A nail polish that changes color on contact with GHB
Four students from Duke University in North Carolina have found an ingenious way to detect date-rape drugs. They created the nail polish range Undercover colors that changes color on contact with Rohypnol (flunitrazepam), Xanax or GHB. The use is very simple, if a girl wants to check if her glass is safe she just has to discreetly dip the tip of her finger in it and thus detect if someone has put an illicit substance. It is frankly a good idea, and I encourage this project. Having known victims of this drug / sexual predators, I hope this project will be successful!
