One interesting thing I learned on vacation was the effect camera flash has on shooting arcade. By shooting arcade I mean those amusement park attractions where you shoot at targets to make things move. Piano player hits a few notes, skulls snap backward, bottles do somersault, and so on. I had my share of losing a dollar or so and could not make anything move. Later on, my big group descended upon the shooting gallery so I thought I should take a few pictures of the group members with their rifles. As the flash briefly brightened the gallery, many of the nearby objects went nut! I never knew what normally makes the objects move as there was no actual bullets flying out of the rifle muzzle, but a simple digital camera flash sure did the job.
It was closing time and there was no amusement park attendants nearby to tell me to quit it so I flashed the scene a few more times, much to the amusement of the group. Too bad there was no prize involved otherwise I could have won one of those large stuffed animals.
