Once I finish a powdered drink (Advocare Spark) tub, I save the scoop and use them as measuring spoons. One scoop is ~1 Tablespoon. They are perfect for measuring out things like salad dressings, sour cream and Cream of Wheat or whatever you can imagine.
P.S. Most High Efficiency Side loading washing machines you only need 1 or 2 Tablespoons of laundry detergent. You could use the scoops to measure out the detergent and you'll be amazed at how much longer the bottle of detergent lasts!
