In the summer of Nobel 1862, he began to study nitroglycerin. This is a difficult journey full of danger and sacrifice. Death has always been with him. An explosion experiment exploded and the laboratory was blown up without a trace. All five assistants were killed, even his youngest brother. This amazing explosion gave Nobel's father a very heavy blow and died soon. His neighbors, out of fear, also sued Nobel to the government. Since then, the government has not allowed Nobel to conduct experiments in this city.

But Nobel is indomitable. He moved his laboratory to a boat in a suburban lake to continue his experiment. After long-term research, he finally found a substance that is very easy to cause explosion-mercury fulminate. He used mercury fulminate to make explosive detonator, which successfully solved the problem of explosive detonation. This is the invention of detonator. This is a major breakthrough on Nobel's scientific road.

Mine development, river excavation, railway construction and tunnel excavation all need a large number of high explosives, so the advent of nitroglycerin explosives has been widely welcomed. Nobel built the world's first nitroglycerin factory in Sweden, and then set up a joint venture abroad to produce explosives. However, the explosive itself has many imperfections. It will decompose when stored for a long time, and strong vibration will also cause explosion. Many accidents occurred during transportation and storage. In view of these circumstances, the governments of Sweden and other countries have repeatedly issued bans to prohibit anyone from transporting explosives invented by Nobel, and clearly put forward that Nobel should be investigated for legal responsibility. In the face of these tests, Nobel was not intimidated. On the basis of repeated research, he invented a safe explosive with diatomite as absorbent. This kind of safe explosive, called yellow explosive, shows great safety under the action of fire and hammer. This completely dispelled people's doubts about Nobel explosives, Nobel regained its credibility, and the explosive industry also developed rapidly.

On the basis of the successful development of safe explosives, Nobel began to improve old explosives and research and produce new explosives. Two years later, a new colloidal explosive made of gunpowder cotton and nitroglycerin was successfully developed. This new explosive is not only powerful, but also safer. It can be rolled between hot rollers or pressed into rope shape under hot air. The invention of colloidal explosives has been widely concerned by the scientific and technological circles. In the face of his achievements, Nobel did not stop. When he learned the advantages of smokeless powder, he devoted himself to the research and development of mixed smokeless powder and developed a new type of smokeless powder in a short time.

Nobel made many inventions in his life and obtained 255 patents, including 129 kinds of explosives. As he lay dying, he was still obsessed with the research of new explosives.
