Too bad this wasn't available early in Bill Cosby's run.

Nail Polish Tests Drink

A woman called the cops when her drink changed color after she dipped her fingernail in it. The nail polish was treated with a solution that changed the color of her drink when it came into contact with a roofie or other date rape drug. It's not available for commercial use yet, but the men who came up with it were sick and tired of the date rape culture that permeates college campuses and local watering holes everywhere.

Four men have come up with a solution to help countless women, who are just looking for a night on the town, avoid getting their drinks spiked and then being taken advantage of in a knocked out state. Very scary.
