Unlike a typical kaleidoscope, no objects are placed inside the tube. More detailed explanation: How a teleidoscope works: It works by attaching a spherical lens to a mirrored tube and projecting the outside scenery through the lens, making it appear as a pattern. Difference from a kaleidoscope: A kaleidoscope has objects like beads or glass inside the tube, and you see patterns when you look through it, whereas a teleidoscope does not have any objects inside. Features: A teleidoscope is a kaleidoscope that turns anything into a pattern, transforming the outside scenery into a kaleidoscope-like image. How to enjoy it: You can enjoy it by looking at your favorite places and objects, turning and moving it around.
