Simply fill the bottom of a pan with baking soda, and give your children cups of vinegar with different colors of food coloring in them.
Let them use eye droppers to drop the food coloring into the baking soda. Great for hand-eye coordination and fine motor skills!
They will have a blast watching the colors bubble and fizz in the baking soda!
My boys stayed outside with this for close to an hour, and they would have stayed longer if they hadn't run out of their materials! I think vinegar and baking soda will be on my next Costco shopping list! This activity was too much fun to not do many more times this summer!
