From The Verge: Crowdfunded cups and straws quickly detect ‘invisible’ date rape drugs - The odorless and tasteless nature of “date rape drugs” can make them impossible for victims to detect before it’s too late. But soon your drinking glass may able to warn you if dangerous chemicals have been slipped into your cocktail. Next month, DrinkSavvy will begin shipping plastic cups and straws that change color if a drink contains GHB, Rohypnol or Ketamine, three drugs commonly used for spiking purposes. The effort began with a successful $50,000 Indiegogo campaign led by company founder Michael Abramson — who himself was once unknowingly “roofied” during a night out with friends.
