Passive Optical Kaleidoscope Mirror Multiplier
A challenging, hands-on discovery and STEM project designed for curious young minds aged 10 to 14.
Materials Needed
- • Acrylic mirror strips (approx. 20 cm x 3 cm) (3 strips)
- • Black electrical tape (1 roll)
- • Clear plastic wrap and parchment paper (1 set)
- • Colorful translucent glass beads or broken sequins (10–12 units)
- • Black cardstock paper (1 sheet)
Pro Tips
- → Tape the three mirror strips together with reflective faces pointing inward to form a rigid triangular prism (60-60-60 degrees).
- → Build an object chamber at the far end containing colorful translucent plastic beads between clear wrap and parchment paper.
- → Rotational symmetry creates 6-fold radial starburst patterns that shift continuously as the tube turns.
Safety First
Wrap mirror strip edges with electrical tape to cover sharp corners.

Step-by-Step Instructions
Step 1
Tape three 20x3 cm mirror strips together with reflective faces facing inward to form an equilateral triangular prism.
Step 2
Seal one end of the prism with clear plastic wrap, drop in 8 colorful translucent beads, and cap with translucent wax paper to form an object cell.
Step 3
Wrap the outside of the assembly in black cardstock and tape firmly to create an opaque outer barrel.
Step 4
Hold the open eye-hole to your eye, point the bead cell toward a window or lamp, and rotate the tube to observe radial symmetry patterns.
