Make a Bouncy Ball

For each girl you will need:

  • two small cups
  • 1 tablespoon of borax
  • 1 tablespoon of cornstarch
  • 1 tablespoon of white glue
  • 3-4 drops of food colouring
  • two popsicle sticks
  • a small plastic bag
  • warm water
  1. In the first cup measure two tablespoons of warm water.  Add one tablespoon of borax. Stir with a popsicle stick until their are no lumps.
  2. In the second cup measure 1 tablespoon of cornstarch, 1 tablespoon of glue and the food colouring.  Stir wiht a popsicle stick until smooth.
  3. Pour the borax solution into the glue solution.  Stir with the stick and then roll the resulting polymer around the stick.  There will still be liquid in the cup.
  4. Remove the polymer from the stick and roll in your hands until round.   If it is still sticky, roll it in a little more cornstarch.
  5. Now you have your bouncy ball.
  6. Store in a ziplock baggy to keep it from drying out.
