What looks like a huge cup, requires no electricity and fits four people? The Dutchtub! You see that small fire behind the blonde woman? That is a real fire that heats up the water. It's built for outside use, holds about 200 gallons of water, and has a stainless heating system. You can rent them for parties or for private use, here in America, or buy one for 6K. [Coolhunter]
