Day 1: mini volcanos

Step 1. Gather the ingredients. Step 2. Set up (and make your children say cheese). Step 3. Watch as the water foams! This was fun, but if we do it again, I'll need a lot more baking soda and vinegar, and I'd like to make it so the girls can dump it in themselves. They did have fun watching the water bubble and almost overflow, but I was hoping for more.
