Scotch tape emits x-rays when peeled off glass

More than 50 years ago, Russian scientists discovered that simple Scotch tape emits x-rays when peeled off glass. New research conducted by colleagues at UCLA has determined that the power that the tape generates is much higher than anyone could have imagined. In fact, they have constructed a machine that generates x-rays by peeling up Scotch tape in a vacuum at the rate of 3 centimeters per second. As you can see in the recent demo they did for the journal Nature, their device was able to successfully generate an x-ray of a finger.
