When we go to the store, one of the things my boys usually ask for are bouncy balls. They have always been a favorite in our house, so when I learned you could make your own, I knew it was something we needed to try. I am homeschooling my 10 year old this year and this was the perfect opportunity to fit in some fun with education as we learned about polymers. Try to make a bouncy ball with your kids at home and watch how easy and fun it can be!
- Two plastic cups
- Two craft sticks for mixing
- Measuring spoons
- Borax (found in the laundry section of stores)
- Corn starch
- Food coloring (optional)
Place two tablespoons of hot water into one of the plastic cups.
Put a 1/2 teaspoon of Borax into the same cup and mix well until it is dissolved.
Pour a tablespoon of glue (we used colored glue that we had made before) into the second plastic cup.
Pour 1 teaspoon of the mixture of water and Borax from the other cup into the cup with the glue.
Put 1 tablespoon of cornstarch into the glue mixture and then mix with a craft stick until it gets to hard to mix anymore.
Take the glue mixture out of the cup once you have stirred it up and start kneading it into the shape of a ball. It will be sticky, but will harden and firm up the more you handle it.
Once your ball has formed, have fun bouncing it. Don’t worry if your ball never completely hardens.
