Like many students, their dorm rooms are suite style, so they have semi-private bathrooms which they have to keep clean.
(The money we're paying ... and he has to clean his own bathroom?? Yes, I know, I thought the same thing.)
Anyhoo, each teen bought a plunger for their toilet.

This is what my niece bought. Isn't it nice? It has a tasteful storage cover so it looks good in the bathroom. She's a stylish gal.
This is what my son bought.
Yes, that's a plunger. I had never seen anything like it. But my son, a veteran of many years of Boy Scout Camp, assures me that it can plunge anything.
I think he's going to do very well at college.
