Title: Second file in the SIMPLE explosives series. R.J. Date: 2/7/88 Time: 11:50 am This is the second file in the R. J. MacReady pyrotechnic series. If you don't have the first file, it is advisable that you download that one as well as subsequent ones. Motor Mine: This device causes basically the same damage as "the basic mine", but is more conveniant if the person happens to miss stepping on it. Materials: Film Cannister (or as I said before, any size container). Match books. 17 packs fills a Black's film cannister. Wire (preferably long lengths). Small electric motor (available at the Science Centre) First, take the lid of your container, make a small hole (not a square hole like in the mine). This should be big enough to hold the axle of the electric motor snuggly. You need to make a small cardboard disk, or, if you can find one, a small plastic gear like piece meant to fit on an electric motor, but I doubt you will. You must cover this small disk (about a centimetre wide) with the brimstone from the matchbooks. Fill the container with matcheads, push the motors axle through the lid, push the disk on the axle from the other side, put on the lid, tape the whole thing up, plus the motor, so it doesn't wobble about. Hook your wire up to the terminals on the motor, then to a switch or a battery or whatever. Conceal the mother, and stand back, you will hear a high pitched screach (carrier detect?) of the motor grinding, then BOOM. Works well. String Cannon: Once again, the basic principle of the mine is used here. Materials: Container. Matchbooks. Piece of piping with one end closed off (make sure it is possible to put a hole in the closed end though). ABS piping (available at Home Hardware is good because the film cannisters fit PERFECTLY. But only the see through ones. Ask Blacks for TRANSPARENT film cannisters. String. Violent nature. Ok, make a basic mine (you MUST have the first file to do this). But don't put in the match heads yet. Pierce a hole in the bottom of the cannister (big enough for strong string to fit through). Now, once you have made the 2 or 3 match button (from the first mine explained) you will be pulling it from the bottom rather than stepping on the top. Tie the string to the matches in the brimstone box and then bring the string through the bottom of the cannister, fill the cannister with match heads, and put on the lid. Once again, the more you tape, THE BETTER. You want to hold this explosion as much as possible, so when it goes off it's more powerful. Put a hole (for the string) in the blocked end of the piping. You might find it hard to the string through, but try and get it through a small a hole as possible. You don't want anything coming out the back! A good idea is to, insert the string through the pipe, THEN do the rest explained above (as you can see, I suck at writing .DOC files). And drop the mine CAREFULLY down to the bottom of the pipe. Now walk around like you have a shotgun and whenever you want to blow something away, just point and pull the string. A spray of match heads, fire, plastic bits etc. will fly out, pretty impressive I guess. Look for other files in this continuing series on SIMPLE devices. Written by R. J. MacReady.
