Spotlight Experiment

Be careful: Laser light can harm your eyes and you should under no circumstances look directly into the laser beam or its reflection.

Aim
Guide the beam of a laser onto a target using two mirrors.

Materials
laser, clay, two stands, target, two mirrors, string

Conditions
Move only the mirrors! You cannot touch either the laser or the target! Alignment of the path of the laser requires only your eyesight if you think about it carefully! The provided string can be used in addition. There will be three trials. An instructor will switch on the laser and you can check your alignment. Important: only the instructor is allowed to switch the laser on, and you are not allowed to change the setup while the laser is on. The fourth attempt will be measured and counts.

Objective
Try to minimize the distance of your laser beam to the center of the target.

Time Limit
25 minutes

Ranking
The smallest distance between the center of the target and the center of the laser spot wins.
