X-Ray DIY with Scotch tape and a vacuum

Okay, so not everyone had a vacuum (and I’m not talking about the upright in the cupboard you use once a week to clean the carpets) available – but almost everyone has a roll of Scotch tape lying around. Apparently the effect of peeling of a piece of Scotch tape from the roll (when enclosed in a vacuum) releases enough X-rays to image a bone in your hand!

This kind of energy release — known as triboluminescence and seen in the form of light — occurs whenever a solid (often a crystal) is crushed, rubbed or scratched. It is a long-known, if somewhat mysterious, phenomenon, seen by Francis Bacon in 1605. He noticed that scratching a lump of sugar caused it to give off light.

Believe it or not – go take a look at the Nature website to read more.
