I'm currently living in my first apartment, and I'll be moving out soon. I've got tons of scuffs on the walls from stuff like installing my furniture while moving in and bringing my bike in and out of my apartment. I tried cleaning them with soap and water, but they weren't budging at all, so I sighed and resigned myself to losing my deposit. I mentioned it off hand to my dad recently, and he told me to try using a magic eraser. I was a little skeptical, but I went out and got one anyway. I was amazed, literally one swipe of the eraser was able to get rid of the smaller marks instantly. My walls have never looked better!
I had always assumed magic erasers were just sponges with some soap already inside them, maybe with a scotchbrite pad attached. But I looked it up, and no, the "eraser" in the name isn't metaphorical. They work exactly the same as pencil erasers. They're super fine plastic sponges, and when you rub them on the wall they break down into tiny sharp plastic fibres which act as an abrasive. I found that super interesting to learn, and now I have another tool in my toolbox.
I've always used this version, since the verb is commonly used in modern English unlike buffalo:
Police police police Police police police Police police.
That expands to "the police from Police, Poland will police the police from Police, Poland, who in turn also police the police from Police, Poland" or something like that.
