To make the chalk bombs, I mixed a couple of tablespoons of cornstarch and a few drops of food coloring into each cup of water. Using an idea from Find It, Make It, Love It, I filled an empty pump bottle with the homemade chalk paint and used the pump to fill the balloons. The bigger the pump the better it works.
When we had a respectable number of balloons filled with chalk paint, we headed out to the driveway.
My five year old son loved them.
Definitely more fun than regular water balloons. You can turn this into a learning activity using the same ideas as our water balloon letter learning or just draw chalk targets of whatever skill you want to practice: numbers, letters, shapes, math facts, sight words ...
Be sure to come back tomorrow to see what else we did with our chalk bombs.
Do you have a trick for filling water balloons quickly and easily? I hate filling them up.
