Super cool: Liquid nitrogen
Heated discussions on the basics of quantum physics were followed by a cool-down in the truest sense of the word: experiments with liquid nitrogen. Dr. Noelia Fernandez, postdoc at WMI, and Julius Feigl, master's student in "Quantum Computing and Information Processing," demonstrated how various materials and gases behave at ultracold temperatures.
The girls were then allowed to immerse flowers themselves in the impressively swirling nitrogen and watched in fascination as they froze in seconds. Those who wanted to could then smash the frozen flower - rose confetti! The car hovering above the magnetic track also caused astonished exclamations and quickly drawn cell phone cameras during the demonstration of the Meissner-Ochsenfeld effect.
Highlight: The laboratory tour
It continued with a guided tour of the laboratories. And here, too, there was plenty on offer: Seeing the complex inner workings of cryostats up close, puffing helium pumps in the background. Holding tiny computer chips in the hand and discovering the qubits on them. Guessing how much the liquid helium in the giant tank costs.
