Cloud chambers are devices that can be used to observe the movements of alpha and beta particles as they pass through a supersaturated vapour. [please see links]
In a diffusion-type cloud chamber, the bottom of the chamber is cooled to produce a temperature gradient in which trails can be seen.
vapour condenses into droplets when disturbed and ionized by the passage of a radioactive particle. This produces a fascinating display. These devices can often be found at science centers.
I propose a poster-sized frame containing a vertical cloud chamber. This would make an incredible addition to any room and provide a perfect conversation piece.
Catering to the geek crowd, the piece should feature a smart brushed-metal finish and an LED backlight. An accompanying booklet would explain the basics of cloud chambers for the benefit of the less-than-casual observer.
Of course, the deluxe version also features shifting coloured LEDs with the option to add ambient sound.
The sound would be triggered by a particle detector and would thus match the display in a simliar way to a Winamp plugin.
Just picture a mini version of the 'tunnel of mystery' at the Chicago airport.
Remember to use a sturdy nail to hang your new frame.
Thank you for your feedback.
