Why does sticky tape make that horrible screechy noise?

Have you even been wrapping a present or getting crafty and heard the terrible screech of the tape you're using?

Well scientists have now discovered WHY it makes that horrid noise, after decades of study.

The research team used high-speed cameras and microphones to capture tape as it peels away from the roll.

So what did they discover? Read on to find out.

Writing in Physical Review, the research team discovered that when the sticky side of the tape peels off the roll, it doesn't happen evenly but tears in narrow bands.

These micro-cracks travel sideways along the tape at supersonic speeds, and when they reach the edge of the tape, generated a sound pulse or a mini sonic boom.

Which of course, is the screeching sound!

Do you hate the sound of screechy tape? What other sounds send a shiver down your spine?
