what do u guys think of these? any good? im also looking for something thats a little better for my lungs....any suggestions? thanks
dude those vortex things are pretty cool i guess, just outrageously overpriced...and acrylic I highly suggest you try your hand at makin a sobe waterfall, there are a bunch of tutes around here somewhere. Those work just as well, made of glass, and will cost no more than five bucks
