Balloon explosions, gorgeous fireworks, rocket launches, incendiary bombs, armor-piercing bullets... sounds a bit "dangerous" and professional explosion, and there are many applications in life. On May 20th, at the public opening day of Beijing Institute of Technology, Professor Feng Shunshan from the State Key Laboratory of Explosion Science and Technology of Beijing Institute of Technology brought a vivid science lecture. As an important part of the National Science and Technology Week, Beijing Institute of Technology held a public open day on the 20th with the theme of “Into the Explosion Science, Impacting the Future of Science and Technologyâ€. The State Key Laboratory of Explosion Science and Technology opened to the public free of charge. Beijing 55th Middle School, 11th School, Science and Technology Attached to more than 100 teachers and students representatives, parents of students and social enthusiasts have been in close contact with the explosion, which is a dangerous professional field.
From black powder to metal hydrogen and total nitrogen compounds, Feng Shunshan told the audience about the development of explosive technology. At the same time, it introduces the common explosive research techniques, including laser interferometry, pulse X-ray photography and explosion virtual test technology. Finally, the application of explosion technology such as air shock wave, rock explosion, explosion-driven flyer, and explosive energy gathering effect is introduced. Feng Shunshan said that the explosion science is widely used in national life. In addition to the well-known military applications, it also has great effects in emergency rescue and navigation clearing.
Public day event
In addition to popular science lectures, the event also demonstrated to the public the achievements of military and civilian integration in the field of explosion and protection, including explosive synthetic diamond , explosive spraying, explosive welding, explosive sintering, rotary detonation engine, flexible explosion-proof technology, 3D printing protective materials, Metal water, etc., is an eye-opener. 
Public participation in the explosion test
What excites the audience is that they are fortunate enough to personally participate in the explosion experiment. The teachers of the key laboratory gave a practical demonstration of the density test of energetic materials, the flash point test of explosive materials, the hardness and roughness test of protective materials, the ignition energy of dust explosion and the minimum ignition temperature test of dust, and the experiment of light air gun shooting. The thrilling and stimulating test has greatly deepened everyone's scientific understanding of explosion safety. The public on the spot said in unison: "I didn't expect you to be such an explosive school. It is very knowledgeable." As the only national key laboratory in the field of explosion in China, the State Key Laboratory of Explosion Science and Technology has become an important scientific research, personnel training and academic exchange base in the field of explosive science and technology.
