Instant Hot Tub? Just Add Water and Quicklime

This is how you make a hot tub, hillbilly style. Three guys from the prairies of Illinois turned an old stock tank sitting in the open air into a jacuzzi, and heated it up using quicklime, that scary caustic stuff that burns your skin off if you're not too careful. A video of how they did it, using gas masks, tin baths and a lot of ingenuity, is after the jump.

Hot tubs: discuss. I'm sort of a fan of them, but can't quite get over the hygiene bit—or, in some cases, the molded plastic naffness. The Lay-Z Spa is a blow-up hot tub with enough room for six people to contract Weil's disease at the same time. The 1200 litre capacity tub has massage jets, a rapid heating system and apparently can be set up easily. Would this US$1,000 monster work well with those crazy Swiss guys who like organising 
An eco-friendly hot tub, the Dutch Tub looks like something out of a soft-porn Euro flick from the Seventies. Which is A Good Thing.
Apart from its looks, the $6,000 tub has rather a special USP: As well as being totally transportable (throw it on the top of the SUV, don't forget the fuel, find a nice spot and set it up) the log basket doubles as a cooker, meaning you can barbecue while you stew.
