Reminds me of the technical school I attended until last year... once a receptacle started pulling out of the wall (pretty common here since more often than not receptacles here are only fastened using claws that spread against the wall of the box and if the plastic box isn't all surrounded by plaster the box expands under the pressure of the claws...)... one day the receptacle was gone (backstabbed of course) and only the bare live wires were hanging out of the wall... 230V to ground. Stayed that way for about a week until it got fixed. Don't like the thought of something like that around nosy and potentially stupid 14-year-olds...
