This was a fun little activity! And you can make it with the supplies you have leftover from THIS activity plus a little cornstarch!
Here's what you need:
Borax
school glue (clear or not)
cornstarch
plastic cups
craft sticks for stirring
measuring spoons
food coloring (optional)
1) Dissolve 1/2tsp of borax into 2 tbl of warm water in the first plastic cup. Stir until dissolved. Add food coloring if you would like.
2) Put 1 tbl of glue into a second plastic cup. Add to that 1/2 tsp of the borax solution and 1 tbl of cornstarch. Let it sit without stirring for 10-15 seconds.
3) Stir with the craft stick until you can't any more. At that point take the impossibly sticky glop and begin to form it into a ball between your hands. Eventually the stickiness will subside and you will have a bouncy ball!
These bouncy balls do not hold their shape forever. They must be stored
in a plastic bag to keep from drying out but the boys still had a great
time making them and now I have 1tsp left of the hug box of borax I
bought! :) The balls are bouncy and it is very fun (for parents and kids alike) to see science at work!
