Witch's Brew 3 pints grape juice 1 1/2 pints club soda Grapes Apples Mix the grape juice and soda in a pitcher. Halve the grapes and take out the seeds. Cut the apple into small chunks. Float the fruit in the brew just before serving; by magic, the grapes and apples will look just like eyes and teeth. Make a swizzle broomstick from a straw and black paper cut into a fringe.
