Is that real?

Many years ago...  I was young.  Life was simple in that TV and movie technologies were rather primitive. If something was trick-filmed it was fairly obvious that what was shown wasn't quite reality.  

Nowadays, through the miracle of computer generated imagery, anything can appear on a screen looking pretty life-like.  The other day, the TV was on with some kind of nature show. It was showing a volcano spewing lava into the ocean and Mathias asked me if it was real.  My first thought was "of course it is real. It's a volcano"... But how would you really know if you are accustomed to seeing talking cars, monsters, and flying houses on TV (none of that, by the way, is real)?

So yes, volcanoes are real. It really happens.
