Most illusions at Twist happen in front of you. This one happens all around you.
Step into the Kaleidoscope Tunnel, and you’re not looking at a kaleidoscope; you’re standing inside one. Mirrors on every side multiply you into a ring of copies stretching off in all directions, while colour and pattern pour across the walls, shifting and rippling as you move. Look up, look down, turn on the spot. There’s no flat surface for your eyes to land on and no clear edge to the room. It’s you, repeated, wrapped in moving light.
What is the Kaleidoscope Tunnel?
The Kaleidoscope Tunnel is a walk-in mirror room in the heart of London that turns one person into an entire pattern.
Angled mirrors line the space, so wherever you look, you see yourself reflected, then those reflections reflected again, fanning out into a symmetrical burst that seems to go on forever. On top of that, moving projections wash across the mirrors in colour, from electric blues and pinks to fiery reds and greens, changing constantly so the pattern never sits still.
Every move you make ripples outward across dozens of reflections at once. Stretch out an arm and a dozen arms reach with you. It reacts to everything, so no two moments in the tunnel ever look the same.
The science behind the Kaleidoscope Tunnel
A kaleidoscope works by placing mirrors at angles to one another. Light bounces off one mirror onto the next, and each reflection becomes a new object for the mirror opposite to reflect again. That chain of reflections is what turns a single object into a full, symmetrical pattern.
The Kaleidoscope Tunnel scales that idea up to the size of a room and puts you inside it. You are the object being reflected. The angled mirrors take your shape and repeat it around the space, over and over, into a pattern that appears endless. The reflections don’t truly go on forever, because each bounce loses a tiny bit of light and eventually fades, but there are more than enough to lose count.
Then comes the twist. Projected light plays across the mirrors and gets caught in the same web of reflections, so the colour and pattern multiply exactly the way your body does. Mirrors handle the shape. Projection handles the colour and movement. Together they build a world that shifts every second. Want more of the how? Our Science of Illusions page goes deeper.
What to expect
The Kaleidoscope Tunnel is a walk-through space, so take your time in it rather than passing straight through. Move slowly, and the whole pattern flows with you. Move fast, and it scatters. Reach out, spin, look up at the ceiling and down at the floor, because the effect surrounds you completely.
It’s one of the more immersive, sensory moments at Twist, and one people tend to linger in. It’s part of your wider visit to the museum, alongside 80+ interactive illusions, so there’s plenty more once you step back out.
Worth knowing before you go in: the tunnel uses bright, moving projected light. If you’re sensitive to that, read the accessibility note in the FAQs below.
Photo and video tips
This is one of the most photogenic spots in the whole museum, and video captures it even better than a still.
- Film a slow pan or spin. Turning slowly on the spot sends the whole pattern rotating around you, which looks incredible on video.
- Shoot upward. Pointing the camera up the mirrors exaggerates the endless, radiating effect.
- Wear a bold colour. A bright top stands out against the shifting projections, making your reflections pop.
- Strike a wide pose. Arms and legs out means more of you to multiply, so star shapes and big stretches read brilliantly.
- Wait for the colour to change. The projections cycle through blues, pinks, reds, and greens, so hold on a moment while the palette you want loads.
