Soon, we realized that it's an excellent office toy. It's about the weight of a Wiffleball, but it's the size of a softball so it can't be thrown very hard. It's made of bubble wrap so its very soft and unlikely to hurt anyone. The irregular surface of the ball makes it curve an incredible amount. We found ourselves tossing them around or bouncing them off each others' heads all the time.
My daughters won some junky LED necklaces at the town carnival. The squishy covers on the necklaces tore off within 10 minutes, but I kept the LEDs from inside so I could reuse them. I figured this would be a perfect opportunity to introduce the Bubble Ball to the world.
Step 1: Flashing LEDs
To make a bubble ball, all you need is 1 square foot of bubble wrap and some light weight packing tape.
