Is Harry Potter invisibility cloak possible to produce in real life? How are the waves created? Is it possible to “build” a sun? If you want to learn how to answer these questions (and many more) join this course! This course can be an opportunity for small kids (<= 12 yr. old) to stimulate their curiosity as well as to answer their many whys. For teenagers, this can serve as a complement to the high school classes and offer a fresh perspective on what the future would be. I graduated in Physics at ETH Zurich in 2021 and I did my bachelor in Italy. Previously I was a tutor for high school kids in physics and mathematics.
