Last saturday the Dioscuri Centre together with a few other groups from IChF participated in the Science Fair in Warsaw. This is one of the largest events of this kind in Central Europe; the fair attracts huge crowds (tens of thousands) and lasts from 11am until 8pm. Our group prepared two demonstrations: live imaging of the process of killing bacteria (E. coli) with ethanol in a microfluidic channel, and a set of Petri dishes with different letters and symbols painted with fluorescent paints. The first was to demonstrate what happens when you use ethanol for disenfection – as you can imagine, we had a few interesting comments on this from the public. The latter experiment demonstrated the principles of fluorescence, thought it turned out to be also a magnet for children who just wanted to see what we hid in a “black box” (a safe blue-light illuminator to make the plates glow).
Many thanks to Asia, Klaudia, Ilyas, Pragyesh, Jarek who helped organize this event and tirelessly presented the experiments to the public!
