OKAY THIS IS TOO MUCH FUN! MOVE OVER RED SOLO CUP, YOU HAVE ANOTHER PURPOSE!!!\ Magic Party Cups... great idea for kids parties! Put some drops of food colouring into the bottom of cups and wait for it to dry a bit. Fill the cup with ice, then pour in clear drink (water, sprite etc) and watch the kid's excitement as the drink changes colour.
