Expriments & Projects
Experience how objects are coated with metal. Aluminium is bombarded with argon ions, causing tiny particles to be released that can then deposit onto a prepared object. You are welcome to bring a small coin or similar item, which we will coat for you.
Location: outdoor area in front of the building
Time: 6:00 p.m. to 10:00 p.m.
Laser im Physiklabor
If people are talking in a room, the window panes partially absorb the sound and thus resonate. The extremely small deflections of the pane can be measured using laser beams. This method can be used not only to make sound waves visible, but also to determine mechanical material properties.

This scientific demonstration illuminates the fascinating properties of light, particularly its composition, polarization and interaction with matter. Remarkably, this can be achieved using a common household substance - sugar water. What is polarization? Why does sugar water twist light in a preferred direction? Why does this depend on the color of light?

When an otherwise fully inflated balloon suddenly collapses and goes limp, when an LED changes its color, when motion appears to slow down as if in slow motion, and when soft materials suddenly become hard and brittle – then you are encountering the world of low temperatures...

Rundgang mit verschiedenen wissenschaftlichen Stationen
We deal with the theory of kinetics of biological soft matter systems and resort to the topic of randomness for this purpose.
In addition to experiments on probability distributions, we offer interactive virtual reality experiments on random motion using the diffusion of molecules as an example.

The human body produces a large number of organic, blood-soluble substances that can be detected in exhaled air. Certain foods can also be identified in this way. We will explain how we detect these substances using modern analytical methods such as PTR mass spectrometry and what this can be used for.
Experiments every half hour from 6:30 p.m. to 10:30 p.m.
Location: between rooms 0.1.16 and 0.1.15
Together, we transfer a very thin crystal (→ “2D material”), which takes about 20 minutes. The experiment is carried out by groups of 5 to 6 people.
Location: room 1.1.46
Time: 7:00 p.m. to 9:00 p.m.

pecial metal–organic framework compounds have the ability to rapidly and efficiently bind specific substances (such as CO₂) and subsequently release them in a controlled manner (e.g. under microwave irradiation). This could make it possible to remove CO₂ from the atmosphere. With us, you can experience these processes live!

Quiz zu "Frauen in der Physik"
What do natural sciences in general and physics in particular have to do with gender? Test your knowledge in the interactive Science Quiz!
The quiz takes place continuously between 6 and 10 p.m., duration: approx. 5 minutes.

Fluorescence is the process in which a material absorbs high-energy light—such as UV light—and emits light of lower energy, often visible light. We will discover some unexpected fluorescent objects from everyday life. For example, did you know that spinach can emit red light? You can find out why with us.
Location: in front of the bridge, 1st floor, tract 3
Where do the bacteria in our everyday environment come from, and how do we make them visible? Visitors can imprint a fingertip or a clean everyday object (e.g., phone case, bracelet) on a prepared agar plate. We explain sterile working principles, why colonies form, and what can (and cannot) be concluded from colony appearance. We will show several plates prepared in advance so visitors can immediately see different colony patterns and colors.
