...for detection of melamine in milk. Guaranteed to be sure winner as the PRC government can't seem to get a handle on the scandal, or the chemical additives in their dairy products. -what? http://news.bbc.co.uk/2/hi/asia-pacific/8443437.stm My idea would be a device similar to a urine pregnancy test, but using a few drops of Chinese sold milk instead. I'm sure that people all over China would buy it as the safety of their kids are their top priority.
^ i'd definitely invest in that. As long as the product was cheap for the end user. Chinese people would rather risk it and die than spend alot of money on a melamine detector.
But the most important thing of all? It would finally take the matter out of the governments hands and put power fully with the Chinese consumer; it would essentially put those baby killers out of business.
