I'm a big fan of guns. I love shooting them and i love the eminence power they posses. Guns are really amazing machines, for being so little and simple they pack a punch. Mechanical reactions are what make guns guns. When shooting a handgun, once the trigger is pulled, the hammer falls down with tremendous speed and strikes the primer. The strike causes a spark which then ignites the gunpowder. The explosion form the gunpowder propels the bullet out of the gun at high speeds. It is quite incredible how something so little and compact can do something like this.
