The kids will love this game!
You will need a lot of blown up balloons, and flashlights.
Split the group into 4 to 6 teams. You need at least 2 kids on each team. Assign the teams a balloon color. (The more kids you have the more interesting is gets.) Make sure the teams have a station and at least 2 flashlights per team. (We put the stations in the fellowship hall.)
Close the doors to the room the kids are in and have a few other youth leaders hide all the balloons wherever they want around your church. When the balloons are hidden make sure all the lights are turned off in the building. The teams can go out searching for balloons, but they have to find their teams’ color. They can pop other teams balloons. After they can’t find anymore balloons, have them return to their station. Whichever team has the most balloons is the winner.
After you determine the winner, you can tell the kids whoever picks up the most balloon pieces is the 2nd place winner. (It’s a good way to clean up.)
