Egg and Spoon Race
Have lots of raw eggs and spoons on hand!!  Each guest picks a partner; one stands on one side of the yard and the other on the opposite side.  Each has a spoon.  One team member places a raw egg in the spoon and the race begins upon ready, set and GO!  The object of the game is for the partner with the egg to race to their partner, transfer the egg without using their spare hand and for the partner who now has the egg to race back.  First one back wins.  This can be done in relay teams, as well.  In case of a tie, there is a race off between the tying teams.  Have fun!
