Catch the water balloon!!!
How To Play:
Get teams of two players. Have each team blindfold one of the players. The player that is blindfolded is the one tossing the balloon to the other player. All the other person has to do is catch the balloon. You can tell the blind person that their teammate is far away or close. This will mess with their throw strength. If this is still easy make the person catching the balloon have to keep one foot in the same place.
