Science City, Kolkata, a unit of National Council of Science Museums (NCSM,) organized a science workshop to create awareness about “Gasses in our Nature” for the primary school students on February 25, 2020. The programme was organised in collaboration with the renowned NGO 'Child Rights and You' (CRY). Students were initially astonished to see the demonstration of flowers that turned into brittle with the contact of liquid nitrogen. They had fun after hearing sound of a coin near a solidified carbon dioxide that generates a sharp sound similar with scream. Almost 30 students participated in the program.
