Picture of How to Make a Rain Machine
How do you add instant drama to your scenes? Rain and sappy music of course. Using some wood, rope and a garden hose Erik shows you how to make a Hollywood rain machine for less then $50 bucks. Be sure to send in your Indie Filmmaking projects to Indy Mogul, and subscribe to our iTunes podcast!

Hey everyone and welcome to the technical blog for Episode#13 (rain machine). All you people who wanted a cheap way to recreate good looking "movie rain" read below. The coolest thing about this project is you probably have a lot of the parts laying around the house. Remember you can submit your project ideas here!

Warning: I'm using power tools to build this project. Always have adult supervision when using power tools if you are under 18. Seriously people be careful.

Shopping List

1. 25-50ft garden hose.
(I bought a 50ft one, but the water only came out about half way. I'd try a 25 footer)

2. Some cheap wood.
(I got about 20ft of 1"x2" beams. If you have some old 2"X4"s laying around just use those.)

3. Cable ties.
(I used these to fasten the hose to the frame. You could use duct tape in a pinch.)

4. Plastic Hose cap.
(This was like a dollar and screws on to the end of a hose to cap it off.)

5. Female to male hose adapter.
(This is a simple piece that allows you to screw the end of one hose to the beginning of another. Mine came with a nifty valve.)

6. 4 eye bolts.
(To provide a good place to hang ropes.)

7. Rope.
(I used some left over nylon rope I had from the samurai armor, but whatever you get make sure it is strong enough to support the rig. You don't want this thing falling on your actors.)

8. Some screw, nuts and bolts.
(Basically something to hold the frame together. I used wood screws.)

Did you just hook the hose up to a tap? I'm trying to find a way to do a smaller version of this indoors. I want the rain to fall into a collection area (like a kid's pool or something), then pump the water back up into the hose. Ideally I'd want it to have a variable control so you could turn a potentiometer and the "intensity" of the rain would change, but I don't know much about pumps. Can anyone help me out?

um dude the sun is shining tin the top photo??!?!?!?!?
 I've been in rain while it was sunny.. its not impossible. lol
i did this using pvc pipe and two Water inlets with a tap so i could adjust how much rain How powerful and the heat of the rain!!

I'd suggest that it would be better to make it more rectangular, since: 1) if you allign it perpendicular to the way the camera's pointing, you will have "rain" in a narrow strip. A lot of movement on camera is side-to-side and not towards/away anyway (unless you're specifically going for that effect) so you can zoom out a little more and not need to have your actors stay in your 5x5 square... Since there are raindrops, it will give the image of it raining anyway (correct me if I'm wrong... I've only ever shot rain shots.. in the rain.) 2)There's a bloody drought in a majority of the US... and it's always a good idea to conserve water wherever you are. I doubt many of those who will use this method are using reclaimed condensate water or collected it from their roof. Such a deviation from a square would allow you to use less hose too (especially since you're punching holes in it).

Check your math.... 50 sq ft does not equal a 5x5 space (5x5 = 25 != 50). Try about a 7x7. It also depends how much hose you use and how much pressure the water has.
true. yeah 7x7 is exactly 49 sq ft. close enough...considering 5x5 = 25 sq ft.
oh, and that aside, cool instructable.
