May we serve you some (very) fast food?
Setup: You'll need a starting line, a designated turnaround point, and two teams (with at least two players per team). Also, a large plastic dinner plate and a Ping-Pong ball for each team.
To play: The first runner on each team places the Ping-Pong ball on top of the plastic dinner plate. Holding the plate waiter-style (one hand underneath the tray; younger racers can use two hands), the player carries it to the turnaround point and back to tag the next teammate, who does the same. If a player drops the ball, she picks it up, puts it back on the plate, and resumes. The first team to finish wins.
