This youth ministry game is a favorite and very simple. Buy some lifesavers and toothpicks. All of the youth are given a toothpick and put in to teams with even numbers and each team is given a lifesaver.
Have all of the teams stand in a line. When the youth leader says go, the youth will pass the lifesaver to each other using only the toothpick in their mouth. If the lifesaver is dropped, the group must start over from the beginning of the line. The first team to pass it to all of their members without dropping it wins.
If teams have more people than another, have some people do it twice to balance it out.
