Drink Savvy, a Boston-based company, has created a material that changes colour when it comes in contact with a drug-spiked drink.
Founder Mike Abramson said he plans to use the discovery to create a set of products, including cups, glassware, stirrers and straws, that he hopes will be used to help reduce date rape, reports ABC News.
"Within the past three years, three of my very close friends and myself have been the unwitting victims of being drugged," Abramson said in a fundraising video.
