Thinking about changing the field …X-rays from Sticky Tape

Ever heard about X-rays from sticky tape … never!?
There you go … its a new field! Still there has been a publication in Nature about exactly this subject.
Some of you might have seen light being emitted when pulling sticky tape, but these physicist could show that there is quite some X-rays comming out of these little bastards …
For everyone interested heres the publication:
“Correlation between nanosecond X-ray flashes and stick–slip friction in peeling tape”, Carlos G. Camara et al.; Nature, Vol. 455, S. 1089 (I cannot put a link due to copyright reasons)
There is a video showing the whole thing though!
