This is a simple ice-breaker. Take a package of good bubble gum. Ask for Volunteers, take bubble gum and chew to music and blow a bubble. The person who has the biggest bubble wins. Make things interesting ie. boys vs. girls, or if you have multiple age groups, Jr. High vs. HS. It is a simple event if you do it to loud music and get everyone yelling it is a pretty good start of a youth night.
