Everyone at your party will love this game. While you are at the store gathering items for the party, you should also pick up a sturdy potato and a jar. Make sure that the potato is large enough for guests to hold between their knees, but will also fit in the jar you have selected. If you plan on a large number of guests, you may want to get two potatoes and jars to keep up the pace of the party. At the party, place the jar on one side of the room and have guests line up on the other. Each guest will take a turn. They should hold the potato between their knees and walk from the starting point to the jar, and then drop the potato into the jar. Each guest who successfully completes this task gets a point. After everyone has had a turn, the guests with tied scores will face off with another turn. Continue the challenges until there is a winner. To make it more challenging, you can move the jar to a different location and select a new starting point with each round. The winner should get a door prize.
