Driven by the little lamp, this engine will rotate at speed around 1700-2000 RPM. It's assembled and will run within 5 minutes after opening the package provided you have a bottle of alcohol by your side.

It is a MINI version which can be put into your pocket. A little bit smaller than a 300ml Coca-Cola can. But do not be confused by its size, its quality and performance are guaranteed! We've done special treatment to the machine to avoid rusting and fading; use heat treated high grade spring steel stand to ensure its stability; employ thickened quartz glass cylinder and bearing steel rod to strengthen its robustness; specially designed Lever Mechanism and Crank-rocker Mechanism makes it more ”mechanical”.

It's also a perfect teaching tool demonstrating the process of energy exchange: the hot air in the sealed cylinder enables power piston to move continuously, and flywheel will spin at the same time; periodical air expansion and contraction makes heat energy converted to mechanical energy... Kids will be excited and curious about why. This will enlighten them to explore the world.

Great to keep your dog entertained
Color: Blue
Great toy my 13 month old cane corso absolutely loved it and it kept her entertained forever except she has an extremely strong bite so she was figuring out a way to split it apart so I had to take it away -it’s extremely strong, but not strong enough for the bite of a cane corso but any other dog would love it. I just wish my dog didn’t have such a strong bite and would be able to keep enjoying it since it is a little expensive the only problem with it is that I thought the remote shuts it off, but then her bites were making it come back on, so I don’t know if it was my dog or the toy just doesn’t stay off until you turn it on.

Stopped working within 3 days
Color: Blue
Worked for 3 plays. My 11 week old puppy loved this item. Unfortunately, it only lasted 3 tries before the motor stopped working. $30 for a total of 30 minutes over 3 days is robbery! I'd look at another vendor for the same type of item. We charged it after each attempt but now the motor won't turn on.
