A wave board is a special skate board that is in two parts. So not only do you need to skate, you need to coordinate both sides of your body. I think it would land me in the hospital if I tried this. And not just because I'm old, it would have killed me when I was young. But my kids are loving it. It didn't take them long to figure it out. It has to be good for the brain. They have to use both sides of the brain to do this. And it takes them away from the TV and computer.
