Dyson Air Multiplier 10-inch Table Fan ($299.99)
When we first saw this Dyson bladeless fan, we were convinced it operated on black magic. But, in actuality, it has a jet that draws in air and propels it at 15 times the normal speed. No blades means none of that unpleasant "helicopter" effect you get from some fans, plus it's safe for curious kids and easy to clean.
