Here is an interesting experiment that it a little bit about high speed photography, and a little bit magic science.
FPSoutback share a little high speed photography as he uses a sugar cube instead of a strobe to capture a speeding bullet.
As with most high speed photography, the actual exposure is a bit long – a two seconds exposure using a Sony NEX 5N. Usually in this kinds of shots, a sensor detects the bullet and triggers a strobe.
In this particular setup, the energy created from splitting the sugar cube creates the flash of light in a process called triboluminescent.
But this is not all, the fun really begins when you start adding interesting liquids to the sugar cube shifting most of the light from the UV part of the spectrum into invisible light.
