Special equipment: 8 chilled pilsner glasses
Arrange all of the ingredients so the guests can help themselves.
To make the float: Spoon two scoops of the ice cream of your choice into a chilled pilsner glass. Drizzle with a tablespoon or two of fudge or caramel sauce. Pour half a bottle of root beer over the ice cream. Top with a brandied cherry if desired.
Serve with a long spoon and a straw.
