The other day when we were learning about primary and secondary colors and having a grand time with our colored ice cubes I got busy cleaning our kitchen afterwards. I saw that I had a box of baking soda out still from our volcano in a bottle activity and wondered to myself if you could freeze vinegar? Combining these two activities of freezing liquids and using baking soda…hmmmm, I just wondered! Turns out you can freeze vinegar and it freezes really well! (mental note to self!)
I dumped a little baking soda into our flat plastic bowls (the ones I use when we batter fish) and grabbed our tray of vinegar from the freezer. This was a great activity for my kids as they love the feel of the bubbles that vinegar and baking soda make. They kept adding more and more vinegar ice cubes to the baking soda to create more and more bubbles. I am pretty sure they played with the whole thing for well over an hour.
