ANSWER: Food

White layer under the peel


An orange peel sticks to the fruit because it's "glued on" by white fluffy stuff called albedo. When you've peeled an orange, you've probably noticed how hard it is to get every little bit of this white albedo off the outside of the orange slices. If the albedo weren't there, the peel would just fall off the orange.
