1. In this one you'll need: glue, borax, food coloring, cornstarch, and warm water
2. In one cup, combine the warm water, cornstarch and borax. In another cup or bowl, put the glue.
3. Next, add several drops of food coloring to the white glue and stir well.
4. Give your water/borax/cornstarch mixture a good stir to combine all the ingredients (the cornstarch has a tendency to settle on the bottom). Then pour the water mixture into the colored glue.
5. Stir and you'll see it immediately start to clump together. Stir a bit more until you have one big, slimy glob.
6. Take the glob out of the liquid and begin rolling it between the palms of your hands to form a ball. It'll be sticky at first, so keep a paper towel handy to wipe off your hands occasionally. Soon a rubbery ball will form. (We found that just using our palms seemed to work better than using our whole hands and fingers.)
7. Once the stickiness is gone and you have a nice smooth ball, that's it! You can bounce away!

The balls will flatten out after sitting for a while, but storing them in small plastic containers and then rolling them between your palms again will help the super bouncy balls regain their shape.

This is what you'll need: borax (found in the laundry section of the store)

• cornstarch (found in the baking section of the store)
• white glue (e.g., Elmer's glue - makes an opaque ball) or blue or clear school glue (makes a translucent ball)
• warm water
• food coloring (optional)
• measuring spoons
• spoon or craft stick to stir the mixture
• 2 small plastic cups or other containers for mixing
• marking pen
• watch with a second hand
• metric ruler
• zip-lock plastic baggie
• 1. Label one cup 'Borax Solution' and the other cup 'Ball Mixture'.
• 2. Pour 2 tablespoons warm water and 1/2 teaspoon borax powder into the cup labeled 'Borax Solution'. Stir the mixture to dissolve the borax. Add food coloring, if desired.
• 3. Pour 1 tablespoon of glue into the cup labeled 'Ball Mixture'. Add 1/2 teaspoon of the borax solution you just made and 1 tablespoon of cornstarch. Do not stir.
• 4. Allow the ingredients to interact on their own for 10-15 seconds and then stir them together to fully mix.
• 5. Once the mixture becomes impossible to stir, take it out of the cup and start molding the ball with your hands.The ball will start out sticky and messy, but will solidify as you knead it. Once the ball is less sticky, go ahead and bounce it! You can store your plastic ball in a sealed Ziploc bag when you are finished playing with it. Don't eat the materials used to make the ball or the ball itself. Wash your work area, utensils, and hands when you have completed this activity
