On October 7, 2022, the Centre for Polymer and Carbon Materials Polish Academy of Sciences participated in the "XVIII Science Day". This year's edition of the Science Day was organized in a revitalized space around the water tower built in 1909 at ul. Jana Zamoyskiego 2. The patron of this year's edition was the Silesian Park of Medical Technology - Kardio-Med Silesia and the Professor Zbigniew Religa Foundation of Cardiac Surgery Development. The purpose of the Science Day was to promote scientific and technical achievements among the city's residents, especially among schoolchildren, and to stimulate interests in an interactive, accessible and unconventional way, to encourage closer learning about areas that may seem difficult, unknown, sometimes - seemingly not very interesting. The employees of the Centre presented interesting and effective chemical and physical experiments.
