After a unique gift for Christmas? One that goes "choo-choo" and could potentially power the world's most adorable train? Well, this tea candle steam engine from Wilesco could be the ticket, though the price might be a tad too steep for what it is.
Yes, it's a glorified candle holder, but trust me, when you see it in action, you'll realise it's so much more:
Tea Candle Steam Engine: a functional piston steam engine complete with boiler and flywheel. Takes about 2 minutes to get going after the candle is lit. The invention that powered the industrial revolution on a desktop! Made by Wilesco. ➡️ Follow the link in my profile for info on where to get this and many other items featured here on @physicsfun #physics #physicstoy #heatengine #steamengine #thermodynamics #candle #science #scienceisawesome
It's tiny, weighing just 300g and would look fantastic on pretty much any desk.
The only problem is the price -- $US95 ($125), plus $13 shipping from Amazon is quite the ask. That said, if you think it's the ideal present for a certain person, there's only three left in stock at the time of writing. Don't spend too long contemplating your purchase.
