A second variation: Once again, a large group of different items is the set. Half the group leaves the room, and the other half selects one of the items. Each person left in the room writes the shortest description of the chosen item that selects it out of the group. The other members come back in and are each given one of the written descriptions and a stopwatch. They read the descriptions and then try to visually find the chosen item without giving obvious indications to the other searchers. Once a searcher thinks he knows which item is being described, he stops his stopwatch to indicate how long it took him. After every searcher believes they have found the correct item, the written descriptions and stopwatch times can be compared as above.

This has the added bonus of providing information on what kind of descriptions are the most helpful in finding things.
