A tripwire is a mechanical deviceIt is usually used in weaponry.In war, they are used to cause an enemy to fall.They are also able to be used for less sinister purposes.You can use a tripwire as an alarm for a campground or a simple prank.
Step 1: Get your materials.
You will need fishing line, a mouse trap, ring caps, tent pegs, nails, screws, and rubber bands.
Step 2: There is a tent peg and a mousetrap.
The tent peg has a mousetrap on it.To screw them together, use a screwdriver and wood screws.
Step 3: Behind the bait pedal, screw through the trap.
The bait pedal is the part of the mouse that moves to release the trap.There is a hole through the mouse trap.You will tie a knot over the bait pedal.
Step 4: The pop caps have to be cut out.
Cut out individual pop caps if they are in a ring.A small nail head is what one should fit over.You can use a glow stick instead of a pop cap.
Step 5: Release the trap multiple times.
When it releases, you need to see where it hits the wood.
Step 6: Hammer with two nails.
Where the bow hits the wood, drill a small hole on each side.Put a nail in each hole.The bow should be facing the head of the nail.When the trap releases, the bow should come down and hit the nail on the head.You should drill four holes if you're using a glow stick.The bow will hit the glow stick when the trap releases.
Step 7: The tent pegs and mouse trap should be painted.
Paint the mousetrap and pegs to match the surroundings if you want to camouflage your trap.Before attaching the mousetrap, you can paint the tent pegs.
Step 8: The fishing line has to be tied to the other tent peg.
Attach the line to the other tent peg.The peg is in the ground.
Step 9: The bait peg is where the fishing line should be.
The wire should be taut across the path.Tie it to the bait pedal from the back of the trap.
Step 10: A rubber band is used.
There is a rubber band on the peg and mousetrap.The rubber band will hold the tripwire.
Step 11: The mouse trap should be moved.
There should be a pop cap on each nail head.To arm the trap, pull the bow down.
Step 12: Leave it to keep your area safe.
The mousetrap will hit the pop caps when the tripwire is triggered.It will tell if a person is walking.The glow stick will light up if you hit it.
Step 13: There is a water bottle.
A bottle of 20 or 24 ounces is fine.
Step 14: The water bottle should be cut in half.
The bottle needs to be marked in the middle.You can cut the bottle in half with a hacksaw or scissors.The top half of the bottle is used for this trap.
Step 15: The edges should be smooth.
Sandpaper can be used to smooth the edge of the bottle.Duct tape can be used to tape over the edges.
Step 16: The balloon's small end needs to be removed.
Wrap the rest of the balloon around the bottle opening.It doesn't have to go all the way.It needs to be in a single band.
Step 17: Attach a piece of wood to something.
The Popsicle stick would work well for this project.The balloon band is wide.Round the edges.
Step 18: Add hot glue.
Put hot glue on the wood.Attach a piece of string to the wood.
Step 19: Take the wood and put it on the balloon.
The balloon should go across the band.On either side, let the strings go down.Pull the ends from the inside of the bottle to the outside.
Step 20: A knot is tied in the thread.
The inside of the bottle has a knot in it.
Step 21: Attach stakes to each other.
Three pieces of wood are longer than the half bottle.Glue or tape them together.They should stick out past the mouth.You can stick the tripwire in the ground with these.
Step 22: The Trigger can be created.
A small piece of wood can be used to close the bottle.The string should be tied to the end.
Step 23: The tripwire is created.
Attach the other end of the string to the small stake.There is a Popsicle stick that will work for this part.
Step 24: The bottle has a knot in its mouth.
Put the stick under the knot.The bottle has wood in it.
Step 25: Take the bottle out of the ground.
The stakes should be pushed in the ground to be careful.To prank your friends, you need to disguise the trap.You can't hide the top of the bottle as it will release your trap.
Step 26: Put the string out.
Wrap the string around the stake.Take the stake out of the ground.
Step 27: The trap should be filled with flour.
Water or flour can be put into the balloon trap.
Step 28: Someone should trip the wire.
The balloon will throw the flour or water into the air if the wire is tripped.
Step 29: Get your materials.
You will need a clothespin, an electronic buzzer, a battery, two-sided pads, and a small piece of copper tape.
Step 30: The clothespin needs to be open.
To squeeze the ends, use the twist tie.You want to open the clothespin.
Step 31: Wrap the tape around the open ends.
Wrap the copper tape around one of the open ends.It needs to be Smoothed down to the wood.
Step 32: Attach the red wire to the wall.
The pad can be used.The red wire should be stuck to the copper on the top of the clothespin.
Step 33: Don't let the buzzer go down.
The buzzer should be stuck to the top of the clothespin.
Step 34: The black wire needs to be pulled down.
The clothespin mouth has a stick pad on it.Without the copper, put it on the side.Attach the black wire to it.
Step 35: The battery should be on top of the wire.
Stick it to the black wire with the negative side.Place the wire on the battery.
Step 36: A hole is made in a piece of cardboard.
The cardboard should be thin and long.Use a needle to poke a hole.
Step 37: The hole in the cardboard has a string in it.
You can use fishing wire.Attach a string to the hole.
Step 38: The cardboard should be put inside the clothespin mouth.
The twist tie should be loosened at the back of the clothespin.The mouth of the clothespin should be near the string side.To test the clothespin, pull out the cardboard.If it buzzes, you should see it.Take the cardboard out of the mouth.
Step 39: Attach the wire to the wall.
Use the pads to stick up the clothespin.The tripwire should be run across the doorway.On the other side of the doorway, tape it up.It needs to be taut but not taut enough to pull out the cardboard.
Step 40: Let someone know that the alarm is going off.
The cardboard is pulled out when someone crosses the tripwire.The circuit will be connected by the clothespin.The buzzer will sound.
