Well I picked one up at spencers gifts for 40 bucks, its a pretty cool machine but not exactly what i expected. This is a 700 watt model so it makes LOTS of fog. I mean LOTS!!!! Enough to set off every smoke detector in my apartment after only 2 blasts of the button. On the other hand lasers look really neat! I got a good fan effect by using a prisim and setting up a few mirrors had me drooling. Now im airing out the bathroom cause thats the only room with no detectors in it. Is there a way to make the fog stay lower to the ground? Maybe by raising or lowering the temp of the room????
