Large pole with computer controlled vibrating tip. When held to a pane of glass, it weeps through frequencies until it finds the natural resonating frequency of the glass, alerting the pole-bearer, who can then turn up the energy, thereby shattering the window.
If that fails, pole can be used to smash in window.-- Cuit_au_Four, Apr 18 2006 Just so long as you make it look like this. http://mlb.imageg.n...MLB2-1469581reg.jpg [Letsbuildafort, Apr 18 2006] Structure sabotage Structure sabotageSee this for a more advanced implementation of the same concept. [snus, Feb 15 2008] //weeps through frequencies// A crying shame. Also, a single light tap would cause the glass to resonate at its natural frequency, which could be measured.-- Ling, Apr 18 2006 folds up and slips neatly into a pants pocket.-- po, Apr 18 2006 Only for glass? I want to be to wave it around dressed in a silly wizard costume, and it to cause things to magically happen with harmonic frequencies. +-- dbmag9, Apr 18 2006 I've got two for you: 1. The guy with a 15ft pole inside a 9ft house that manages to not break the window, and 2. The choir singer from Krakow that keeps singing out of key.
You choose.-- methinksnot, Apr 18 2006 Again, it seems to be the Halfbakery's unofficial motto: The $100 idea over the $10 solution. Louisville Sluggers on sale.-- Letsbuildafort, Apr 18 2006 Such a pole could be used to find the resonant frequency of a large solid non-glass object - for example, the Washington Monument or Ayers Rock. The object should then vibrate sympathetically and loudly. One could then use a microphone attachment to convert spoken words or music into permutations of the resonant frequency, and use the object as a giant amplifier.-- bungston, Apr 19 2006 You gotta love self-adjusting resonators.-- DesertFox, Apr 19 2006 And where would you carry such a device? You would want easy and central access to it with either hand. Perhaps behind a zipper, or buttons.-- Galbinus_Caeli, Apr 19 2006 One possible problem. I suspect that most objects will change their resonant frequency slightly as the amplitude increases.-- MaxwellBuchanan, Feb 15 2008 random, halfbakery
