A simple coat of nail polish could soon prevent Kiwi women from falling victim to date rape.
Four United States students have created a nail polish that changes colour when exposed to date rape drugs, and support for the product is growing in New Zealand.
Undercover Colours was developed by University of North Carolina undergraduates Tyler Confrey-Maloney, Stephen Gray, Ankesh Madan and Tasso Von Windheim.
They are now fundraising to get further testing carried out with a view to getting the varnish on the market around the world as soon as possible.
"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," Mr Madan told the Daily Mail.
