You would think it's a trick question, but it's not. The answer is: car parts!

Let me clear up the confusion you must be feeling right now. Ford and Heinz are teaming up to research the possibility of making car parts with the scraps left after making ketchup.

Seriously.

Dried tomato skins are, at times, very durable and may be the perfect material to make wiring brackets or cup holders or bins. There are several possible parts that are being looked into.

Don't get all excited, the project is in its infancy, so even if parts are successfully produced (get it? produce-d??) we won't see them on the market for at least a few years. Still, cool idea!
