You can pre-order one right now and back the creators of Hydro Hammock over at Kickstarter, where they launched a crowdfunding campaign that's trying to raise $50,000. Find two very strong trees, hang it up or anchor it and start swinging in the light summer morning breeze, enjoying the either soothing hot or refreshingly cool water. You can swing solo in a single-walled version of this 'swinging swimming pool' or have some serious fun with someone else in a double-walled hammock.

Hammocks are durable and portable, made of sealed synthetic high-tensile-strength fabric. One Hydro Hammock can, according to the manufacturer, easily support the weight of 50 gallons of water along with 2 adults, however 20 gallons of water are said to be sufficient to thoroughly enjoy an amazing bath.

The hammock comes with a portable water heater system, PLG or electric, which is kept in a hard plastic case and uses an LP gas water heater. A 12 volt water pump makes the lovely hot water circulate around you. No matter where you go, you can take it with you and set it up, since you don't really need to hang it (but you must, if you want to swing, of course). You can literally dig a hole in the sand and start the hot tub party right there.

With full equipment the Hydro Hammock will cost you 1,200 USD, but hey... It's a swinging portable hot tub hammock, how can you say no?
