I had a friend a long time ago who had a cylinder style vaccuum cleaner that they made a monster bong out of - they just ran it backwards and it went through a big water jug - but it would go through ALOT of weed, but for a party, it was great! Run it for like a few seconds and the jug would be full and people could smoke at will - it was more like a big ass vapo that you had to add the fire to.
