What does spiritual science tell us about the phenomenon of capturing ghosts in a bottle? Is it possible?

Recently the news of two ghosts captured in glass vials with stoppers and soaked in holy water captured the curiosity of world media. The ghosts were reported to have been not only captured, but also sold at an auction in New Zealand for almost $2000. There has been subsequent debate on whether the captured ghosts were for real.

This is not the first time that sale of ghosts in a bottle has caused a bit of a stir. A few years ago a mill-worker from North Ireland set up a similar sale on eBay, and one man in Florida has even set up a business of selling ghosts in bottles which are captured by professional ‘ghost catchers’ around the US.
