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.

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.

Scotch tape just keeps on giving in science.

Can also be used for apple biting sound effect
