Lets make a nuke (I'm not responsible on the use of this information) gun-type assembly method 1) Obtain uranium-238 2) Place it into an uranium enrichment centrifuge Boil it at 4131deg C (4404deg K or 7478def F), a gas is needed Pass the U-238 gas through cell membranes Capture the uranium-235 particles, let it cool into a solid The mass of captured U-235 should be 47kg (104 pounds) or above 3) Mould the U-235 into 2 pieces which will fit into a sphere 4) Attach a big metal rod to one of them 5) On the other end of the rod attach 3kg (7 pounds) of 6) Get a 3V lithium-ion battery, a switch, a barometric sensor (BME280/680 pressure sensor), 10 30mF capacitors, 20 1MO resistors and copper wires 7) calibrate the BME280/680 to 1018.33hpa and connect it to the 3V battery, in series with the switch (off)8) Create a marx generator placing 2 wires in parallel connected with a capacitor at regular intervals (use all the capacitors), in each interval connect opposite vertices with a spark gap, finally separate each inverval with resistors 9) Place the marx generator in a plastic container and fill it with ероху (Make sure spark gaps don't get covered) and debabbulate with vacuum chamber 10) Connect the marx generator with the barometric sensor, place the circuit close to the trinitrotoluene and finish the circuit with a spark gap at the surface of the explosive 11) Encase everything in a steel container, make sure the switch can be accessed from the outside 12) Turn on the switch and drop the steel box (from high altitude, the pilot should be able to get away from the explosion safely)
