So we have to say something digressive: The result of a real bullet hitting a petrol tank is not the same as that shown in most movies. One shot can explode the petrol tank, But this is not the case, Although a pure metal projectile will rub against the air at a speed of hundreds of meters per second to generate equivalent heat, And will produce sparks after hitting the metal oil drum, But none of this is enough to ignite petrol, Especially for gasoline with a large total amount, to ignite gasoline, please remember one thing-open flame must be used. In addition, gasoline is a flammable item, but it is not an explosive item in the true sense. Only after reaching a certain total amount can explosion be caused. If the total amount is insufficient, it can only cause combustion without explosion.
