"Delta Phi"

Optical phenomenon: caustics. The surface of this object resembles that of moving water. Illuminated from above, it reflects incoming light rays in various…

A Table with loose Legs

Three, two, one – stable. How many supports do we need to stabilize a tabletop? Without screws, without glue, of course. Sharp-minded (and experimental)…

Air cushion

Inventive talent is called for here! Use scissors and tape to build objects out of paper that float on the wide air cushion. While testing and optimising, you…

Aurora

A different kind of reflection. Colored filters in a mirror: why don’t we simply see their exact image? The surface of the mirror is rough. Restless,…

Banana

If you place a blue filter exactly on the yellow banana, the banana appears green - logical, isn't it? A larger blue filter that also covers the white…

Beam Bridge

The simplest form, but not the most stable. This bridge demonstrates the forces acting on a straight beam when it is loaded and supported only at its two…

Break the code

Qxpoa gvp pbuu: Cryptography. An encrypted text appears on the monitor. The challenge is to decrypt it with as few errors as possible. But there are over four…

Bridge the Gap

Building bridges is not so easy - especially when you are not allowed to use nails, screws or glue! Here you only have nine identical wooden blocks at your…

Cartesian Diver

Sinks / Doesn’t Sink Sometimes called a “Cartesian diver,” this hollow body is partially filled with water and air. Depending on the pressure in the liquid,…

Chaotic Pendulum

Momentum and Joint A long, light pendulum connected to a small but heavy pendulum. A push on the knob sets the entire system in motion. The effect on the…

Chaotic Pendulum II

Momentum and Reversal Three smaller pendulums attached to a large rotating arm. A push on the knob sets the entire system in motion. The effect on the three…

Circular Deformations

Geometric shapes come to life. What we think we see in the shapes of spinning discs! Ovals wrapping around stationary circles. Cones wobbling in a…

Circular Deformations

Patterns come to life. Ovals form around stationary circles. Funnels emerge, cones rise. Curved lines perform a serpentine dance. Images that, when observed…

Color Contrast

How blue blue can be. Two color squares, one lighter, one darker. Are we sure? As different as we perceive them, they actually share the same color. We…

Dancing iron particles

«Dancing Trees» 81 electromagnets are covered with fine iron dust. The electromagnets can be controlled either via a sensor surface or via prepared programmes…

Deep Walls

Shadows in motion - moving silhouettes. On a large projection surface, divided into 16 fields, shadow images move towards and away from each other. Each…

Delayed Viewing

Acting and seeing with a time delay. Catching fish with a fishing line: normally, it’s simple enough, as the magnet on the line is easy to guide. But it gets…

Distorted Room (Ames Room)

Little one grows tall. An absolutely ordinary room, at least when viewed through the peephole. But wait, the little brother grows taller than the big sister…

Electric circuit

What conducts electricity and what does not? What is an electrical circuit? With small, individual electrical components, you can build simple circuits…

Electromagnetic puppet theatre

Electricity moves magnets. Three stations each contain four coils whose frequency and phase shift can be adjusted. Figures with magnetic legs can be placed on…

Encoding Text - Caesar’s disc

« Caesar’s Wheel » Encoding and decoding with two rows of letters that can be shifted relative to each other. Even in Caesar’s time, information was protected…
