…but I’m not sure what to call it, either! I found another idea for a cool experiment, for lack of a better word, and decided on a super-hot afternoon to try it out. Unfortunately, this one did not catch Danny’s attention near as much as I thought it would – but Eric thought it was awesome. (And Andrew slept in his crib for 40 minutes to allow it to happen!!)
It takes a few of your basic volcano ingredients: baking soda and vinegar. Jazz it up with a little food coloring and you’re good to go! (Well – you’ll also need a loaf pan, a small bowl or four, and a medicine dropper.)
Prep is fairly easy. Dump a box of baking soda into a loaf pan and smooth it out a bit – all I really did was shake the pan so it was kind of even. At first, the thrifty part of me balked at the idea of using a whole box of baking soda, but then I realized that those cost all of 50 cents. I can handle that for some inside fun that isn’t a video game or movie! Pour a little bit of vinegar into a bowl (or you could use a muffin tin!), and mix in a few drops of food coloring.
Invite the kids to the table! This was also a cool activity for two things: first, it was a cool use of all those used medicine droppers that seem to breed like rabbits in my house. We don’t have medicine for the kids often, but it seems like the droppers are everywhere! (Except, of course, when I want to find them for something like this – then they all seemed to disappear.) It also is a double whammy activity – not only is it a lot of fun, but it’s a great fine motor exercise for younger kiddos!
The whole of this is just to squeeze up some of the colored vinegar and spurt it into the baking soda. Easy to teach! It will, of course, bubble up like crazy, then leave some cool colored designs in the pan. You can go for a little at a time and “draw” with it (what I did to demonstrate), or you would go it at Eric-style and squirt as much as possible as quickly as possible to get huge domes of bubbles.
Super simple, but this entertained my almost-6 year old for nearly half an hour!
