Can sticky tape make X-rays?
Correlation between nanosecond X-ray flashes and stick–slip friction in peeling tape
Peeling sticky tape in a vacuum gives off enough X-rays to take a picture of a finger bone.
Physicists unrolled ordinary sticky tape inside a vacuum chamber and measured what came off as it peeled.
Each jerky little peel released a burst of X-rays, enough to make an X-ray image of a finger. Do not try this at home, partly because you probably don’t own a vacuum chamber.
Sticky tape: secretly a very small particle accelerator.
