can you cut someone with a playing card
This myth was tested on the Discovery Channel program MythBusters, and subsequently debunked. Mythbusters' co-host Adam Savage was already quite familiar with the throwing card trick and was shown to be quite adept at performing it, with his maximum throwing speed being clocked at 25 miles per hour or 40 km/h. The episode also featured Ricky Jay himself, who spoke of writing the book and admitted he is most likely responsible for the genesis of the myth. The hosts were able to clock the speed of his throws at about 90 mph. After failing to throw the cards into a ballistic gelatin target with enough force that would result in injury, they used an electric motor to mechanically launch a card at 150 mph. Offering his own body as a target, host Jamie Hyneman allowed the launcher to be fired at his exposed skin from a few feet away, which only resulted in a superficial paper cut. The hosts concluded that a playing card lacks enough mass to transfer sufficient energy to human tissue on impact.
