A recent article in Science News reveals an amazing tape fact. The simple act of unwinding a roll of tape generates X-Rays. Not just a few random rays-enough to actually expose a piece of dental x-ray film!
Scientists at UCLA were able to build a simple tape unrolling machine that generated enough X-ray bursts to actually image one of the technicians’ finger bones on an dental photographic plate.
This phenomenon is not completely understood nor is apparent that there is any commercial application for such technology. A charge is generated when the tape is peeled off the roll. Sudden jerking of the tape seems to cause electrons in the tape to give off energy in the form of protons. A slight glow is even generated.
Next time your flashlight batteries go dead, maybe you just need to unwind (really quickly) a roll of duct tape.
