Easy and consistent water droplets for high-speed photography



OK, so I finally got functional PocketWizard FlexTT5 remote flash triggers, and I wanted to play around with some short-shutter photography stuff.

Obviously, the first thing to do is water droplets – everybody does it, why shouldn’t I, right?

First, I played around with an eye dropper, but the results were too inconsistent.  This past weekend, I decided to build a proper assembly for predictable water droplets – perhaps went a bit overboard, but hey…

Once I had the materials, the construction took about 20 minutes, including a few cuts on the saw.  I think I have some potential changes to make this weekend, but posting this for now.  Please let me know if you have suggestions on other things to improve this.

Materials List (may make better sense if you look at the photos):

  1. Stolen or borrowed IV bag and tube set – if you have a friend in the hospital, ask for some leftovers.  I’m sure you could do this with basic tubing from the hardware store, as well, but the IV controls are just VERY VERY VERY predictable.
  2. Three pieces of 36″ long PVC 3/4″ tubing for the frame
  3. Two 90-degree elbow connectors and two TEE connectors to fit your 3/4″ tubing
  4. A cross-shaped PVC connector to fit your 3/4″ tubing.
  5. One piece of 36″ long PVC that is small enough to fit inside your cross-shaped connector – in my case, it was also considered 3/4″ PVC, but it was a smaller outer diameter, so it couldn’t handle as much pressure.  Fits perfectly.
  6. Two rubber washers/gaskets to fit around the smaller PVC and fit into the cross-shaped connector
  7. Three tube clamps – the ones that I bought have a turn-key design that is very handy.
  8. One glass baking dish (you may have one already – I bought the Pyrex one, but I may switch to one that doesn’t have a bunch of text etched into the bottom of it.

Here’s a quick shot of the whole pile of stuff.


Three pieces of the larger PVC, one piece of the slightly smaller PVC.


Connectors a-plenty, and two rubber washers.


Clamps and a glass dish to drip into.
