The Periscope Experiment Kit introduces children to the foundational science of optics, specifically how light reflects off mirrors to allow viewers to see objects outside their direct line of sight. By positioning mirrors at precise 45‑degree angles, the periscope redirects incoming light down the tube and toward the viewer’s eye, demonstrating how reflection can change the path of light.

Through constructing, folding, and experimenting with the periscope, children gain hands on experience with light behaviour, mirror orientation, and visual perception. These simple but powerful demonstrations help them understand real‑world applications from submarines to observation tools making the abstract concepts of optics tangible and fun.
