laser pointers
Focused light devices
Laser pointers are handheld devices that emit a narrow, focused beam of light, used to highlight points on screens during presentations or to direct attention at a distance.
Cat owners use them to exercise pets by moving the dot across floors and walls.
Higher-powered versions can damage eyesight or cause problems for aircraft pilots: A teenager was arrested for shining a laser pointer at a helicopter.
