The kaleidoscope's vibrant patterns are the result of light reflection: the three mirrored surfaces of reflect the image of the colored chips multiple times, forming a symmetrical hexagonal pattern. When shaken, the position of the chips shifts, and the reflected pattern changes accordingly, resulting in an endless variety of patterns. Steps 1. Make Fold the reflective surface into an equilateral triangle. Secure the edges of the lens with the adhesive tape included in the packaging, ensuring is stable and the corners are perpendicular. 2. DIY the Kaleidoscope Shell Use your imagination and creativity to draw your favorite colors and patterns on paper. Attach the kaleidoscope shell. 3. Attach the Pattern End (the "source" of the pattern during observation) Place colored chips in the gap between the plastic sheet and the shell (don't put too much; allowing room for movement will create a richer pattern). Seal the gap to prevent the chips from leaking out. 4. Attach the Observation End (the side you see through). Cover the gap with a piece of clear plastic and seal it securely. 5. Adjustment and Perfection Shake the kaleidoscope and observe whether the pattern seen through the small holes is clear and symmetrical. If the pattern is blurry, adjust the position of to ensure it fits snugly against the transparent sheet. Features -Material: Paper. -Dimensions: 18.8 x 4 cm / 7.5 x 1.6 inch
