Anti-roofie beer-lock
A Welsh inventor has created a tamper-evident beer-bottle seal that women are meant to put over their drinks while they're in the toilet, as a means of foiling date-rape-drug dopers.Link (via Engadget)The plastic cap fits on the bottle and locks when a small 'key' is pulled from it.
When the drinker returns from the bar or toilet, it can be unlocked and a red warning light on the top of the cap lights up if anybody has attempted to remove it.
