Coolest thing ever!
This is one of the coolest things I have EVER purchased from Amazon. No, you aren't going to send these to the moon, but if you are careful you can show your students all about kinetic and potential energy. Small and can fit on your classroom desk.

Crap Product
This just arrived used and scuffed. I set it up before I noticed but once I did, not only did I notice the scuffs, it tangled immediately when trying to use it. These are not finger print marks people, they are a true fading from the coating. Returning today.
