Speaking of weapons. We have control in our country. Suppose a person wants to make a bomb. The easiest option is to buy fertilizers, oxygen cylinder, nuts, nails. In the picnic shop you need to take charcoal. Grind the coal in a mortar. Then mix: sulfur, coal, saltpeter, it is desirable to add aluminum shavings. There will be a good detonator. The fabric must be doused with resin. Pour nails and nuts onto the fabric with resin. It is advisable to nail nails with wire cutters. This will be a striking matrix. Black powder is used as a detonator. An explosion of gunpowder provokes an explosion of oxygen, and the damaging matrix scatters as a result of the explosion, causing damage.
It is clear that all things can simply be bought at the store. However, if you buy them all in one store, the police will come to you. Do you have similar control?
This little bomb can sometimes be used for hunting. But to assemble a small nuclear bomb is not a problem. Especially if there is an OZK. Given that many things are sold in the store, it is easy to make a simple rocket, and this is already dangerous. It is clear that such knowledge is not in the public domain. Moreover, it is criminally punishable to us to tell how to assemble a nuclear bomb, make a rocket and launch it. Subscription is given. Do you somehow control this?
