Date Rape Drug Spotter

Inventor: Francisco Guerra

Singles bars have never been risk free, but so-called date-rape drugs give you one more reason to be cautious. After a friend was attacked by a man who may have spiked her drink, Francisco Guerra developed a cardboard drink coaster that can identify two of the most popular date-rape drugs: gamma hydroxybutyrate (GHB) and ketamine. Just place a drop of liquid on the coaster, and rub it in with your finger. If the spot turns blue, toss that cocktail. Fifteen million of these coasters have already been distributed; look for them at 7-Elevens around Christmastime.

Availability: Now, 40 cents a coaster
