A nuclear fission reaction.
To use natural uranium in a bomb either of 2 things must be done first, both are expensive and require large infrastructure investment to do them:Enrich the uranium from 0.72% uranium-235 (natural) to 93.5% uranium-235 (Oralloy or HEU).Process the uranium to turn some of the uranium-238 to plutonium-239 in a reactor then chemicallly separate the plutonium from the rest of the irradiated material chemically.In WW2 the US did step 1 at Oak Ridge, TN using a gigantic gaseous diffusion enrichment plant and an electromagnetic separation plant; and step 2 at Hanford, WA using several graphite moderated reactors and large chemical separation plants called "canyons".
Enrichment of uranium-235 is done.
The US detonates a uranium bomb over the Japanese city of Hiroshima, killing more than 140,000 people within months. Many more later die from radiation-related illnesses. The US explodes a plutonium bomb over Nagasaki. An estimated 74,000 people die by the end of 1945. Little can be done to ease the suffering of the victims who survive the blast.

all you have to do is get a bomb and make it in your house, done!!

Locate Uranium ore depositsMine UraniumBuild Uranium enrichment plantEnrich Uranium to about 90% pure Uranium-235Design bombBuild bombThe first 4 steps will take an industrialized country about 4 years to complete. Step 5 can be done in parallel with those steps. Step 6 is more or less trivial after the others are complete.A Plutonium based bomb requires a few additional steps but takes roughly as much effort and time.
