Anti pint-theft device

Steal this beer glass at your peril.

Have you ever been enjoying a pint and found yourself admiring the glass you’re drinking from, perhaps so much that you’d like to keep it.  The folks at Sweden-based Kopparberg claim this is a problem they’ve been having since introducing their new pint glasses. So they’ve developed a black tag (which reads “I know it rocks, but please don’t steal it”) that’ll explode ink over a patron should they take the glass 100 metres from the bar (probably not the souvenir they were counting on). Talk about a messy night, not to mention one you wouldn’t be able to forget for a while.
