My kids love it.

Great science toy for my kids. Something even my 9 year old daughter could operate. Just microwave two coffee mugs of water for two minutes, then place this on top of the mug. A slight touch to start its motion and off it goes.

Art and science - a very cool moving sculpture.

Well made and really cool!

Incredible! Soothing to watch it run and listen to it's distinctive sound. I'm getting another one.
