A Slice of Turbulence
by Ned Kahn If the crest of the wave collapsed over the surfer off Hawaii and he could bring home a slice of salami from it, he would have the original to the…
Adhesive Air
Coandă Effect: How shape, position, and surface influence airflow. The Coandă effect occurs when fluid or gas jets deviate from their original flow direction…
Aeolian Landscape
by Ned Kahn Alongside water and ice, wind is the shaping element of the natural landscape. This exhibit allows for the pleasurable "terraforming" of gently…
Air Bubbles
A pump can be used to force air into a water-filled glass tube. However, not all air bubbles rise vertically. Some do, others choose more of a zigzag or spiral…
Air Fountain
Dance with scarves. They rise and fall. Colorful scarves, moved by the airflow as if by an invisible hand. Choreography: visitors on the platform. by Daniel…
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
by Ned Kahn No, it is not real magma, but this model magma nevertheless makes it clear to us what processes are going on deep under a volcanic vent. Air is…
Ball on water-beam
What makes table tennis balls stick to the water fountain? Obviously, the ball does not ride in the middle of the jet and rotates so that it comes towards the…
Bernoulli’s Elephant
by Paul Spooner 2016, Cabaret Mechanical Theatre, England What is a pink elephant doing at Technorama? The Bernoulli Elephant is a work by the artist Paul…
Cloud Rings
by Ned Kahn Cloud maker of a special kind! If you press the lid of this huge basin filled with water mist, fog rises through the hole in the middle - up to 7…
Confused Sea
by Ned Kahn Here you can play wind god at will with a rotating and adjustable fan in a semi-circular plexiglass bowl filled with water - Aeolus would have…
Convection cells
by Ned Kahn L'air ou le liquide chaud s'élève, mais à d'autres endroits, il est forcé de redescendre. Ces formations sont appelées cellules de convection,…
Floating Tap
This exhibit is not accessible during the winter months. If this tap were not in the Technorama Park, it would probably have come from the land of milk and…
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
This exhibit is not accessible during the winter months. In the middle of the pond, water sprays out of an extremely flexible hose end. At low speed, the end…
Icy Bodies
by Shawn Lani Dry ice, solid carbon dioxide at -78° Celsius, has the remarkable property that it does not melt when heated but immediately becomes gaseous -…
Infalling Cloud
by Ned Kahn The endlessly into the funnel falling and swirling fogs resemble a galactical spiralfog. The water steam is denser than the surrounding air and is…
Internal Waves
Sure, waves are created at sea, in which the air above is not entirely uninvolved. But they also occur at the boundary between two immiscible liquids such as…
Jumping Water
If you observe the water hoppers in this exhibition object, you might ask yourself a few questions. Is solid water flying through the air here? And do all the…
Kalliroscope©
by Karl Matisse A vortex generator or rather spectator par exellence. Give the turntable a short push, then stop it or even turn it in the opposite direction -…
Large drain vortex
Usually we only look into the eye of a water vortex from above - e.g. in the bathtub outlet. Here we finally see it from the side and can regulate the flow…
Liquid Dynamics
What a wind tunnel is for air, a flow trough is for water: they make turbulence of objects visible. Different flow bodies can be positioned in the initially…
Lying Water Disk
When two jets of water collide, as here, the water is deflected sideways and usually forms a coherent water skin in the form of a disc. Surface tension is the…
Meanderings
by Michael Brown Take a slightly inclined glass plate and let a little water run over it. You would think that the water would find the fastest possible way…
Musical Cloudburst
This exhibit is not accessible during the winter months. Many people only believe it when they have taken a shower and heard it for themselves. If you stand…
Nothing but air
With a dark field illumination (schlieren optics), the smallest changes in air density (refractive index) are made visible. The apparatus is so large that the…
Rift Zone
by Ned Kahn A thin layer of sand lies over a membrane filled with air, in which there are small holes. Volcano-like sand eruptions occur above the holes and…
Sand images
The trickling sand between glass panes tells more than an hourglass. For example, it always starts to slide at the same angle, the angle of repose, which…
Settling Column
by Ned Kahn In a rotating glass tube that is mainly filled with water, the sand that it also contains always follows gravity - it settles at the bottom of the…
Slow Bubbles
Silicone oil is more viscous than water, so short jolts from the air pump allow big bubbles to form in it nice and slowly and rise solemnly. Of course they…
Standing Water Disk
Taylor-Couette Vortices
This experiment consists of two cylinders placed inside each other. The gap of 12 mm width is filled with a liquid (calliroscope), which makes flows clearly…
The Tea Leaves Experiment / Tea Cup Experiment
Coloured aluminium leaves in a cylindrical water container (approx. 10 l capacity) accumulate in the centre of the vessel after the cylinder has been briefly…
Tit for tat
This exhibit is not accessible during the winter months. When it stands still, this "water carousel" actually looks quite normal. However, when the carousel is…
Turbulent Orb
Ever set a globe in motion? If you rotate the globe with the flowing liquid by hand wheel, there are horizontal stripes because the liquid is gradually carried…
Underwater Avalanche
by Ned Kahn The "sand" in the round vessel filled with water consists of tiny glass beads. Depending on how steeply you tilt the disc, strongly different flow…
Underwater Sandstorm
If you go into the sea on the shallow sandy beach, you will see an underwater dune landscape formed by the tides. A plexiglass sphere full of water and a…
Vortex Action in Bottles
A race to (not of) two bottles! Who can empty their PET bottle faster? The fastest way to empty a bottle is not simply to turn it upside down. The exhibit…
Vortice Cylinder
The agitator inside the cylinder, driven by a hand crank, makes the water first turn slowly, then faster. The water rises up the walls and forms a whirlpool…
Warmfront
Visualisation of cloud formation on a warm front. If air masses with different temperatures meet, they are not simply mixed. Obviously, different layers form.…
Water Bell
With a flick of the wrist, you can regulate the amount of water that flows from below against the flat disc. Directed outwards through this disc, the water…
Water film
This exhibit is not accessible during the winter months. Is that really water that clings like a skin around the silver mushroom body, and even on the slanted…
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
This exhibit is not accessible during the winter months. This bowl is filled through four nozzles and has a drainage hole slightly to the side. Thus, the water…
Wild water wheel
This exhibit is not accessible during the winter months. Depending on the speed of rotation of the water drum, you can transport different amounts of water up…
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…
Inverted Bottles
Watch the rise and fall of hot and cold fluids. Investigate convection by using food coloring and water at different temperatures.
