Date rape is a serious problem that can be tricky to stop. Sure you could watch your drink like a hawk all night, but realistically it's almost impossible to tell when some creep has spiked your drink with a date rape drug. One solution is this specially treated glassware, which clearly warns you if someone has been fooling around with your beverage.
DrinkSavvy was developed by a professor of chemistry at Massachusetts' Worcester Polytechnic Institute to detect the three most common date rape drugs, GHB, Ketamine and Rohypnol. Whenever one of the three drugs is mixed into a drink, the treated area will change color from clear to red, warning the drinker that they've been slipped a mickey.
In addition to glasses, the DrinkSavvy technology can be built into straws, swizzle sticks, or any other surface that's going to contact the spiked drink. DrinkSavvy is currently raising funds on Indiegogo to develop the products, starting with disposable plastic cups and drinking straws. Eventually their plan is to convince bars and clubs to use DrinkSavvy equipped glasses for all their drinks, making customers feel safer about drinking there.
