We've been to a couple birthday parties for the toddler set lately and the cool party item is the paint spinner. You put a piece of paper in the spinning machine, drop little drops of paint and spin away. When the spinner stops you have unique pieces of art. They rent machines for about $40, but we bought inexpensive, paper spin-it-yourself versions at Michaels Crafts Stores for just a few dollars. Either way, it's loads of fun.
