it was about a week between me making them and BB playing with them.

When you are ready to use the fizzing baking soda bats, fill up the bottom of a deep-sided tray with some vinegar. Squirt some washing up liquid in to create the bubbles.   Then fill up some condiment bottles with vinegar. We used a whole bottle of vinegar.

Carefully take the bats out of the moulds and put them on a plate.

After putting the initial one in, BB literally emptied the whole plate into the tray in one go! It created quite the reaction. He then used the condiment bottles to add even more vinegar.

YC was rather sad to have missed it all, so I promised to make some just for her.

YC did enjoyed making the marbled effect though.
