Beijing, April 3 (Youth.cn) - On April 2, 2025, in Lianyungang, Jiangsu Province, a science educator captivated young students by demonstrating the "flame palm" experiment - a safe combustion demonstration using controlled ignition of gas (e.g., butane) mixed with soap on the palm. The activity allowed children to interactively explore scientific principles while learning about fire safety and chemical reactions. Photo/CFP
