Lately I volunteered on a series of workshops called “Will soap wash everything?” organised by Children University. Kids were about the age of eight or nine and were discovering the secrets of the effectiveness of soap for various substances. Classes took part at the Chemistry Department of the Warsaw University, so children could see how the real laboratory looks. My and other volunteers job was to help during workshops if needed and to check the lists. We also collected children’s opinions, mostly great. It is really rewarding to see the curiosity on kid’s face and how their niggling questions are answered.
