Mystery Device in Teen's Room Turns Out to Be Surprisingly Common

Found this strange little white device in my 16-year-old son’s room, and I’m honestly too embarrassed to ask him what it is.

At first, I thought it might be one of those new USB sticks kids use for school. It was small, white, plastic, and shaped almost like a tiny flash drive or some kind of charger part.

But when I picked it up, I noticed it did not have any metal plug, no charging port, no button, and no obvious label. One end had a cap-like bottom, and the top had tiny little holes in it.
