Fun fact #1

Now we all know what this is, isn't it? It's a small plastic covering at the end of shoe-laces. But do you know what it's called? An aglet. Yes, a small name that is, for a thing of such usefulness. If it weren't for this aglet, your shoe-laces would have un-wound themselves even before you could get your shoes tight.
So the next time you are referring to one of these, use the term. Aglet.
