Scoop out a small area in the middle and place a cup in the center.
Pack the snow around the cup, re-forming the volcano shape.
Add baking soda to the cup.
Add dish soap to the cup.
Drop a few drops of food coloring in the cup.
Using the squeeze bottle squeeze vinegar into the cup. The baking soda/vinegar/dish soap will react, start to rise, and flow over the sides of the cup!
Squeeze more vinegar to see if the volcano will continue to react.
