Lessons activity is in
  • dark room
  • pocket lasers
  • small mirrors
  • optional: cornstarch for visualizing laser beam

Give students pocket lasers, small mirrors, and tape.

Ask them to reflect the laser around the room.

It is more challenging than expected, as a slight change of angle of the mirror will change the direction of the laser dramatically.

Very fun, but very dusty for other objects in the room: clap cornstarch in the air to visualize the laser beams. Students can design a challenge where they have to crawl under and climb over laser beams without touching them.
