Four undergrad engineering students at NC State University have created a new beauty product that could save your life, or help protect someone you love.

Tyler Confrey-Maloney, Stephen Gray, Ankesh Madan and Tasso Von Windheim created a nail polish that changes color when it comes into contact with drugs such as Rohypnol, Xanax, and GHB in an effort to protect women from date rape drugs.

The students said, "We were thinking about big problems in our society, the topic of drug-facilitated sexual assault came up. All of us have been close to someone who has been through the terrible experience, and we began to focus on preventive solutions, especially those that could be integrated into products that women already use. And so the idea of creating a nail polish that detects date rape drugs was born."

To activate the polish, a woman would just have to discretely stir her drink with her finger tip. If the drink has been drugged, the color will change.
