You will need to fill a large tub with water. Then you blindfold the players. While they are blindfolded you put all kinds of objects into the tub. They then take turns at fishing out one object, they then must guess what it is, if they are right they keep the object otherwise it goes back into the tub. Once all the objects are identified the players have their blindfolds removed. The person with the most objects wins.
