I was at walmart yesterday looking for personal fans, which I'm still shopping around for, when I came across a REALLY cool (pun intended) product called cool blast by misty mate. It's a cylinder that you put water in and it has a pump and a hose and a shut off valve. It produces a very fine mist not nearly as heavy as a spray bottle. It doesn't require batteries like mister fans and it wasn't that expensive only 13.99.
