I'm a bit of the a silent movie fan.I am sorry, I call Shenanigans on this one.
First off I'd like to say that I am a film student, and have been studying this field since the 4th grade. So you know I'm not just pulling random stuff out of my arse.
The first publicly released motion picture wasn't recorded till 1907, and it was recorded by Edwin S. Porter. It is true that before 1907, the french had experiments with moving pictures, but these trials were interpreted more as "home videos", the most memorable of which was a kid eating a plate of spaghetti.
Although this horror movie claim may in fact be the first of it's kind, the reported release year is way off.
Water in copious amounts taken in a short span of time can do this to you as well and a radio station in the midst of a concert promotional stunt found out a few years back the hard way. A listener died after chugging several gallons of water in a very short number of hours. I don't remember the station I.D. but it made big news headlines in the Midwest of the United States and a lot of radio stations stopped the performance of ticket givaway stunts by listeners afterward.100% chemically pure water can kill you.
