Stinky Tracker Balls

These Orange balls are the ubiquitous anti-crime tool in Japan used for stopping all sorts of criminals in their tracks.

The balls are filled with a thick florescent ink that glows in the dark, and has a strong smell. Police dogs in Japan are actually trained to be able to track this particular odour (said to be similar to rotting pineapples), and are taught that it is the smell of a criminal.

The balls are available for about £6.50 each, and actually come in lots of colours. However, Orange - for some reason - is the only one that is in wide use.
