If you think that shot glasses are simply for downing the likes of vodka, sambuca and tequila, then quite simply, you ain't seen nothin' yet, to quote a song from the 70's.
These shot glasses are also provided for the group to have bundles of fun with, as the aim of this game is to get a ping pong ball into one of your mates glasses and if it does land, the owner of the glass must drink whatever happens to be in there at the time.
