How do you make an atomic bomb?

Obtain a sample of plutonium or uranium. Enrich it to weapons-grade. Construct a casing. Build your ignition method within the casing (implosion or gun-types are most common). Insert the fissile material. Voila!
Or if you didn't understand that, you need two separate masses of uranium which when added together are more than the critical mass. Then you need a regular explosive to drive the masses together, and keep them together long enough for the fission to occur. A lot of heat and energy is released because although the atoms lose just a tiny amount of mass, the energy equivalent is enormous (the bang in other words).
