How to: Wash out inside of cans while keeping the wrapper untouched. Have kids use a nail and hammer to make small drain holes in the bottom of the cans. Fill with seed starter, potting soil, or dirt from the yard. Plant a few seeds (you can thin later) in the correct store labeled can. We did green beans for green beans, tomatoes for diced and stewed tomato cans, pinto beans for Ranch Style bean cans, and peppers in a Rotel can. Place in a tray or saucer (to catch water from the drain holes) and place in a sunny window. Water carefully with a turkey baster. When they grow to size, you can plant them in your own garden or give as a gift to a friend.
