I gave a second life to my cracked salad spinner after taping it up! It works great!
We used squirt bottles from some hair dye kits for the paint. It was tempera paint, not too thick and not too thin. Try to squirt it in while your salad spinner is turning. A little tape, or wedging the paper in place in the basket will help keep it from whirling out when you take off the top of the spinner.
The children loved it and look at the results! Don't you want to try?
