Soldiers sometimes detect the presence of tripwires by spraying the area with Silly String. It will settle to the ground in areas where there are no wires; where wires are present, the "strings" will ...
It consists of tripwire around the area, linked to one or more flares. When the tripwire is triggered, as by someone unsuspectingly disturbing it, the flare is activated and begins burning.

Sand-colored VS-50 mine intended for use in desert environments (shown beside a wristwatch, for scale). An anti-personnel mine or anti-personnel landmine (APL) is a form of mine designed for use against humans, as opposed to an anti-tank mine, which target vehicles. [1]
[1] [4] Once this has been inserted, the mine is placed in position for use and the tripwire is attached to the trip plate on the cartridge pistol. The other end of the tripwire is then secured to another surface to create a straight, horizontal tripwire to detonate the mine. [1] [4] The safety pins on both pistols are then removed. These are ...
The bomb is usually a short section of steel water pipe containing the explosive mixture and closed at both ends with steel or brass caps. A fuse is inserted into the pipe with a lead running out through a hole in the side or capped end of the pipe. The fuse can be electric, with wires leading to a timer and battery, or can be a common fuse ...
