VDS-P Fellows Martin Kaiser and Deniz Mostarac, along with their supervisor Sofia Kantorovich, were invited to participate in the 2018 fair in November. For 4 days, they were introducing visitors to the peculiarities of ferrofluid and its applications. The unexpected huge amounts of visitors showed overwhelming interest and riddled the physicists with surprisingly deep and detailed questions, which could be answered and explained with a hands-on workshop. This way, kids could be personally brought closer to the often abstract seeming world of science and hopefully guide their fascination to a science related path.
