From the video creator:
Homemade Water Distiller! The Deluxe "pure water" Water Distiller! Easy DIY. easily turns dirty water/salt water etc... into clean fresh pure water. produces lots of clean water fast. made from close to 12 feet of copper tubing... along with a few fittings (optional stainless steel tube shown as well). video contains full instructions on how to build it. early testing shows it produces about a quart in 1.5 hrs (and half gallon in 2.5 hrs). note that i soldered on the copper fitting. if you don't have a torch, they sell "push on" fittings that require no soldering. *if soldering, remember to use "lead-free" solder.
