wish I was loving kidding. Do you know why is random.org named random.org? Do you know how many people I have to roll for before you? Only once have I mary-sued a roll, and it's Menen's. Try again. ...On second thought don't, you'll get nowhere.
you use plutonium 246, lead insulation, six pieces of lead coated tubing, water, and a lead suit for extra protection. the plutonium 246 is not as long lasting as plutonium 244 of 236, as its half life is 33 million years; also emits beta particles.
the plutonium core which is inside the lead insulation (7 centimetres of lead; tubing is 2.5 centimetres of lead) is now beeing directed toward the brick wall, due to the beta particles being extremely dangerous, and being distirbuted in rapid amounts, more than a usual plutonium atom, the plutonium breaks down three bricks in the wall, along a vertical path. due to the laws of physics, the wall should lose structural integrity and fall. hopefully.
You forgot to stuff lots and lots of iodine-131 to further increase the bomb's power.
I reject your reality and substitute my own
