|Science Picnic with PWPW|
PWPW's stand was one of the most besieged at the 26th Science Picnic of the Polish Radio and Copernicus Science Centre. It was held at the National Stadium on Saturday, 27 May 2023.
The attractions prepared by PWPW especially for the Picnic proved extremely popular. At the PWPW stand, visitors could make a sheet of handmade paper with a special watermark, personalise a plastic card or make a number on a commemorative ID card using a pre-war manual printing machine, the so-called 'bostonka'. The greatest fun was had by the youngest visitors to the mobile printing works, but even the older ones, with a twinkle in their eye, turned for a moment into producers of watermarked paper or personalised plastic ID cards.
