Two players or teams stand on opposite sides of an oscillating sprinkler.
When the sheet of water passes into his or her side, each player tries to be the first to completely fill a cup or yogurt container.
Here’s the catch: you have to keep both feet planted.
If you take a step trying to get that extra drop (or to avoid a spray in the face), you have to dump out your cup on your head.
Variation: Players gather around the perimeter of an impact sprinkler (the tick-tick-tick, ftttttttwp kind) and, without moving their feet, try to fill a cup as the stream of water passes by.
