A game of skill, a game of challenge, a game of intrigue? Low-Mid buzz factor. Supplies: people, beer, pitcher, and glasses.
Each player will need a glass of beer. Float an extra glass in the pitcher of beer (adding some beer to the glass may be needed for stability). Each player takes turns pouring beer into the floating glass. After a five second wait, the next player then pours into glass. 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. At least, ostensibly.
