Bomb-Proof Toilets Coming to Russia New concrete johns will be nigh indestructible By Kevin Spak, Newser Staff Posted Jun 9, 2011 11:53 AM CDT 11 comments Comments Symbols of public toilets and warning 'Do not go inside on roller skates' are posted near the Kremlin in Moscow on November 17, 2010. (Getty Images) (Newser) – Take comfort, tourists: Russia's public toilets will soon be bomb-proof. The country plans to roll out some nigh-indestructible über-johns by the end of the year; they'll be made of fibrous concrete, with fittings fashioned from a mixture of steel and heavy-duty plastic, CNN reports. “If somebody will leave a bomb inside the lavatory and it explodes, the toilet won’t be destroyed,” an official involved in the project boasted. But that’s not the only cutting-edge security feature coming to Russia's revamped, high-tech public bathrooms. The facilities also limit occupants to thirty minutes on the john; after that, the doors will swing open and an alarm will sound. Doesn't that make you feel safer already?
