Rainbow Eruption

Materials: Glasses, Food Coloring, Baking Soda, Vinegar (and a bucket if you want a bigger explosion)

E1 & E2 LOVED our science experiment today. We discussed whether or not it mattered if the baking soda went in the glass first vs the vinegar. We watched the level of explosion change based on the amount of baking soda and vinegar. We used tablespoons and measuring cups. The only reason we stopped was because we ran out of baking soda! They really enjoyed it.
