Abstinence

fill a shot glass with abstinence. hold the tongs of a fork over the shot glass and rest a sugar cube on the tongs. Light the shot on fire until the sugar begins to melt and drip into the shot. Allow for a few drops then blow out the fire. drop the sugar cube in and take the shot. Be careful not to choke on the sugar cube. a hint would be to bar your teeth to stop the cube from fully entering your mouth.
