Yesterday at our local dollar store I saw some test tubes (they are suppose to be for doing shots) and I thought of the possibilities for us to have some messy fun. For our first science experiment we started simple. Baking soda, baking powder, cornstarch, and cream of tarter in the test tubes, and vinegar and lemon juice in squeeze bottles.
The test tubes are flat on the bottom so we don’t have to have something to stand them up in, however we discovered that our picnic table’s umbrella hole was a perfect fit. We started by smelling each of the squeeze bottles when we first went outside, and then each of the tubes as we used them. I also told her what we usually use each of the ingredients for, why we have them in the first place.
I love the look of wonder on her face here!
She was quite excited at this reaction, baking powder and lemon juice. It just kept on going until there was no baking powder left. The cornstarch and cream of tarter didn’t have reactions and she was okay with that and ready to move on to the next tube. Once they were all done, she was looking for something else to mix to see what happens.
That lead to mixing everything together in her bucket. There was a lot of noise and some reactions. I think we’ll be doing this or something similar, again.
