Juliet’s been asking to do the old baking soda/vinegar volcano trick lately, so we finally went outside and gave it a go. (The first time we tried it in the kitchen and yeah, that was messy!)

I dug up some old toiletry caps, let her fill them with baking soda and then we covered them with cupcake liners. (Why not, right?)

It leant the caps more of a “volcano-ish” feel, so we went for it. Ripping small holes in the tops allowed space for the vinegar to go in and the lava to come out.

The effect was quite dramatic–baking soda and vinegar never disappoint! The nice thing about the caps is that they contained the baking soda nicely and allowed Juliet to continue pouring more and more vinegar to bring on more and more lava.

The fun would probably still be going on if we hadn’t run out of vinegar.

An unexpected piece of fun for Juliet was the varying sizes of the caps–this gave her a small, medium, and large volcano which she enjoyed comparing to one another. As in, “Okay, now it’s the small’s turn! Wow–that’s good. Okay, now it’s the largest one’s turn! Woo-hoo!”

Good cheap fun on a hot summer day. 🙂

This project was inspired by the “Earth” book we got in a chik-fil-a kids meal. Now we are looking for these:
