- Contact pen bomb - This is an explosive fairly simple to make and is quite effective with the proper adjustments. When this bomb is complete, you will be able to throw it up in the air and when it lands it will explode. This is similar to those little rocket shaped things you buy in the store that you place a cap in and they snap when they land (except this one packs alot more punch). It must be a push button pen. Take one of those and gut the inside. Yes, this means taking out the ink cartridge, the spring(save it), ect. Then you must unscrew the tip of the pen and place a piece of solid metal in it so that the metal is lying flat. Then you must get a thin metal rod and place it where the ink cartridge went. It must have a flat tip for the point that is placed facing the tip of the pen. You must then replace the spring of the pen onto the metal rod so that it acts the same for it. You might have to make groves in the rod so that the spring can be held in place. Now for the explosives!!!!!HAHAHAHA!!!!!!!!Fill the pen around the rod with gunpowder of your choice. Then place to caps on the metal plate and screw back on the tip. This explosive does not have a 100% detonation rate so you might have to fiddle with it a couple of times. Just to get you started, a few things that might go wrong with your pen explosive is that you have placed to many caps on the metal plate, you have not placed enough, the gun powder was getting under the rod and interfering with the caps bieng set off. Here is somewhat of a diagram: Back --------Pen casing-------\ of ---Metal rod--------------|\ Pen --------Pen casing-------/ / \ -Tip of pen | metal plate This is not a very good diagram, but it should be enough for you to get the picture. You will need to add somewhat of a wieght at the bottom of the pen right near the button. This will ensure that the pen will fall on the button to detonate the pen. How this works is when the pen hits the ground, it will press the button in with enough quickness and force that it will pop the caps. The caps will go off with a flash setting off the gunpowder and exploding the pen. Pretty simple hugh? ---+=>Vortex
