Get a Nurfgun revolver, put one dart in the chamber, spin the chamber,
put it to your head, cock and shoot.
If the dart shoots you, you take a shot (or a swig a beer, whatever).
Two variations.
1, continue to pass around the gun without respinning the chamber until the dart is fired.
Best played with a # of players equal to or less than the # of darts the chamber holds.
2, Respin the gun each time it is passed. To create a better ‘kill’ ratio, more darts can be added.
