The salt on the fries...
At the first Children's University lecture of the year, Prof. Elisabeth Clausen from the AMT explained how the salt gets on the chips.
Last Friday, 16.09.22, about 400 inquisitive children sat in the lecture hall building CARL and wanted to know how the salt gets to the fries. Some children participated in the Children's University for the second time and showed great enthusiasm for the lecture series.
First, Ms. Elisabeth Clausen practiced the miner's greeting "Glück auf" with the children, which some of the young listeners already knew and happily shouted into the hall. Afterwards, the professor explained all the steps of rock salt extraction during her lecture: from its formation "even before the age of dinosaurs" to the evaporation of the salt layers and the different types of extraction. A virtual mine tour including blasting made the topic even more vivid for the children, who eagerly took notes and asked many questions.
Finally, Prof. Clausen explained how salt is extracted from seawater. Her colleague Maximilian Getz demonstrated in an experiment how easily salt can be extracted from seawater, which many of the participants wanted to try out for themselves on their next vacation.
After the lecture, the children were able to take "real salt chunks" home with them, but the bigger surprise was waiting outside the lecture hall: the Studierendenwerk distributed free French fries.
All in all, it can be said that this Children's University was a complete success. We thank you for the lively participation!
