Unusual uses for ordinary things make life easier. Do you want to color wood, but don’t want to invest in stain? Try coffee! Need to do a quick load of laundry, but forgot to buy detergent? Use mouthwash! Want a cheap and easy alternative to dryer sheets? Believe it or not, tennis balls will do the trick! It is simply amazing what you can do with ordinary items that you have just sitting around your house.

Come up with the most unusual and helpful uses and you could win an iPad Mini 4. Sift through your pantry, dig through your closets, and sort through your garage to see what unusual uses you can come up with for everyday objects.

The Unusual Uses Challenge 2017 is closed.
