if you peel the popular adhesive tape off its roll in a vacuum chamber, it emits X-rays. The researchers even made an X-ray image of one of their fingers.
Who knew? Actually, more than 50 years ago, some Russian scientists reported evidence of X-rays from peeling sticky tape off glass. But the new work demonstrates that you can get a lot of X-rays, a study co-author says.
"We were very surprised," said Juan Escobar. "The power you could get from just peeling tape was enormous."
Escobar, a graduate student at the University of California, Los Angeles, reports the work with UCLA colleagues in Thursday's issue of the journal Nature.
Cooooooooool.
