3 or 4 safety mirrors- ours are 7x7cm
brown parcel tape
greaseproof (waxed) paper
Tape the mirrors together-shiny side inwards
Cover one free surface with card and tape this down securely. Make a hole in the card using a pencil or scissors.
Hold the greaseproof paper side to the light or shine a torch through this end. Look at the sequins through the viewer.
Shake and look again.
I guess that the best design would use a flexible mirror in a tube.
Have you ever made a kaleidoscope? Any thoughts about the design?
