Ball in a Bowl
Particle accelerator. Hula hoop meets spinning coins: balls orbit inside the sphere. Circular movements propel the two balls onto their orbits within the…
Chembongo
A stone with a mind of its own. This giant “Celtic rocking stone” (Chembongo) behaves peculiarly: when nudged, it starts to rotate. Turned the wrong way, it…
Circling Wave Umbrella
«Circling Wave Umbrella» The fabric hangs limply from the pole. When set in rotation, it ripples, much like women's skirts during a folk dance. A small hole…
Coriolis Fountain
Water with a surprising twist. If we spin around while holding the garden hose, the water jet seems to "bend." The jet follows the hose. The jet follows the…
Coupled Rotary Pendulums
Twisted oscillation. Two horizontally stacked rods with weights are connected by a steel strip. If one rod is displaced, it begins to oscillate. Soon, it…
Crushing Mill
Rolling in rotation. Three brass wheels rotate in a circle, like on a carousel. As they spin around their shared vertical axis, they are pulled toward the…
Double Gyroscope
Spin = angular momentum or torque. The angular momentum of a top moves – whether spun forward or backward – in the direction of the axis of rotation. How does…
Floating Top
Magic without tricks. With the help of a Technorama employee, a magnetic spinning top is set in motion. The spinning top can then be made to hover above a…
Gyroscope in a Suitcase
A stubborn companion. Quite heavy, this suitcase. And somehow, it seems to resist the journey. It bucks, pulls to the other side. It swerves, tips upward, as…
Infalling Cloud
«Infalling Cloud» Resembling galactic spiral nebulae, whirling wisps endlessly plunge into the funnel. The water vapor, denser than the surrounding air, is…
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…
Magic Ring
This ring never settles down… When we spin a coin, it quickly lies down on its side. This ring, however, spins much longer. Once set in motion, it refuses to…
Maxwell’s Wheel
A giant yo-yo. Pretty big and quite heavy, this flywheel. As it spins, the textile band wraps around its hub. The band shortens and pulls the wheel…
Momentum Machine
Pirouette – an elegant trick. Sometimes fast, sometimes slow, and then breathtakingly fast again – and all these variations in a fluid movement. How do…
Pendulum Wave
Chaos in perfect alignment. Eleven pendulums of different lengths. Once released, they swing in disarray. And yet, every ten seconds, they return to perfect…
RadiMax (MaxiWheel)
Infinity Top. Moment of inertia, angular momentum, and precession – a delightful interplay. Playing with the RadiMax requires some skill. On the wire-mesh…
Rockspinner
Strong Like Obelix! This "menhir" weighs five tons – yet you can move it effortlessly. The secret? The rod is perfectly mounted inside the stone, allowing it…
Rodeo Gyroscope
Rock, rock, oh wow! Take a seat, the flywheel spins. The seat lowers – affecting the axis of this gyroscope. The gyroscope reacts to this change. It tilts…
Rotating Chair with electric double Gyroscope
Disk in motion. Chair with spin. The station drives the two disks of the double gyroscope. If both rotate in the same direction, the rotating chair…
Rotating magnets
Hovering through rotation. One magnet is set into rapid rotation. If you now approach a second magnet to the rotating one, the second one starts to rotate as…
Rotating Pendulum
Standing Wave. An impulse triggered by the handwheel travels as a wave motion up the rotating wheel and back down. By periodically moving the wheel back and…
Spindrift
Rolling, spinning, wobbling, tilting. In the flat, slightly curved bowl, the discs don’t simply roll away – they always come back. How long do they spin…
Three Balls on a String
Motion patterns with momentum. Three balls on a string: what pendulum motions occur at low, medium, and high rotation speeds? Depending on the rotation…
Turntable
Rolling in place. Balls and rings on a table. On top, a rotating disc – with countless ways to play. Rings wobble, fast-rolling billiard balls stay in…
Two Wheels and a Ball
Opposing Circular Motions. In the middle: a ball. On its sides: two wheels. How does the ball move when both discs spin at the same speed? And how does it…
Water Parabola
Parabola in a natural phenomenon. As the rotational speed of this container increases, the water surface inside curves. The faster it rotates, the steeper the…
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…
Coriolis Carousel
And yet it moves! Astonishing phenomena are revealed when one earth day only lasts four seconds.
