Equipment

  • 1 plastic cauldron
  • 1 set of measuring spoons

Ingredients

  • 2 tbsp baking soda
  • cup vinegar
  • 2-3 tsp green jello powder
  • 1 tsp dish soap optional

Instructions

  • Start by adding about 2 Tbsp of baking soda into your small plastic cauldron or bowl.
  • Next, Add 2-3 tsp of green jello to the cauldron. You can use food coloring here too, or water color paint. The jello smelled better so we went with that! This is also when you can add your optional dish soap. To keep it more toddler friendly go with the jello powder only.
  • Slowly begin to pour your vinegar into the cauldron and watch the fun chemical reaction take place!
