Materials Needed: the links take you to examples I like

  • 100% Silicone 1 (Silicone 2 WONT WORK)
  • Disposable Cup
  • Corn Starch
  • Mixing Stick
  • Small Cup of Water
  • Aluminum Foil or Wax Paper Sheet
  • Rubber Gloves
  • (Optional) Dye
  • (Optional) Glow Powder
  • (Optional) Anything else you want to put in your bouncy ball
    • Scents
    • Glitter
    • Get Creative

Steps:

1. Pour enough cornstarch in the cup to line the cup.

 

2. Squirt Silicone into cup with cornstarch

3. Add dye, glow, and any other additives. Mix until it has a nice smooth consistency

4. Add approximately 1 ML of water (less mater makes it take longer to harden and more water makes it harden faster)

5. Mix thoroughly

6. Apply a small amount of cornstarch to hand then put silicone into hand and start rolling. If it's too sticky it either needs more cornstarch/glow powder or needs a bit more time to harden.

7. Aggressively roll between hands, squish it fairly flat as you roll it to get maximum smoothness, eventually roll it lightly & focus on making it spherical. Then carefully drop it onto wax paper / aluminum foil. 

8. (optional) Instead of dropping it onto the sheet you can keep rolling for 10-15 minutes until it completely solidifies to get bouncy balls as spherical as possible without a flat spot.
