Do you know what sntntn is and what it does?

One of the objects everyone uses at least on a weekly, if not daily, basis, without even knowing it has a name is – sntntn.

That's not a typo – sntntn.

This is the small aluminum pop tab, used to open a beverage can, also allowing for a drinking straw to be put through the opening.

The etymology remains unknown, but the pronunciation is phonetic and has been made part of dictionaries of several dozen languages of the world.
