A must try for any grown up to teach a youngster something new. This gadget is so amazing. After it starts up you can place it off to the side and it stays going. That shuts up all who think it's steam powered. Put an ice cube on it and it goes faster. All we need are larger ones for electric generators. Show our childern the way of the future. With concentrated sunlight these things go fast.
Couldnt get the first one to work on steaming water so the company sent a new one asap and it works great :)
A nice looking interesting product if it works well.
It's cool. It's like an old man fidget spinner, but it is something to put on top of your coffee pot while it cools down.
Works as advertised, place it on a boiling cup of water, wait 30 seconds and give it a jump start. After that it will run fairly quickly.
