Equipment needed: Big beer bottles, duct tape
Tape a big beer bottle (40-ounces or so) to each of your guest’s hands.
Everybody has to sit like that until they have finished their beers.
When a bottle is empty, it can be removed.
You can set a timer for a couple of hours, and when it goes off, anyone who still has some beer in their bottle(s) has to pour it over themselves or complete a dare.
