For a long time after my daughter was born, I wasn't sure if she could hear or not. I tried to get her to react / turn her head / wake up to voice, music, claps... Nothing.

One day I was taping up a box behind her and I pulled out a length of packing tape. It made that awful screeching noise and she was startled. It was a repeatable result. Her hearing was fine, she was just super chilled about noise in general. I found her limit with a roll of tape.

That’s really cool. Scotch tape is just weird, peeling it also generates x-rays (in a vacuum):

"The screeching of peeling tape is a familiar albeit annoying sound."

I don't find it annoying, I quite like it. The only time I've experienced "ASMR" was from somebody peeling tape next to me.

Scotch tape just keeps on giving in science.

I remember buying the Scotch Magic Tape, the matte one.

I was surprised that it didn't make the sound. Probably because it's a little bit more flexible?

This was a surprisingly satisfying and interesting read. Cool setup and delightfully random but well answered question.
