odd question, but could really use the advice

...i figured this was the best place to ask.

i am shooting a movie in which i need it to "rain" inside of a house. my best idea so far, besides a hose or a sprinkler system was rigging up a soaker hose or a drip tape to allow it to look like rain.

my question is...will it "drip" very fast or really slowly? even if i have all 25 feet in one area...also...if i had high water pressure in a soaker hose for example, would it rain "faster" than if it had low pressure?

any advice would be great.

Depends on if you want a gentle,heavy or light rain. Can't be sprinkler...like pop-ups for lawns because you'd probably be able to see the circular pattern of the drops,soakers would just drip....maybe the flat type hose/sprinklers w/holes punched at intervals....or even a mister?

Sorry ,female in me kicks in and wonders whose gonna clean up the mess afterwards....LOL

eHow says This rain machine is easy and inexpensive to make.

Directors commentaries on movies on DVD usually avoid the subject but those who do speak of it say there is no good substitute for real rain.

you could try a drip irrigation system with varied emitters in the hose. You start with a solid drip irrigation hose and then buy some 1/2 gallon per hour emmitters some 1 gallon per hour emitters, some 2 gallon per hour emitters etc. this would give you diffenent amounts coming out of each emitter. I don't know if the drops are bigger or if they come more frequently on the 2 gallon emitters. just a thought. Good luck

Adjusting the water pressure on a drip irrigation system is relatively easy by using a pressure regulator on the spigot. Most soaker hoses come (in the ones that I have anyway) with a blue round rubber pressure regulator in the female end of the hoses. The blue regulator has a hole in it that acts like a regulator. If the current hole doesn't produce enough rainfall, drill it out and make it larger. Then again, you could regulate the amount of rainfall by adjusting the flow out of the spigot. Just a few ideas.

RE: odd question, but could really use the advice

Most of the soaker hoses I've used, the higher you turn up the water, the more the water tends to shoot out in direct spray jets from the myraid slightly-larger-than-regulation holes that there tend to be. If that makes any sense at all. I've had some success in the past rectifying this by covering said holes with electrical tape, but there are usually quite a few. Hence, your 'hard rain' would be interspersed with tiny shooting jets of water in various spots. Also, in my limited experience, water coming off of a soaker hose tends more to run down the length of the soaker hose and eventually drip off, rather than falling in neat, patterned 'raindrop' style drips. Though I admit to never really observing it in an elevated state with this thought in mind.
