Students will first decide on what type of physical phenomena they wish to investigate. Then decisions will have to be made about the type of photography (strobe, video, or high-speed flash), the kind of triggering device (sound, IR, laser, contact pressure, piezo, etc.), whether or not a time delay circuit will be necessary, and safety precautions. There are many example of student projects on the Internet and in resources available in the lab. Some popular projects are bouncing objects such as tennis balls, hitting a baseball with a bat, water drops (or other liquids), bursting of air-filled or water-filled balloons, and explosion of a popcorn kernel.
