TIMING IS EVERYTHING
The hardest thing? Timing. There are two ways to ensure that your camera catches the exact moment that the drop rebounds off the receiving liquid. The cheapest is simple trial and error. Using a digital SLR, I see immediately on the LCD if I've popped the flash too soon or too late. After a dozen trial shots, my reflexes sharpen, and I start to get keepers.
The other way is with a motion- or sound-activated device that automatically triggers the flash units when an infrared beam is broken by the falling water drop or a sound is emitted by the drop hitting the H20. I use kits sold by HiViz (www.hiviz.com). If you have even a small knack for electronics, you'll find these kits affordable and fun to use.

TIPS FOR DRIPS
The depth of the receiving liquid determines the shape of the splash or drop. For crown shapes, fill the receptacle with liquid to 1 centimeter or less. For column shapes, add more liquid. Plain water works best. Of all the liquids I've tested, it's the most reflective, with the perfect viscosity for fantastic shapes.
