High Speed Photography

The following photographs were taken by Cooper Student Tommy Maene.
Two cameras were used.
A good camera (a Nikon) was placed in a completely darkened room with
its shutter kept open ('bulb' setting) for many seconds.
A disposable camera was used only for its flash, which was triggered by a
simple circuit using a microphone.  The flash is intensely bright and very
brief in duration, freezing the moton -- such as a water balloon being punctured
or a light bulb being smashed with a hammer.
