Note: This gets messy for a bit. You will want to cover your table with newspapers or do this wherever clean up is easy. Also you will need to knead this while it feels slimy. If you have problems handling things that look & feel like snot this craft is not for you.
How we put it together
Mix the Borax and the warm water together in a bowl.
NOTE: This next step happens quickly as the glue interacts with the borax solution.
Using a spoon scoop the two tablespoons of glitter glue into the Borax/water solution and start stirring.
When the glue hits the Borax solution, it starts a chemical reaction that turns the glue from plain glue to sticky polymer.
When the glue forms a solid blob you will need to take it out of the bowl and start shaping it into a ball with your hands.
Keep working the ball until you can feel it starting to solidify and “harden.”
You can put the ball back into the borax solution as you work it. You will probably notice the color changing as well. We used purple glitter glue in our example and as it “cured” it turned a light teal.
For an even bounce, try to make the ball as round as possible. A rounder ball offers a better bounce, more predictability.
Store your bouncy ball in a bag. It is really thick slime so it will flatten out over time. If you leave it on the table or in a small cup it will take the shape it sits in, just reform the ball with your hands and it will shape into a ball. We have kept ours for over a month. It has flattened out a bit, but still bounces.
