A new line of drinks-coasters will change color if a beverage containing any of several date-rape drugs it placed on them.
Drink Safe Technologies in this Fort Lauderdale suburb is hoping liquor manufacturers will buy licensing right for the coasters, put their logos on them and distribute them in bars and clubs.
Company co-owner Francisco Guerra said the coasters can detect predator drugs like "roofies" and "liquid ecstasy," protecting potential victims.
