Mix 2 tablespoons (30 ml) of warm water and 1⁄2 teaspoon (2.5 ml) of Borax until the Borax is completely dissolved. Stir vigorously to ensure there are no clumps of powder left in the bowl. Heat the water in the microwave or on the stove until it’s warm to the touch. It shouldn’t be boiling. You can find Borax in the laundry aisle of a store. Borax is safe to use, but it's poisonous if ingested in large quantities. If you or your child get it in your eyes or mouth, contact poison control immediately. 3 Add 1⁄2 teaspoon (2.5 ml) of the Borax mixture in the bowl with the glue. Do not stir the ingredients together when you add them. Simply pour the Borax and water into the other bowl containing the glue and cornstarch. Set aside the remaining Borax mixture if you plan on making more balls. 4 Let the mixture sit for 15 seconds. This allows time for the Borax to react with the glue, making the polymers of the glue link together which will create the ball shape. If you start stirring right away, the bouncy ball may not form or harden properly.[1] Set a kitchen timer or use the clock app on your phone to keep track of the time. 5 Use a spoon to combine the ingredients until they’re too thick to stir. Within 1 to 2 minutes, the mixture will thicken. Stir vigorously while the mixture is still liquid to make sure the ingredients are blended well.
