If you have seen this activity on Pinterest, but have yet to try it, then you are missing out! It is a must try!
It only requires a big pan or tub, a big box of baking soda, a few small bowls of vinegar, food coloring, and medicine eye droppers. Most of these things you probably already have! Just poor the baking soda into the pan, fill a few small bowls with vinegar and add a few drops of food coloring to each bowl and let them go at it dropping droppers full of vinegar into the baking soda! We have done this activity several times and the mess is (almost) always minimal. The time it keeps him busy always outweighs the time it takes me to clean up the mess. Last go round he stayed entertained for over an hour! Only took 10 min to clean up, so I would say that's a win!
