Orange juice , Optional: ginger ale,                     
           Alcohol of some kind                     
           Blue food coloring             

          Put some blue food coloring into the orange juice punch until it  turns a disgusting swamp-green color.  The color is      gross and the  orange juice pulp floating around really adds to the effect.

  People will realize that the punch tastes good, but it will take  them awhile to figure out it is orange juice.
 
  Floating Arm-of-Death
 
  Water or orange juice
  optional: gummy worms
 
  Freeze the water (and gummy worms if desired) in a clean rubber glove.  Peel off the rubber glove and float the arm in the punch.Very effective .
