kitchen experiment #2- volcano!

After lunch yesterday we wanted to do one of the kitchen experiments all together. They've been so excited to do the volcano so that's what we chose.
First we gathered up our kitchen supplies: baking soda, vinegar, dish soap, and red food coloring(for added drama), and a measuring spoon.
Oh, and of course a tray to collect the aftermath!
Mickey was in charge of the baking soda- 1 tsp.

Mary Beth added a few drops of dish soap.

Jeffrey squeezed in a little food coloring...
and they all poured in the vinegar.
It didn't disappoint- there was fizzing, bubbling and thankfully, a red eruption.

We kept adding more vinegar to watch it over and over again.
Mickey HATED the smell of the vinegar as you can see.
This was so fun to do with all of them. Afterwards Jeffrey and I went on YouTube and watched footage of real volcanos erupting- cool but scary.
This summer we have big plans to build a large volcano out of paper mache. I've always wanted to do that.

How does it work? When the vinegar and baking soda are mixed together, a chemical reaction takes place producing carbon dioxide- which escapes from the volcano in the form of bubbles.
