volcanic eruptions

I found a book called 365 Experiments the other day and picked it up because I thought it would be fun to do with the kids. It felt like I was pulling teeth for them to do just one of the experiments in there (and I let Jake pick). He's doing his best to look like I abuse him here in this picture.

The first experiment the boys did was a volcano. The book called for:

play-dough (I used modeling clay)

film canisters -- you know how hard those are to find these days? I just used up two glass spice jars so I washed and used those.

1 tbs baking soda

1 tbs vinegar

(we used a lot more, because we wanted to see some real action)

We pretty much just stopped measuring and poured the vinegar right in. You can see Jake here with a hint of a smile.
I forgot to mention nails...they weren't part of the original list, but the kids wanted something to represent all the people that get fried with hot lava....how did I raise such blood-thirsty beings?

I also made them look up what actually causes volcanos to erupt and why vinegar and baking soda have such a reaction and made them write it in their own words, because I'm a mean horrible mommy (at least that's the impression I got with all the eye rolling -- they'll thank me later -- right?).

Next week it's how to make limestone....Isaac's choice. It calls for shoeboxes and I have none, I do believe that's a reason to go shoe shopping. I love science.
