This is a classic fun art activity but I'd never ever done it with my son. My salad spinner died a few years ago and every time I saw one in the store it was $20 or more and just to use it for art seemed indulgent. Then I saw this basic and oh so cheap $3 one and the plan was hatched!
1. Gather your materials. You will need some paper plates, liquid paint and a salad spinner.
2. Cut your paper plates so they fit in your spinner.
3. Pour in some paint.
4. Pour in some more!
6. Try different combinations of color and keep going.
