Review on 💡 Energy Hands by Steve Spangler Science: Unleashing the Power of STEM by Shane Minter

Bought two of these for the kids. Straight out of the box, one didn't work properly. It turns on every now and then, but not always. Don't worry about returns. Rubbing the open palm usually solves the problem, but not always. Was hoping for a fun little science lesson for the kids; and I think I have, but they don't work often enough to try again. I would look elsewhere.
