# Kaleidoscope ## A kaleidoscope you turn with a finger Like the cardboard tube with beads at the end, without needing to hold it up to the light: turn it, watch the colours fall into place, turn it again. ## About this toy A round window shows a star-shaped pattern made of coloured beads: circles, triangles, diamonds and ovals in eight colours. Dragging a finger around the window turns the tube, so the picture turns too and the beads inside tumble down into a new arrangement, which the mirrors repeat six times. A tap gives the tube a shake. No two patterns are quite the same. Three-year-olds love the shake; from about five, children turn it slowly to watch single beads slide and hear tiny glassy chimes as they land. The beads stay silent until the first touch. ### How to play Put a finger on the picture and move it round in a circle, slowly or quickly. Tap once to shake the beads. The round arrow at the top refills the tube with a new mix of beads. ### A good first go Turn it very slowly and watch single beads slide from one place to another; then turn it fast and see the whole pattern change at once. ### Good to know Only one finger turns the tube at a time. The beads make a quiet chime when they knock together, at most eight times a second, so even fast turning stays gentle. With "Less motion" on, gravity is softer and shakes are smaller.

Last updated 11 October 2026 ## How a kaleidoscope works A real kaleidoscope has two long mirrors inside, set at an angle to each other, and a little chamber of loose beads or glass at the far end. Looking down the tube, you see the beads between the mirrors, plus their reflections, plus reflections of the reflections, arranged in a circle. With the mirrors at 60 degrees, the slice of beads appears six times: three times as it is and three times flipped, which is why the pattern always has six points. This toy does the same thing in pictures: it draws the slice of the bead chamber between two imaginary mirrors and repeats it, flipping every other copy. The beads are loose, and gravity pulls them down. Turn the tube and "down" moves inside it, so the beads roll and slide to a new spot. That is where all the change comes from: nothing is random except the starting mix. ## Ways to play together - **Find a colour:** name a colour and turn until a lot of it is in the middle. - **Freeze frame:** turn, stop, and describe the pattern: is it a flower, a snowflake, a star? - **Shake it up:** tap a few times in a row and watch the beads jump. - **Make your own:** look at a real object (a leaf, a toy) and imagine it repeated six times around a point. ## Setting it up The round window is as big as the screen allows, so a tablet in either orientation gives the best view. Turning works with one finger anywhere on the picture: move it round in a circle, as if stirring a pot. Younger children often find tapping easier, and each tap shakes the beads into a new pattern. If the moving colours are too busy for anyone, "Less motion" in the settings above makes the beads fall more gently. ## Good to know The chimes come from the beads knocking against each other and the wall, each colour with its own note from a five-note scale, so they always sound pleasant together. The picture only animates while beads are moving; a still kaleidoscope uses almost no battery. On a slower device the tube holds fewer beads so it stays smooth.

Not in this one: it works like a real kaleidoscope, with beads that tumble as it turns. For drawing, try the finger paint toy. ### Why does the pattern always have six points? The two mirrors are 60 degrees apart, and 360 divided by 60 is six. Every other copy is a mirror image. ### What does the round arrow do? It refills the tube with a fresh mix of beads and turns it back to the start. ### Is it noisy? The chimes are quiet and limited to eight a second. The round speaker button at the top turns them off. ### Can I use a keyboard? Yes. Focus the picture with Tab, turn it with the left and right arrow keys, and shake it with Space or Enter. ### Is anything saved? No. Each visit starts with a new mix of beads, and nothing is kept or sent.
