Materials Needed:

  1. Assortment of Legos
  2. Plastic Cup
  3. Baking Soda, Dish Soap, Water, Vinegar, Food Coloring
  4. Imagination!

Instructions:

  1. Place the plastic cup near the center of the baseplate.
  2. Start building around the plastic cup with LEGO bricks.
  3. Continue building until you form a volcano (it doesn’t have to be perfect!).
  4. Pour 3-4 tablespoons of baking soda, 1 tablespoon of dish soap, and 5 drops of food coloring in the plastic cup.
  5. Add about ¼ cup of water and mix to form a slurry.
  6. Move the volcano outdoors where there is sand, pebble, or dirt. If you can’t go outdoors, then I recommend putting the volcano on a baking sheet to catch all the “lava.”
  7. Slowly pour vinegar into the plastic cup, and then watch the volcano erupt!
