The Centre celebrated the National Science Day on 1st March 2021. Students at the 9th and 10th standard level and their science teache rs from the Government high school, Hullegoudana Halli, Bangalore North wer e invited to actively participate in the event. The programme began with a video introduction to the research activities of CeNS. Prof. G.U.Kulkarni, the Director of the Centre was the Chief Guest. In his address Prof. Kulkar ni stressed on the importance of the Day, how students should make best use of their free time and develop scientific curiosity. As an example, he quo ted the case of unique face mask designed and fabricated during the lockdow n period by a few researchers of the Centre, and now commercialized. After a short video clip on the life and works of Prof. C.V. Raman, a number of s hort, but interesting science demonstrations were conducted catering to the academic level of the visiting students. The demonstrations conducted by t he research students of the Centre included a simple apparatus to realize R aman effect, visualization of simple optical effects using laser beams, gen erating irregularly shaped soap bubbles, a lay-man’s chemical method to pre vent corruption, magnetic levitation, Leidenfrost effect, emission of colou rs from nanocrystals, non-standard rheological materials, wonders from penc il writing, de-fogging and electrically switchable smart windows. The demon stration was followed by a breif explanation of the involved phenomena and where it gets applied. The whole challenge was to do the explanation in Kan nada language, the medium of instruction of the visiting students. The CeNS research students and coordinators stood upto the challenge quite well. Th e event that lasted a little over 2 hours, was seen to be thoroughly enjoye d and appreciated by the visiting students and teachers, an indication of w hich also seen in the post-event feedback
