Customer: I’m a high school physics teacher and love science gadgets, especially if I can use them to teach something fun. Often, science toys or demonstration equipment is made cheaply and doesn’t always work. This Sterling engine works amazingly well. It is easy to put together, the parts are well crafted, and it’s easy to get it working. I use a cup of hot coffee or hot water to heat the base. After about a minute you simply need to get the engine going with a little nudge and it will keep working for minutes. The hotter the water the faster the engine goes. Who would have thought?

It's funny to see people's looks and reactions when they squeeze a little shot for this Stirling engine. Put it on the cup which full with hot waters, give the flywheel a gently push, and get the flywheel going, and then it works like charm. All of your guests want to know what happened, ice-breaking success. What a marvelous toy!

To be admired and to be talked more from your friends if you have this magic stuff.

This stirling engine designed reasonable and compact. You can bring it home, school office with convenient in your bag.

ATTENTION:

1. Only use a little graphite dry lube quiet it down nicely if there is a little noisy. You can scratch off the graphite from the pencil with a knife.

2. Prohibit to add oil to lubricate. Because the oil will mix with dust in the air to be oil-dirt. That will make the friction to be even bigger. The stirling engine can't run freely then.

PACKING LIST:

1* stirling engine. 1* very detailed user manual.
