Sewer Float

12 oz root beer
4 scoops vanilla ice cream
food coloring
gummy worms

Place the ice cream scoops in a tall glass. Drop a few drops of yellow, blue and red food coloring over the ice cream. Slowly pour the root beer over the ice cream. You can add more food coloring if needed to make it a more disgusting color. Drape several gummy worms over the edge of the glass.
