If you have some old corn in your garden or you've purchased some that was too old, don't fret...have your children use them as a painting tool. All you'll need is some finger paint, paper and corn. This is a great texture lesson and will be fun for kids. This could get a bit messy so you'll probably want to do this in your back yard or on your porch. Putting a tarp down is a good idea too. You may want to get some skewers (you can smooth the ends by cutting off the pointy part and sanding the ends) and stick them through the corn as a handle.
