Distilling usually involves a boiler, some pipes and a condenser with even more pipes. But this instructable uses nothing more than a boiling pot and a bowl to work. Some ice is used to increase efficiency. I like the idea although its most unlikely that i will ever use it unless for educational purposes :D
Place the bowl inside the pot, and place the cover of the pot upside down. The water to be distilled is placed in the pot. Ice is placed on top of the cover. As the water evaporates it reaches the cold cover and it condenses back to water. It then slides towards the middle of the cover. Then it falls down into the bowl in the form of water droplets. Brilliant!
