I know that Hitokiri, I know a bit about nuclear weapons.
And as for the H-bomb (Hindenburg bomb, I call it a hydrogen bomb). Apparently, as said by the Anarchists cookbook, that if you fill a 2 liter bottle with drano and add some tinfoil, a chemical reaction will take place, creating pure hydrogen. After you put the tinfoil in, you put a balloon over the bottle opening.
The balloon will fill up with Hydrogen, and then when it is full, you tie the balloon shut. Then with a long fuse explosive, you let the balloon float up into the sky (because Hydrogen is lighter than oxygen) and then BANG!!! the explosive goes off, the balloon pops and the Hydrogen explodes (because hydrogen is highly explosive when in the presence of oxygen). It's supposed to be like the Hindenburg explosion, hence the name the "Hindenburg bomb".
And messing with phone companies... reread my post again. It'll tell you.
