It appears your Mom was right. There really is nothing between your ears. At least, when you're wearing these earrings, it will look as though there is a rift between your left and right ears through which a tiny test subject can travel.
This pair of silver-plated enamel earrings is a must-have for any Portal fan with pierced ears. Only have one ear pierced? Give the other earring to a friend and then you'll have an instant conversation starter! Mainly though, we expect these earrings will be worn by people with two ear holes, thus making it look as though a test subject is leaping straight through your head.
