  • 1/2 cup warm water
  • 1 tablespoon cornstarch
  • 1 tablespoon baking soda
  • neon food coloring neon food coloring (or liquid watercolors) You can experiment with different colors.

Instructions
 

Preparation

  • In a mixing bowl, combine white school glue and warm water. Stir until they blend evenly, creating a consistent base.
  • Add several drops of neon food coloring to your mixture. Experiment with colors to achieve your desired shade. Mix well.
  • Gradually sprinkle in cornstarch and baking soda. Stir continuously to avoid lumps; you want a smooth texture.
  • Carefully add vinegar to the mixture. You'll see some bubbling as the ingredients react; this is where the magic happens!
  • Once the bubbling subsides, use your hands to gather the mixture into a ball. If it's too sticky, add a little more cornstarch.
  • Roll the mixture into a smooth ball about the size of a golf ball, then place it on wax paper or a silicone mat to dry.
  • Allow your bouncy balls to cure for 24 hours for optimal bouncing power.

Notes

You can mix different neon food colors to create unique shades. For a sparkling effect, blend in biodegradable glitter before the vinegar. Feel free to mold different shapes like stars or hearts, instead of traditional spheres. Adjust the size of your balls for different bounciness levels; smaller balls tend to bounce higher.
