Air lift
The vacuum makes the difference. When the ball moves up the tube, the airflow is directed in such a way that a vacuum is created. How must it be directed for…
Ascending magma
«Intrusion» Volcano in cross-section: This is what happens beneath its vent. What looks like magma is actually air-blown glass particles. They behave like a…
Ball on water-beam
Drawn to the jet. Table tennis balls float on a water fountain: how is that possible? The ball doesn’t stay exactly in the center of the jet. It rotates…

Floating Tap
And where does the water come from? As if by magic, the faucet floats in mid-air. Water flows continuously, without stopping. A miracle, no doubt. But can it…
Fog wind tunnel
Streamlines become clearly visible. This is how flowing air behaves: when it encounters a shape, it hugs its surface and gets deflected. The wind tunnel…
Fountain of Instability
Spitting Snake. Water sprays out in the middle of the pond. The hose moves in a snake-like motion. The end of the hose sways slowly, almost like a pendulum.…
Icy Bodies
Comet Rain Dry ice doesn’t melt when it warms up. It turns directly into a gas, and very quickly too. This gas shoots out of the small fragments involved…
Infalling Cloud
«Infalling Cloud» Resembling galactic spiral nebulae, whirling wisps endlessly plunge into the funnel. The water vapor, denser than the surrounding air, is…
Internal Waves
Wave Backwards Tilt the container – the heavier blue liquid flows downward. When it hits the container wall, it bounces back, creating a wave moving…
Jumping Water
Fascinating Water Arches. Is solid water flying through the air? Beautiful: sometimes, continuous arches form, almost like tent poles, but made of water.…
Kalliroscope©
Magic and Beauty of Flowing Motion A vortex generator or rather a spectator par excellence. It allows for enchanting, seemingly chaotic, yet somehow regular…
Large drain vortex
Plug removed: This is how the bathtub empties. A water vortex is usually seen – if at all – from above. Like the one in the bathtub drain. Here, the water…
Liquid Dynamics
Chaotic eddies, turbulent swirls – and calm zones. Turbulences become visible. In the flow tank, they appear in the water. Very similar to what happens in a…
Lying Water Disk
Water shapes sculptures. When two water jets collide, the water is deflected sideways. A water membrane forms, creating a disc. The pressure in the two pipes…
Meanderings
Meanders on glass. The glass plate is slightly tilted. Thin streams of water flow over it. What paths does the water take? The fastest path is a straight…
Musical Cloudburst
Dry Shower. What’s hitting the umbrella? It’s music! The intensity of the water jet determines the note. The umbrella acts as a loudspeaker. ❄️ Technorama…
Rift Zone
«Rift Zone» An air-filled membrane covered by a layer of sand. Press the button, and small sand fountains soon bubble up. The surface rises…
Sand images
Sliding, floating, flowing So beautiful, so fascinating: The sand, moving here between glass plates, tells a story far beyond that of an hourglass. When it…
Settling Column
«Settling Column» Sand follows gravity. The same happens in this rotating glass tube. Mostly filled with water, the sand settles at the bottom. How can the…
Slow Bubbles
«Slow Bubbles» Beautiful, how the bubbles rise slowly. In the thicker silicone oil, they have significant buoyancy but also more friction than in water. This…
Standing Water Disk
Collision of two water jets When two water jets collide, the water is deflected sideways. A thin water membrane, resembling a disk, forms. Surface tension…
Taylor-Couette Vortices
Taylor-Couette Flow Two nested cylinders: The gap between them is filled with a liquid (kalliroscope) that makes flows visible. The inner cylinder can…
The Tea Leaves Experiment / Tea Cup Experiment
«Everyday Physics» Experiment like Albert Einstein. In a paper about river meander formation, he wrote: «I begin with a small experiment that anyone can…
Tit for tat
Coriolis Effect. The water jets on this carousel are aimed toward the center. Once set in motion, they change direction. The Coriolis effect becomes visible…
Turbulent Orb
Currents and their Shapes Ever spun a globe? Turned by a hand crank, it creates horizontal bands. What happens when the movement slows down? Chaotic, stormy…
Underwater Avalanche
«Underwater Avalanche» The "sand" in this round, water-filled vessel consists of tiny glass beads. Depending on the tilt of the disc, the flow patterns vary…
Underwater Sandstorm
Underwater dunes At the seaside, in the shallow sandy shore, you can observe an underwater dune landscape sculpted by the tides. In the plexiglass sphere…
Vortex Action in Bottles
Race: Empty the Bottle A simple task: Who can empty their PET bottle faster? Turn the bottle – the rest happens on its own. But it can go even faster. How?…
Vortice Cylinder
Whirlpool in a Glass of Water Turn vigorously, please. Driven by the hand crank, the water in the cylinder starts spinning slowly, then faster and…
Water Bell
Like an elastic skin. Water flows upward against a flat surface. Diverted outward, it forms a bell shape. The shape of this bell depends on the pressure of…
Water film
Clinging Water. A daily phenomenon displayed in its most beautiful form: why doesn’t the water simply drip off the silver mushroom? Molecular interactions…
Water games
This exhibit is not accessible during the winter months. Pump like the world champions: Here, water can be pumped in the most diverse ways. A big playground…
Water Vortex
Spiral wave motion. The vortex resembles the one in a bathtub as water drains. However, the wave that forms within it is less familiar – making the image even…
Wild water wheel
Clinging Molecules. Depending on the speed of rotation, the drum carries different amounts of water up along its wall. The turbulent water wheel demonstrates…
Wind Veil
by Ned Kahn This façade is a real eye-catcher: it makes the movement of the air around us visible in an impressive way. Thousands of small aluminium plates are…
