Too lazy to manually shave your head? Try the shaving helmet — a piece of head gear that automagically shaves your head in 20 seconds, without bloodying your scalp.
The shaving helmet uses a "four blade array [of razors] mounted on Teflon-coated aluminum rails" that slide up and down inside of the helmet. LED indicators show you when 20 seconds has elapsed and on the back is an automatic shaving cream injection cycle for the entire cycle.
As shown by the gentleman in the video, it seems to work quite well — shaving his head without littering it with cut and scratch marks. Call me crazy, but what happens if your head isn't as smooth as a volleyball?
Watch the magic happen in the video below.
UPDATE Internet readers are calling shenanigans on the shaving helmet invention, pointing out that the man who demos the gadget has a twin brother. The image of the twins can be seen on Neogaf, on post 21. Looks like the Internet dubunked the Shaving Helmet, faster than the Twins could pull all their digital pictures! Thanks Rob
UPDATE 2: It's confirmed that this video was a viral video hoax. Here is the official making of the Shaving Helmet video. Looks like the Twins swap was how it was done.
