It’s so simple one can hardly consider it “post-worthy”, yet this is the stuff that little boys are made of. Boys love a good dopamine hit, but the baking soda and vinegar volcano is a tried and true winner. I rarely barter, but this volcano was a result of a little bribery on my part. I can’t remember what I needed Seth to do, all I remember was the joy on the boys faces when I delivered on my promise and handed over the 99 cent box of baking soda. I don’t go to Costco, but I have asked people who do go to pick up baking soda and vinegar in bulk for me. I am planning on keeping my cupboards here at our new house well stocked with experiment supplies. You never know when you will need to pull a volcano out of your hat.
