The Sun Tunnels' tube arrangement creates a viewing experience most similar to which instrument?

• A. Periscope
• B. Binoculars
• C. Microscope
• D. Telescope

Answer: (D)

Viewing through a long, narrow tube focuses your gaze on a distant target by limiting light and the field of view. The Sun Tunnels use cylindrical openings that align with the sun and stars, so when you look through them you experience a framed, distant view similar to peering through a telescope—the eye piece guiding light from far away into a focused image. Other options don’t fit the idea: a periscope is about seeing around obstacles, binoculars provide a wider, magnified view with two lenses, and a microscope is for near, tiny objects. The telescope-like experience best matches how the tubes channel and frame distant celestial sights.
