There's an old riddle that asks how you can always tell who the town barber is. The answer is that you find the person with the worst haircut in town, because the barber would either have to perform it on him- or herself or get someone less capable at cutting hair to give it a shot. The Flowbee is an invention that promised to turn you into an expert barber even if you're performing a haircut on yourself.
The invention combines electric shears with a vacuum cleaner. Invented by Rick Hunts, the device pulls your hair through suction and trims it with recessed blades. The vacuum collects all the trimmings so you don't have to worry about a mess. The extensions allow you to cut hair to lengths of just a half-inch (1.3 centimeters) all the way up to 6 inches (15.2 centimeters) with quarter-inch increments in between.
It's not exactly a trip to the beauty parlor, but the Flowbee creates an easy way to cut hair. And the commercials are a hoot, too!
