Have an empty Yoplait Smoothie bottle, a Land-O-Lakers spreadable butter container, and an X-Acto knife? Then put all three to good use by making a functional hummingbird feeder. Just cut two nectar port holes (diameter of a pencil) at each end of the butter container lid, carve a hole in the center (smaller than bottle top), push the top of the bottle through, and then attach zip-ties to hang it. Video after the break.
