These days physics often seems far removed from reality-black holes, worm holes, particles being in two places at once, 10 spatial dimensions. So its a pleasant surprise that physicists at UCLA have found a new dramatic application for the scotch tape in your kitchen drawer: generating x-rays.
When the tape is peeled removing the adhesive-electrons are released generating electric currents. In the photo to the left you're seeing visible light emission from these electrons. It turns out they also emit x-rays, so many that its possible to x-ray a human finger. I was about to try an experiment and x-ray my painful tooth but that's on hold because apparently you have to do this in a vacuum.
OK here is the kicker-physicist Seth Putterman says the process could be used for nuclear fusion. I'm a bit skeptical about that given the history of table top fusion attempts so far. You can read the details here:
