Four North Carolina State University students have reportedly developed a line of nail polishes that can change color on contact with date-rape drugs such as Rohypnol and GHB. The product is still in testing, but the students plan to sell the nail polish as Undercover Colors, “The First Fashion Company Empowering Women to Prevent Sexual Assault.” The students won a university entrepreneurship competition with their product in spring 2014 and are raising money to fund its wide release. “Through this nail polish and similar technologies, we hope to make potential perpetrators afraid to spike a woman’s drink because there’s now a risk that they can get caught,” the students said.
