Get one baby bottle for each guest. Fill each bottle with a drink of your choice and give one to each guest. When you say “GO!” the guests begin their “feeding time.” The first player to drink the contents of their bottle is the winner.
For a funny variation, seal the nipple on one of the bottles before giving it to the guest. No matter how hard that player tries, nothing will come out of their bottle. You will be surprised how long people will continue to try even when nothing comes out! For all of their effort make sure that player gets a prize, too!
