The engine itself is charming but the delivery took longer than expected, which was a bit of a letdown. A touch smaller than imagined, though it still sparks curiosity.

bought it as a quirky addition to my desk. the design is quite striking, and it fascinates the kids when they come over. Would’ve loved a slightly bigger size but still pretty fab!
Emma Clarke –
my son was absolutely chuffed when he saw the flying saucer design! We enjoy watching it whir away, it’s such a neat mechanism. It really does blend retro and futuristic perfectly. Perfect for sparking a lot of imaginative conversations with him.

regular science gadget shopper here. Stirling Engine UFO is a cracking little item. Quite pleased with the design, although a tad pricey for what you get.
Margaret Hollis –
bought this for my grandson Oliver who’s seven and he hasn’t stopped chattering about it since the postie dropped it off. He sat it on a mug of hot tea and his eyes were like saucers (pardon the pun) when it started spinning all by itself. Now he’s demanding to show every visitor, bless him.

Spot on. Sits on a hot drink and the temperature difference between the warm base and cooler air above drives the little piston, so the whole thing hums round with no batteries. Looks cracking on my desk too.
