Turn any room into a high‑tech spy zone with the 4M KidzLabs Spider Spy Motion Detector — an exciting STEM gadget that lets kids build their own working motion‑detection alarm system.
Using a real LED light beam transmitter and receiver, children create an invisible security barrier that sounds an alarm whenever someone crosses it.
Perfect for budding secret agents, this kit encourages problem‑solving, critical thinking, and hands‑on learning.
Kids can even design reflective light mazes using mirrors to challenge friends, protect secret treasures, or set up spy missions around the house.
