- When you pull the trigger on the "gun", notice that the screen briefly
- goes completely black except for a white spot. Then in the gun there
- is a lense and a photodetector. The photodetector gets the white spot
- (assuming you aimed correctly) and then the screen goes back to the normal.
- Then the duck, or whatever, falls out of the sky.
