There are a few different ways to make spin art. You can visit your nearest carnival, try one of the kits from Melissa and Doug, Alex or Rose Art, or use a humble kitchen gadget.
Salad spinners are easy to find at thrift shops and yard sales, and we'd much rather designate one for this activity than worry about washing all of the paint off. Paper should be cut down to size or you can use paper plates. Secure your paper to the bottom of the salad spinner with a little tape then invite your child to squirt some tempera paint, put on the cover and give it a spin.
The terrific artwork shown above was made by Tammy of In Stitches with a spin art machine by Rose Art which she found in her son's closet. Click over to see a very practical tip for making something similar without making a huge mess.
