Twisted Paracord Perimeter Alarm

Paracord can be wound and twisted to make very effective trigger systems for both traps and perimeter alarms. This hack will demonstrate how it can be attached to a tripwire to alarm you when someone is approaching your camp. Start by tying 2 pieces of paracord between 2 small trees. The ideal distance between trees is less than 2 . Insert a stick between the 2 pieces of paracord and twist until the line develops enough pressure to spin when you let it go. Place your tripwire across the trail and attach the end of the line to the lower portion of this trigger stick with a loop while it is wound very tightly. The taut tripwire and loop will hold the trigger stick in place. Finally, hang a cluster of empty cans so they dangle in the path of the spinning trigger stick. When the line is disturbed the loop will be pulled from the bottom and release the spinning trigger stick into the cluster of cans, sounding the alarm.
