A game of skill and nerves.
Supplies: people, beer, pitcher, and glasses.

Each player gets a glass of beer. Float an empty glass in the pitcher of beer (you may have to add some beer to keep it steady). Each player takes turns pouring beer into the floating glass. Only one pour per turn. When the beer stops pouring, your turn is over. If you want to pour a lot of beer, you will have to make it one long pour. Wait about five seconds for the glass to settle. Then the next player goes. Whoever causes the glass to sink must retrieve it and drink its contents. The object is to leave the glass just short of sinking and leave the care up to the next player.

Another variation is to use a pot of water if you don't have a pitcher of beer. Each player will get a glass of water and set aside a glass of beer for the looser!
