Glittery Volcano

This project is part science experiment, part sensory fun! The volcanic reaction of vinegar and baking soda, with some glitter for extra sparkle, exploding over corn starch made some wonderful pretend snow to play in. Although easy to set up, it occupied my kids for nearly an hour afterwards.

  • Step 8

    Watch the volcanic reaction! Immediately, the mixture will foam and rise out of the bowl, spilling over onto the cornstarch. (For more information about the science behind this volcanic reaction, watch this YouTube video.)

  • Step 9

    When the mixture is done foaming, dump any of the remaining volcano into the cornstarch.

    ...and built snow mountains for our people figures to climb and play in.

  • Done!

    Lego figures were fun to play with, too. This pirate has conquered the mountain. (Argh!)
