Jeff Hume of 180 Youth Ministry submitted this volunteer game you can run with students. Here are the instructions straight from his keyboard. Enjoy.
Hungry Hungry Hippo – Give each participant one of those sticky hands that stretch. In the middle of a round table spread out some skittles or M&M’s. On your go the students try to “grab” the most candy. Put captured candy in a cup and award a prize for the most collected. You could put bonus items on the table or award points by candy color. Student’s loved it! But be ready to have candy flying around the room.
