    When nothing much is going on at work, I make a cup of tea and put this Stirling Engine on top. A couple minutes later I give the flywheel a little nudge and it starts spinning away. On a large coffee mug filled with boiling water, it will spin for about an hour and fifteen minutes. It arrived with no instructions as is to be expected but I find figuring out how something works to be part of the fun of ordering from Banggood. I figured out how to bend the supports to get the flywheel to stay on but still turn freely. A friend added some graphite lubricant to get it going really fast. The first question out of coworkers mouth is alway "Where did you get that?" I answer "From Banggood.com." Then I add "And to answer your second question, contrary to what you might expect from the name, Banggood is not an adult site."

    Cool Gift! Was brought as a gift for someone, they really loved it. Great to watch and works on the smallest amount of heat. Great service from Bangood!

    Well, this is one of my standard mugs that I normally use for coffee. But now, when the coffee is ready, I prefer to wait a bit until it gets less hot and to see this nice Stirling engine turn for about a quarter of an hour. When you put the engine on the mug, you need to wait about half a minute and then you have to turn the wheel by hand a bit to start the engine. From then on, it'll work on it's own until the heat from the mug has lowered too much to make the engine turn the wheel. I had this interesting engine for some time on my wishlist but I waited until the price dropped just below the amount that the customs in The Netherlands could decide to make me pay VAT. When the engine made it into the Flash Deals at Banggood, that time had come and I immediately bought it. And I'm not disappointed at all. The Stirling Engine works great for this price. It's a nice item to see the basics of a small engine working on nothing more than a (relatively) small difference in heat. I couldn't make it start turning on my hand but it works great on a mug of coffee, the or the lid of your cooking pan. The item made of metal and glass and is manufactured very well and I'm sure it'll last a long time. You need to assemble the wheel and body of the engine when you unpack the item but that's very easy and will take about a minute and then the fun begins... Don't worry about the packaging since Banggood packed the item very well and it arrived without any damage. Thanks Banggood for another great item!

    Dieser Stirlingmotor ist ein kleines, hübsches Lernspielzeug und ist gut verarbeitet. Allerdings ist das Schwungrad verdreht, so dass es zu Reibung mit dem Glaszylinder kommt. Wer Interesse an dieser Art von Modellen hat, sollte dieses Produkt nicht missen. Ich habe darüber bei Youtube 2 Videos gemacht: https://youtu.be/R9XKzKJ7Fr4 und https://youtu.be/B5lzZpJxwfs --------------------------------------------------------------------------------------- This Stirling engine is a small, pretty educational toy and is well made. However, the flywheel is twisted so that it comes to friction with the glass cylinder. Anyone interested in this type of model should not miss this product. I made about it on Youtube 2 videos: https://youtu.be/R9XKzKJ7Fr4 and https://youtu.be/B5lzZpJxwfs

    very cool experiment. runs great and much faster than I anticipated. in my experience, so far, you will need to give it a slight push to start it but if it has conducted enough heat on the bottom, then it will run very fast and you can then remove it from the heat source. I would recommend using hot water, as water can’t melt the plastic piece that is used to house part of the piston. ordering several more.

    Works right out of the box, seriously. No instructions needed. Put the flywheel on the pivots. Attach the two piston hooks, Put over steaming cup of tea. Wait for about 30 to 45 seconds. Give the flywheel a flick, and away it goes. Speed depends on how hot the tea is! Well built with fine material.

    I agree with all of the positive comments posted so far. It is just the right size to sit on top of a cup of hot coffee/tea, and works well on that much heat. Also works, in the opposite direction, on top of a bowl of ice cream. Put your hand on top after a little while and watch it accelerate. Highly recommended.

    Maquina que funciona con la diferencia de temperatura entre la parte inferior de la superior Muy bien embalada, incluye un regalo. Facil de montar y hace el ruido que tiene que hacer una maquina de estas características. Un día de estos le pondré grafito en los ejes Operated machine the temperature difference between the bottom of the upper Very well packaged, it includes a gift. Easy to assemble and makes noise to do a machine of this kind. One of these days I will make him graphite shafts

    Very simpathetic for me. I put it on top of my electic oven and...zac...it began to spin. A good way to start my day: a toast and a Sterling engine dancing ;). It works on a rigid ice pack too, for more than 3 hours. Attention: don't heat it too much without rotation. The metal axis is only inserted on the syntetic material and with excessive heating looses aderence. I opened it and pushed the axis more inside the synthetic material. Could be useful to put a drop of glue.
