Orange balls and Japanese banks and convenience stores

Here is a simple idea that could only work in Japan. Most banks and convenience stores have orange balls near the counter so that if anyone tries to rob them, they throw a orange ball full of fluoresence ink at them. This then makes it very easy for police and others to spot them.

Watch this video to see how it works.



Are they still common in Japan? Please leave a comment if you know, or if you have ever seen one.
