In order for the image to not be washed out by the blinding light, I had to set the camera to the lightning mode & night setting. The room lights were on when the shot took place. I have not confirmed yet whether room lighting makes the scene better or worse in terms of details of the sparks and explosion. The actual laser is to the far right. In the middle is a lens mounted atop the head of a nail. Just to the left of this lens is a razor blade. A shower of sparks results from a tiny hole that is drilled through the blade by the focused beam.
