STEM DIY - Telescopic Periscope

Experimental principle: The paper periscope uses two mirrors to reflect light twice before it reaches the eye, allowing you to see the underwater world.

Extended dimensions: 26 * 4 * 4CM

Assembly steps

[1: Folding the periscope] Fold the paper periscope along the edges of the paper, and secure the connections with double-sided tape.

[2: Inserting the lenses] Peel off the film from both sides of the lenses, and secure them to the top and bottom of the paper periscope respectively, inserting the longer end into the shorter end.

[3: Experiment] After completing the assembly, invite your friends to experiment together. Observe what changes in the world viewed through the periscope.
