Sunnytech Low Temperature Stirling Engine Motor Steam Heat Education Model Toy Kit (LT001)

バルク品ですが、商品は素晴らしい物でした。、低温度で動くものですが、手のひら上でちゃんと動きました、感動です。

I got this for my very gadget driven husband and he loved it. He loves seeing how things work and this is a fun toy that he uses almost daily. You should definitely wipe the bottom of the device dry when you are done using it.

Exactamente como describe las especificaciones. Excelente artículo!!

Nice product, the side transparent portion makes me to understand the mechanism easily. I've tested it with a cigarette lighter, and excellent

This is a great gadget and a lot of fun. It comes fast, works well, and is easy to assemble, though you may want to have a tiny screwdriver or dull knife point to click the two little drive shafts in place. It's super easy and the instructions are good. It took me fewer than five minutes to set up. The great thing about this, which is better than other similar products, is that you don't have to light a fire or use a candle or anything like that. You simply place it on the top of your coffee cup. You can put it on a hot beverage cup you want to keep hot, and watch the little motor do its cool thing, or you can microwave some water in a cup for two minutes and set this gadget on top of the cup for lots of fun. Kids are blown away by this and it is a real conversation piece for adults. Any kid would love to get this as a gift--birthday or Christmas or whatever, because everyone drinks hot tea, hot coffee or hot chocolate at some point, and if not, just hot water--no open flame. Also it is great for teaching kids about external combustion engines and the principles of physics. I haven't had it long, but already its my favorite gadget to play with in the kitchen while I am waiting for the rest of my meal, and I can't wait to show my friends when they come over for dinner. Just a lot of fun without an open flame or any dangerous substances to ignite.
