Now take a nice big glass of water and dirty it up. Mix a good amount of dirt into it and turn it into mud. My daughter loved this part. Pour your muddy water into the top of your water filter and watch it slowly saturate the layers and make its way through your filter into the glass beneath

This is a vacuum I call the Bong-Vac. I designed it specifically to cleanly suck up plaster or gyprock dust using water as a filtration device. Plaster dust is so fine it just kills almost all other vacuums including most commercial units. This one cost me about $60 all up.
The inspiration came from a bong as the title eludes to, although I was not directly inspired from any specific bong or implying ownership of a bong, just a passing scientific interest.
This video shows how to make and use the home made Berkey type water filtration system. This one is made for less than $35 in parts and you will see that it will turn the nastiest of Oklahoma water in to clean SAFE drinking water in a reasonable amount of time. This system is NOT super fast (yet…give me time) but it will clean 5 gallons of drinking water in about 24 hours (Website says 14 per day) . I believe that I may have figured out how to speed that up to 5 gallons in an hour or so, stop back and see it I make that work. This works GREAT and is SOOO much cheaper than the store bought systems that do the same thing.
