The London South Bank University got a new pub, and the drinks are free!

The catch is that they may or may not actually contain alcohol. Oh, and it's not a real pub. In fact, it's got little cameras all over to track your every move.

This new pub, J-407, is actually the university's latest psychology lab built with a budget of £20,000. Psychology students are the bartenders, and CCTV cameras hidden throughout will be used to study how people get drunk and interact.

But here's where it gets a bit weird and interesting: the pub's soundtrack will play music, AND pre-recorded chatter to fake the actual ambiance of a pub. The glasses are rubbed with ethanol, so the pub smells like a real one.

The entertainment at the bar also double as research props. According to the Guardian, "Props include a fruit machine, to test risk-taking behaviour, and wire loop games will test eye-hand co-ordination. There will, eventually, be a juke box to determine what kind of music makes people drink more quickly."

This brings us back to the beers, which will contain unknown amounts of alcohol to study how it affects patrons/subjects. Of course, since it's psychology research, the pub won't get people drunker than the legal driving limit - which is odd considering they should be studying true drunks.
