It really didn’t take long to set up this activity. Of course you could embellish it with extra decorations, but I kept it simple. We used:

  • Old play dough (you won’t get it back to play with after this!)
  • Small glass jar
  • Foil plate (or any dish with sides would be fine)
  • Baking soda
  • Food dye
  • Vinegar
  • Jug

I placedĀ about a tablespoon of baking soda and a few drops of red food dye into the glass jar, then placed it in the middle of the plate. Then I molded the play dough around it in a volcano shape. Previously I have added dye to the vinegar, but I wanted the red “lava” to be a surprise!Classic Play Dough Volcano Activity from Craftulate

I provided F with the vinegar in a jug – about 1/2 cup – and he seemed to know just what to do! He poured it in…

He asked to do it again, but with a different colour. I poured out the vinegar, added more baking soda and dye to the jar, and we tried again. Blue!Classic Play Dough Volcano Activity from Craftulate

He could have done this many times over but I was running out of vinegar! Want to know WHY this happens? Well, the vinegar and baking soda react together to create carbon dioxide – and this gas makes all the bubbly eruptions! We both loved this classic activity!
