Imagine this: Your in an heated, but airless doam (sp?) on the moon, with 20 min of air on your back. You have a CPS 2500, and a WBL. You see the enamy 150+ feet away. You turn the 2500 to 20x, pump it half way, and pull the trigger. Because drag doesn't exist, the stream keeps together perfectaly, and the 1/6 gravity factor makes for a long range stream. Then you see the commander of the enamy forces. He is around 1000 feet away. You fire the wbl, but hear nothing in the airless enviroment. The balloon never looses speed, and keeps on going untill it hits the unexpecting commander. Is that nice, or what?

How can it be a heated but airless dome? Heat is the vibration of particles but if there aren't any particles as there is no air then there can be no heat.

That would be pretty cool though. But the enemy could probably dodge before the stream or balloon reached him.

Not with the acceleration that comes in a airless enviromen. no air resistance therefore increased accelearation and velocity. in a vacume you cant heat it but you can hit yourself with infa-red waves.

Dose of reality:
no air means no streams: you need air pressure to keep your streams as water. Without air pressure, the water will boil off into space.

The 1/6th gravity would allow your streams to travel farther, though, but they would still experience some (though very minor) air resistance.

Since you'd need air, you can ditch the air-tank on your back in the dome. Also, since it is air, the dome can be temperature regulated.

The speed of streams is limited by the pressure and nozzle size a soaker has. Streams would go no faster than they do on Earth.

The high jumps and longer ranges would make a water fight cool. Push the fight into a space station and you wouldn't have to worry about streams arcing downwards. The biggest problem, though, would be all the water that would end up clinging to everything everywhere afterwards.

Someday someone will create some sort of low gravity environment that people will pay admitance to get into (bendind laws of pahysics perhaps). That "someday" will be the day one could have water warfare these special effects. I think that water warfare in a low gravity environment will come before water warfare on the moon because space exploration probably won't have major forms of recreation until a reasonabel portion of humanity is in outer space.

What I ment for the wbl is to go to a special compresser that has air inside it, so all you have to do is plud the wgl in, and flick a switch. :cool: And bunny? How do you think the suns heat gets to Earth? The same way it gets to a player in the doam.

Unless the balloon is really strong, it, too, will burst if you push it from a pressurized chamber into a vaccuum. If the water-filled balloon is strong enough to survive a vaccuum, it won't burst on impact, then.
As for baking people in infrared light, I'm not sure players would like that. If the entire game were occurring in a vaccuum, players wouldn't just need air tanks; they would need entire spacesuits. (People in vaccuums have outer blood vessels in the skin burst even if they have an air supply to let the breathe.)
Low "g" water-fights would be sweet, but leave the air in place! :cool:

Also a true vacuum is almost physically impossible to achieve. Not to mention the fact that it is very cold at 0 Kelvin or -232 degrees centigrade I think. Plus light can not travel through a vacuum and the nearer you get to a true vacuum the slower light travels (in fact a few years ago some people made an almost vacuum and measured light travelling through it at 32 mph I believe it was.
Well actually I think you mean me (we have the came avatars). The sun's heat gets to Earth as radiation. If you were exposed directly to that radiation you would ultimately die. Luckily we are protected by the atmosphere which is heated by the sun and in turn heats us.

Its a rather cool fantasy, however the exact opposite would happen to what you are thinking. If its heated thats fine, but the current gravity if earth can make a CPS 2500 shoot 40 feet. 1/6 of that and you have about 15-18 feet. Since the gravity helps to control coherency, you will get more of a slug shot on the moon, with 1/6 the coherency of the stream on earth. If the moon had twice the gravity of earth, it would be possible guns could not shoot, due to so much stress on them from the gravity.
its also possible some blasters wont work on the moon. Since water guns need to compress air to shoot, there is no "air" to com[ress it with. All that air is in a tank supporting your life up there.

There is one disadvantage of a CPS 2500 (or any medium-to-large CPS) being used on an area with 1/16th the gravity of the Earth. Quite simply,

"Every action has an equal and opposite reaction."
-Newton's Third Law

I can just imagine you trying to control the spray as you're flying backwards towards the dome. :D

It would also be true that with enough force a WBL could quite literally knock someone into the air.

Wrongo! :goofy:

Suppose that you can shoot water normally on the moon (which you can't).
The force will not knock you backwards that much. A CPS-2500 is not that powerful, and the moon's gravity is stronger than you might think.

Well the gravity on the moon will stop you from flying backwards though the kickback will be slightly more. Even if there was no gravity the mass of you compared to the mass of the water stream would mean that you still would not go fyling back very much.

In that case the Earth is basically the perfect place to have water warfare and any dramatic range or power enhancement will have to come from some other man-made means. More pressure and a larger, more coherent stream rather than reduced gravity will give you a stream similar to theoretical streams on the moon discussed here. Otherwise, I'd imagine that some theme park owner will create an attraction simulating water warfare on the moon eventually.
