The Watergate is a design by Michael Tatschl, Sascha Mikel and Martin Schnabl that would replace turnstiles with a different solution when it comes to keeping people out: water jets. While it doesn't present a serious physical barrier, it does allow for both the handicapped and people lugging around bags and bikes to pass through easily. All others? They get drenched.
Still, it seems like I could just walk on through whatever the Watergate is trying to protect if I thought ahead and wore my swimsuit. Then again, it'd be easy for officers to spot the drenched man in the crowd and stop me. I'd still sue for the gate killing my cellphone, though. Hurrah for frivolous lawsuits.
They should really just make this thing spit acid.
