New device can detect date rape drugs in your drink

A new pocket-sized device that can test your drink for common date rape drugs in a jiffy has been developed.
The gadget, called pd.Id, or the "personal drink ID", can be dipped into your drink, and it will scan for colour, conductivity and temperature.
It then takes that information and compares it to a database of drinks it knows by connecting to an app on your phone, 'Huffington Post' reported.
If the drink contains only red wine, a green light will flash. But if the device spots a common date-rape drug like Ambien or Rohypnol, a red light will flash.

David Wilson, a former IT consultant living in Toronto, began working on pd.Id three years ago. Since then he has launched a campaign on Indiegogo to raise USD 100,000 to fund his project.
The device can't pin down exactly what's in the drink but it can still act as a "warning system".
However, Wilson admitted that things such as dishwasher soap residue could interfere with the results provided by the gadget.
