                HOW TO MAKE A WORKING LETTER-BOMB 
                   (Uploaded by Ninja Master) 
LETTER BOMBS ARE VERY SIMPLE TO MAKE, BUT THE DIFFICULT PART IS 
MAKING SURE IT WILL DETONATE PROPERLY, OR THAT IT IS NOT OBVIOUS 
THAT IT IS A LETTER BOMB.  
 
MIXTURES: 
ABOUT 75% ALUMINUM POWDER WITH 25% IRON POWDER IS BEST.  THIS IS 
A LIGHT VERSION OF THERMITE, SINCE IT IS IN AN ENCLOSED SPACE 
(THE ENVELOPE, AS DESCRIBED BELOW A WAYS).  
 
MIX THE ABOVE WELL.  THE IDEA IS THIS: IRON CAN BURN, AT A VERY 
HIGH TEMPERATURE, BUT IT NEEDS A LITTLE HELP.  THIS IS WHAT THE 
ALUMINUM IS FOR. ALUMINUM BURNS AT A RELATIVELY LOW TEMPERATURE, 
SO IT IS USED AS A CATALYST OF SORTS. MAGNESIUM IS USED TO 
FLASH-IGNITE THE ALUMINUM, WHICH THEN BURNS THE IRON, AT A 
SUITABLE TEMPERATURE. SINCE THIS IS GOING OFF IN AN ENCLOSED 
SPACE, IT WILL BURN MUCH HOTTER AND SLOWER AND WITH MORE VIOLENCE 
THAN A NORMAL MIX. I ADVISE YOU PLAY WITH THIS FOR A WHILE, 
LEARNING YOUR MIXTURE.  
 
NOW FOR THE FUN STUFF: 
GET AN INSULATED (PADDED) ENVELOPE, THE TYPE THAT IS DOUBLE 
LAYERED.  SEPARATE THE LAYERS.  IN THE INNER LAYER GOES THE 
WONDERFUL MIXTURE, ONE YOU ARE SATISFIED WITH.  KEEP THIS SECTION 
SEPARATE, BUT IT MIGHT BE HANDLE TO TOP IT OFF WITH SOME 
MAGNESIUM, FOR A FLASH BOMB, OR POSSIBLY A MATERIAL OF YOUR OWN 
CHOICE.  
 
NOW FOR THE DIFFICULT PART: 
THE FUSE...  WE CAN MAKE A FUSE FROM ANOTHER SET OF 
CHEMICALS:	IODINE CRYSTALS, AND AMONIUM HYDROXIDE, IN LIQUID FORM. 
MIX THESE TOGETHER, IN ABOUT AN EQUAL AMOUNT, BUT YOU MIGHT WANT 
TO USE A HEAVY AMOUNT OF IODINE IF PRESSED FOR TIME.  THESE FORM 
A NEW CRYSTALLING STRUCTURE, ABOUT AN INCH LONG.	THESE ARE HIGHLY 
VOLATILE, AND I ADVISE KEEPING THEM PROTECTED.  THEY HAVE ABOUT 
THE IMPACT POWER OF AN M-100 FOR A TEASPOON.  I PUT THESE IN A 
PROTECTIVE CARD-BOARD LINING, AND PUT THEM AT THE TOP OF THE 
ENVELOPE.  RIG THIS SO IT PUTS PRESSURE ON THE CRYSTALS WHEN THE 
PACKAGE IS OPENED, BUT NOT FROM JUST SQUEEZING THE ENVELOPE. 
THIS IS TRICKY, AND I CAN'T EXPLAIN IT HERE.  SEAL THIS UP, AND 
YOU HAVE A WORKING LETTER BOMB.  
 
BY THE WAY, SINCE THE BULK OF LETTER BOMBS ARE EASILY 
RECOGNIZABLE, THEY RARELY MAKE IT PAST THE POST OFFICE.  
 
***** 
 
I FROWN UPON THE USE OF LETTER BOMBS AS A MEANS OF GETTING EVEN 
BECAUSE YOU NEVER KNOW WHO IT IS GOING TO DETONATE AROUND, OR 
THAT IT WILL EVEN BE THEM. THERE ARE SIMPLER WAYS OF GETTING 
EVEN, SO TAKE ONE OF THEM.  IT IS A FEDERAL OFFENSE TO MAKE AND 
SEND ONE.  PROCEDE AT YOUR OWN RISK.

HOW TO AVOID LETTER BOMBS: 
 
SINCE YOU MADE IT THIS FAR INTO THE FILE, I WILL TELL YOU HOW TO 
AVOID BEING DETONATED WITH A LETTER BOMB YOU MAY HAVE HAD SENT TO 
YOU.  
 
 
1) NEVER OPEN A LETTER BOMB THE WAY IT WANTS TO BE OPENED!  THIS 
   IS THE WAY OF POSSIBLY AVOIDING THE FUSE.  IF IT SET TO 
   DETONATE ON CONTACT WITH AIR, THEN THIS WILL NOT WORK.  
 
2) DON'T SQUEEZE, BEND, OR ANYTHING! 
 
3) IF IT LOOKS LIKE A BOMB, THEN DON'T EVEN TOUCH IT!  THIS IS 
   THE BEST WAY TO AVOID PROBLEMS!
