🍻 What's a Power Hour?

A Power Hour follows the basic format of consuming one shot (1 fl. oz.) of beer every minute for 60 minutes. This is equivalent to consuming 5 beers in one hour. Participants are usually put in a large room with sets of tables. Each set of tables has a few facilitators to hand out the beer and the shot glasses during the event. It's rare that everyone drinks exactly 1 shot of beer every minute. The event usually devolves into just casual drinking and dancing after about 30-45 minutes.
