The 3rd Science Picnic in Radom was held on the 2^nd of June this year. The event was organized by the City Council. The Institute was, for the first time, given the opportunity to present its original test apparatus and devices and make Radom inhabitants familiar with the work of its laboratories. Those who visited the Institute’s stall displayed on the main street of Żeromski could see what the researchers’ job look like and even do the experiments themselves, of course under the supervision of experienced scientific staff of the Institute.
