In 2002, a renegade science photographer, Martin Waugh, was playing with high-speed photography and discovered he could image two drips of water hitting each other. This special event takes place under special conditions; when a single drop hits a water surface and rebounds up in perfect timing for a second falling drip to collide with the first at its peak of rebound. Martin decided he had to build a special computer controlled dripper to make these collisions and explore the topic photographically. Martin’s drips went viral on the Internet and became the inspiration for numerous arts today. Several companies like Mumford Time systems and Cognisys Inc. make special systems just for this double drip photography. In this article I will explain how you can make your own. For this project I made a stand for the dripper that was more complicated than needed since I plan on using it for a number of demonstrations with students and need it easily adjusted. I like using 11 layer plywood; sold for cabinets and fine woodworking. This material is 5/8 inches thick. This wood is quite stable, free of voids, and is a lot easier to work with than machining metal. Over the years, this plywood ...
