In my post on the wrong kind of rain the other day I talked about how water is something that you can’t remove from the system. All other food systems can be broken down you get cows by applying two parent cows to a field and some hay and proving them with some water. And to get the grass they need the grass needs water too. It all comes back to water in the end. Water is axiomatic in a way.
There is another weird cross-over with water too in that it has traditionally been one of the most difficult things to deal with when doing special effects, because it’s the one thing that you can’t miniaturise. You can make an entire town at 100th the size and have a giant stay-puft marshmallow man walk around the city and when you show it on screen it will really look (well almost) like the stay-puft marshmallow man has come to New York. But the same isn’t true with water. To make a load of water run down a city street and look convincing you’ve always had to actually put a whole load of water in a street which is a tad expensive. Because the problem is that when you see some water running in the middle of a miniaturised set you can immediately tell that the water is too big. It just looks wrong, because you can actually tell that it hasn’t been miniaturised. You can see some examples of where they just decided to go with it in such movies as Die Hard 3 and one of the Indiana Jones movies (I can’t remember which).
Now of course cgi has ruined my point because you can shrink the water by the appropriate amount in the computer.
