bukster;1418855; said:i'm still trying to figure out the one in the video. how does the water in the tower not dump out into the bottom portion? i mean i know it's possible with a vaccuum in the tower but they've got air going up through it. so that's not the case there. anyone have any ideas on how it's done?
