Bobbing for Apples

The wet version.
This is the most classic version of the game. You'll need to get a tub or similar container capable of holding water, some towels to dry the contestants off, and of course many apples.
The first thing to do is to remove all stems and leaves from the apples.
Next fill the tub with some apples and fill to within a few inches of the top with water.

The children take turns trying to retrieve an apple with only their mouth!
 As simple as this sounds it is quite tricky. Generally prizes are awarded to the first person who can successfully retrieve an apple.

The dry version.
For those who would rather remain clean and dry there is another popular version.
For this version you will again need apples, several lengths of string or twine, and a suitable place where you can hang apples from.
Tie the string to the stems of the apples and tie the other end to either a tree branch or a pole supported by a couple of ladders.
The object is the same to retrieve an apple using only your mouth.
