Bong-Vac, a water filtration plaster dust vaccuum
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 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.
