On 7 October 2017, at Park im. Poległych Bohaterów in Zabrze, the CMPW PAN participated in a family picnic organised as part of the "Skarbnikowe Gody" event by the Municipal Culture Centre and the Municipal Office. The picnic was associated with the celebration of the 95th anniversary of granting urban charter to Zabrze. It is an event with a rich, long-established tradition, addressed both to the residents of Zabrze and to the residents of nearby towns. During the picnic, artistic workshops, educational programmes for fun, games of skill and demonstrations of chemical experiments took place. The employees of the CMPW PAN presented a series of interesting experiments to the guests and encouraged those willing to perform them together. The CMPW PAN stand attracted great interest, with the biggest impression made by obtaining colourful gel plastic masses.
