This is ULTRA cool. Some dudes at University of California have used SCOTCH TAPE to make XRays of their hands.... apparently from some Soviet finding in the 50's (how many of these things are old soviet discoveries these days!!)
From the article: " SCOTCH tape is not only see-through, it can also "see through", for the product can be used to take X-rays, bemused scientists say.
Peeling tape from a roll of Scotch releases tiny bursts of X-rays that are powerful enough to take images of bones in fingers and hands, researchers have found.
The unusual discovery was made by a team at the University of California in Los Angeles. They were intrigued after hearing that Soviet scientists in the 1950s found that sticky tape, when separated at the right speed, released pulses in the X-ray part of the energy spectrum. "
