    A laser bounced off two mirrors and onto a light sensor. While the beam lands, nothing happens. Break it by walking through, and the buzzer goes. It is the kit that gets the most attention on a display table, and the mirror alignment is a real problem for the learner to solve.

    What is in the pack

    • Laser source
    • Two mirrors
    • Light dependent resistor
    • Buzzer
    • 4 x AA battery case and an assembly diagram guide

    Covers Electrical Systems and Control in CAPS Technology, Grades 8 and 9. The obvious pick for a museum, vault or security brief.

    Note: this is a component pack. The model, backing board, batteries, tools and glue are not included. Do not look into the laser.
