Exactly how I remember

Was telling a younger friend about these and how much I loved them when I was young so I decided to look them up. Lo and behold, here we are. It's still fun and it still sounds like a singing mogwai.

Attention Grabber!

I use these balls to open our discussion on circuits. To make it really fun I have my students stand in a circle and hold hands. Then I touch one side of the ball and have a student touch the other side. They get a big kick out of this demonstration.

Absolutely terrible

Energy balls can be fantastic teaching tools. I bought 8 for teaching, one worked. Can't believe anyone would sell these.
