    Just find some politicians; the only trick is getting the tape inside their skulls.

    Just bring it close to their ears; the vacuum will draw it in.

      but why doesn't it work outside of a vacuum? Clearly this limitation is a problem the makers of scotch tape need to address! :D

        Wow that's really interesting. Who'd have thought that peeling tape could generate something as energetic as x-rays?! Now to find a vacuum pump and lots of scrotch tape for cheap, muahahhhahahahh..

            Ever tried peeling open a self-seal envelope in the dark? Watch the glue!

              Because the x-rays are emitted when they hit the other side of the tape and slow down dramatically. Without a vacuum I would guess that the journey to the other bit of tape is slowed down due to ocassional collisions or deflections and so there's not eneough energy to emit an x-ray. Just a guess

              cheers, Chris Maunder

                      Too late...the scientists who discovered it are already preparing a patent application...and, unlike software patents *spits* this one will have NO questionable qualities.

                        The tape is not radioactive (the decay of unstable nuclei) - the tape strips electrons from one side of the tape and collects them on the other. This builds up a potential difference between the two sides. If the potential (voltage) is high enough some electrons can be coaxed into jumping from one side to the other. When the electron gets to the other side it can be deflected (turned) and slowed by an atom or it might knock an electron loose from an atom. In the first case the energy lost by the slowing electron is given up as a continuum of x-rays called Bremsstrahlung Radiation. In the second case x-rays at specific energies related to the atom that lost the electron can be generated. The author doesn't state the range of energies the x-rays have when generated in vacuum. If the energy is below about 2000 eV then the x-rays are readily absorbed in air, and hence the need for vacuum in order to detect them. It may be that they are produced but not detected in air. In order to get x-rays with useful penetrating ability you would need energies in the 50,000 eV range. In air the charge that builds up may be readily dissipated so that no electrons jump, and thus no x-rays.

                          I could easily see the reinstatement of the star wars program from this finding. No one would suspect a giant roll of scotch tape to have a lethal potential. As a matter of fact maybe space programs could start stockpiling tazer tape in outer space now for "construction purposes" hehehe. :laugh:
