At Home Bouncy Balls

A fun STEM project that will entertain all ages!

July 24, 2024

Learn how to make a bouncy ball in less than 5 minutes, using a few simple ingredients!

Materials:

  • 1/4 cup Boiling water
  • 1/2 Tablespoon Borax
  • 2 Tablespoons Elmer's clear glue
  • Glitter

Equipment:

  • Measuring cup
  • Measuring spoons
  • Small bowl
  • Spoon


Instructions:

  1. Pour boiling water into a measuring cup, then add the borax.
  2. Stir well until the borax is dissolved. Set aside to cool.
  3. Add the clear glue to a small bowl.
  4. Add glitter in your favorite color. Stir until the glitter is well combined with the glue.
  5. Add just enough glitter that you can see the color in your mixture (about 1/4 teaspoon or so). If you add too much glitter your ball won't have the cool see-through look to it.
  6. Add 1 teaspoon of the borax mixture to the glitter glue and stir.
  7. Add another teaspoon of the borax mixture and stir until the glue becomes jelly-like and too difficult to stir anymore.
  8. Pick up the thick slime and squish it together with your hands, making sure there aren't any sticky glue spots remaining.
  9. Begin to shape it into a ball.
  10. Roll the ball in-between your palms, like you would a ball of cookie dough. It will still be wet at first, and difficult to roll, but just keep going! It will become easy to roll fairly quickly.
  11. Continue rolling until you have a nice round shape. 
  12. Wet your fingertips with extra borax mixture and smooth down the outside of the ball. (You can also put the ball in a round mold to give it a perfect sphere shape.)
  13. Now have fun playing with your bouncy ball! Your DIY bouncy ball is complete!
