Tracking atoms – composition of matter

Physics lessons in mainstream school education were extremely limited during the 20th century – especially when it came to expensive and complex experiments.…

Chance Happenings

Capturing randomness – with dice. Four faces of these dice are white. The other two faces show a red circle. After each roll, the dice with the red circle…

Cloud Chamber

Particle Zoo: Ever seen a muon? Electrically charged particles are not directly visible, even in the diffusion cloud chamber. However, alpha and beta…

Double Refraction in Calcite Crystals

Viewed through Iceland spar: The lettering appears doubled. Light entering this Iceland spar calcite crystal is split into two beams with opposite…

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…

Magnetic balance

Floating through diamagnetism. Underneath a large ring magnet is a transparent box with a small magnetic cube and a base made of graphite. At exactly the…

Neon Sinfonie

Pattern effect in plasma. A shimmering glass chalice – filled with fans of light. The "Plasma Chalice" demonstrates, in this chalice with an extremely long…

Seeing atoms

Ion Trap: One of a kind worldwide! Invisible particles, which we otherwise know only from textbook illustrations, become visible here. In an ion trap,…

Spectra

Elements and their colors. Distinguishing individual hues from a color impression: it’s as challenging as identifying individual instruments in an orchestra.…

Superconductivity

Hovering in the cold. Together with a Technorama employee, various experiments with superconductors can be carried out here.

The big is in the small: crystals

Amazing Order Shake it, please. When the balls come to rest, they arrange themselves into regular patterns. These patterns can be compacted, almost to…

Triad - metal, stone, wood

This is music! Comparing the sounds of different materials: this is how stone, metal, and wood resonate. The material, its length, volume, and the strength…

Watch Water Freeze / Ice Flowers

Watch Water Freeze Crystals form on the cold surface, like frost flowers on windows, a sight we see less often thanks to better insulation. Here, you can see…

White Plasma Plume

Art with the fourth state of matter. Beautiful, this work by Wayne Strattman. Elegant, the glowing white plumes in “White Plasma Plumes” as they move.…
