Equipment: four buckets, two each of several (maybe up to a dozen) things, but they must all fit in a bucket ... tent peg, fish slice, piece of rope, lid, ladle, ball ...
Two full buckets go at one end of the hall, and the empty ones at the other end. Two teams of equal numbers, numbered 1, 2, 3 etc.
Organiser calls out
a number and an object, and one from each team collects the object and
runs to put it in the bucket at the other end.
After a while, the competitors need to know which bucket the item is in!
Shouting in quick succession: four ... ball ... ... four ... ball can cause great confusion.
