When Ray Lockett's 21-year old daughter Marilyn had a drink spiked with a heavy sedative earlier this year, he decided to do something to help prevent this kind of abuse. He invented the Spikey- a bright glow-in-the dark bottle stopper that is inserted by the bartender and cannot be removed, leaving only a straw hole for sipping. Lockett hopes that the bright, conspicuous appearance of the Spikey will also make it difficult for anyone to furtively spike a drink in the darkness of a bar.
Something could still be poured through the straw, I think, so you should probably keep a drink detective handy too. Better still, buy your own drink, and keep your eye on it.
