How to make a land mine
By The Jolly Roger
First, you need to get a pushbutton switch. Take the wires of it and connect one to a nine volt battery connector and the other to a solar igniter (used for launching model rockets). A very thin piece of stereo wire will usually do the trick if you are
desperate, but I recommend the igniter. Connect the other wire of the nine-volt battery to one end of the switch. Connect a wire from the switch to the other lead on the solar igniter.
Now connect the explosive (pipe bomb, m-80, CO2 bomb, etc.) to the igniter by attaching the fuse to the igniter (seal it with scotch tape). Now dig a hole; not too deep but enough to cover all of the materials. Think about what direction your enemy will be coming from and plant the switch, but leave the button visible (not TOO visible!). Plant the explosive about 3-5 feet away from the switch because there will be a delay in the explosion that depends on how short your wick is, and, if a homemade wick is being used, its burning speed. But if you get it right... and your enemy is close enough......... BBBBBBBOOOOOOOOOOOOOOOOOOOOOOOOMMMM!
A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both.
The name originates from the ancient practice of military mining, where tunnels were dug under enemy fortifications or troop formations. These killing tunnels ("mines") were at first collapsed to destroy targets located above, but they were later filled with explosives and detonated in order to cause even greater devastation.
Nowadays, in common parlance, "land mine" generally refers to devices specifically manufactured as anti-personnel or anti-vehicle weapons. Though many types of improvised explosive devices ("IEDs") can technically be classified as land mines, the term land mine is typically reserved for manufactured devices designed to be used by recognized military services, whereas IED is used for makeshift devices assembled by paramilitary, insurgent, or terrorist groups.
