I first got saw this game on the Youth Leader Stash website. Unfortunately, it seems that their website crashed and never recovered. It’s a great game though. Here’s the idea.
Everybody gets penny. They lean their head back and place the penny on their chin. The players then try to knock the penny off of everyone else’s chin without dropping their own penny. If a player touches their own penny with their hands then they are out. The last player with a penny on their chin is the winner.
