A river is set up, by marking the edges with ropes (make it fairly wide), which the blindfolded player can feel with their feet. The blindfolded player cannot leave the confines of the river, but they can walk up and down it. Everyone playing lines up. They then each take their turn one by one. The person playing is blindfolded, (make sure they can"t peek down their nose) then several metal washers are scattered along the river. The blindfolded player is then given a stick with a string at one end, tied to the other end of which is a magnet. This is their fishing rod. The blindfolded player then has 1 minute to wander up the river, collecting as many washers(fish) as they can.
