Researchers at UCLA have constructed a machine that takes X-ray images using a roll of Scotch tape. When pulled apart, tape generates electromagnetic waves through simple friction. The researchers discovered in a vacuum, sticky tape also sends out strong enough X-rays to image your finger.
Pretty neat, considering getting your hands on some Scotch tape isn’t too hard. Imagine if giving yourself an X-ray were as easy as purchasing Scotch tape. It’d be X-rays for everyone! Unfortunately, it only works in a vacuum which crushes any hopes we have of DIYing our own X-rays. What a drag.
