How to make a bouncy ball:

Bowl with borax powder being added.
  • Step 1. In a small bowl, add ½ cup of warm water and borax power. Stir until you dissolve the borax or it is almost dissolved.
Glue being added to the bowl.
Spoon in bowl ready to combine.
Cornstarch being added to the bowl.
  • Step 2. In a separate small bowl, add glue and paint. Mix together the slimy material well.
  • Step 3. Add cornstarch to the borax water and mix the borax solution well. Pour in the glue to the cornstarch mixture. You will see the glue mixture start to harden. It will become a hard glob and not mix well with the borax water.
  • Step 4. Knead the glob with your fingers, while in the water, removing any bubbles. Continue to mix thoroughly.
Hand mixing together the ingredients.
  • Step 5. Remove from the water and knead in your hands.
Mixture in hand.
  • Step 6. Divide the material in half and shape it into a ball by rolling into your hands. Continue to roll and shape for a significant amount of time.

    It will take about 20-30 minutes. The longer the better. Bounce the ball and reshape if necessary.
Mixture broken into 2 mounds.
  • Step 7. Enjoy this homemade bouncy ball. It is so fun and a cool science project. This makes 2 super bouncy balls.

How to store bouncy balls?

Store in an airtight container or your ball will dry and crack. You can place the ball inside a plastic bag or container. Either option is great.

How long will homemade bouncy balls last?

The bouncy balls if left for any amount of time will start to flatten. They will go flat due to the type of material used.

Just roll them in your hand and shape the disc back into a ball shape. It is very simple to do and you can easily form the ball again.

Tips for homemade bouncy balls:

  • Food coloring. Mix in your favorite color to give the ball a pretty look.
  • Glue. You can use glitter glue to change the look and add a fun sparkle. We recommend Elmer’s glue for best results. Generic brands just don’t seem to work as well.
  • Play with them to help form the shape. The more you play with these, the better they work! You need to play with them and keep rolling them into a ball frequently. Bounce, roll into ball, bounce, roll into a ball.

    The kids can help with this. They will enjoy playing with them and “helping” the glow in the dark balls to take shape. They will flatten a bit if you let them set, so the more you can work them the better.
  • Store properly. It’s also very important to store the bouncy balls in an airtight bag. This will ensure they last longer for lots of play time.
  • Be careful with younger children. Be careful with smaller children. You do not want them to put their hands in their mouth as they are making this. It contains borax and hands should be washed thoroughly once finished.
