If you wear makeup, you probably go through a few tubes of mascara a year. When you finish one, you probable toss it and get a new one.
But before you throw out any more, you might want to think about 'recycling' the wand.
Thanks to the Appalachian Wildlife Refuge in North Carolina, people are learning how their old mascara wands can be used to save wild animals.
You might not have considered it, but those little brushes work so well on the fur of vulnerable, little wild animals.
