A tripwire is a mechanical device.It's usually used in weaponry.In war, they are used to cause an enemy to fall and to trip a mine.They can be used for other purposes.You can use a tripwire as a prank or perimeter alarm.
Step 1: Take your materials.
You need fishing line, a mouse trap, ring caps, tent pegs, nails, screws, and rubber bands.
Step 2: The tent peg has a mousetrap on it.
The tent peg has a mousetrap on top.To screw them together, use a screwdriver and wood screws.
Step 3: The bait pedal is behind the trap.
The bait pedal is the part of the mouse that releases the trap.There is a hole through the mouse trap.Later, you'll tie a knot over the bait pedal.
Step 4: Cut out the caps.
Cut out individual pop caps if they're 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: Several times, release the trap.
When it releases, you need to see where it is hitting the wood.
Step 6: Hammer two nails.
There are small holes on each side where the bow hits the wood.Attach a nail to each hole.The bow should be facing the head of the nail as it swings down.When the trap releases, the bow should hit the nail on the head.You should drill four holes if you are using a glow stick.The bow will hit the glow stick when the trap releases.
Step 7: The tent pegs 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 must be tied to the other tent peg.
Tie the line to the other tent peg.The peg is in the ground.
Step 9: The bait peg has a fishing line.
The wire needs to be taut across the path.Attach it to the bait pedal by running it into the back of the trap.
Step 10: A rubber band can be used.
There is a rubber band on the peg and the mousetrap.The rubber band will hold the tripwire.
Step 11: There is a mouse trap.
There should be a pop cap on each nail head.To arm the trap, pull the bow down.
Step 12: Leave it to protect your area.
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 when hit.
Step 13: Remove the bottle from the water bottle.
A bottle of 20 or 24 ounces is fine.
Step 14: The water bottle needs to be cut in half.
The bottle has a mark on it.To cut the bottle in half, use a hacksaw or scissors.The top half of the bottle is used for this trap.
Step 15: Make sure the edges are smooth.
Sandpaper can be used to smooth the edge of a bottle.Put duct tape over the edges.
Step 16: The balloon has a small end.
The rest of the balloon should be stretched over the bottle opening.It doesn't have to go all the way.It can be done in a single band.
Step 17: Attach a piece of wood to something.
A Popsicle stick would work well for this project.The balloon band is wide.The edges should be round.
Step 18: Attach a string with hot glue.
Attach the piece of wood with hot glue.Attach a piece of string to the wood.
Step 19: Take the wood and put it on the balloon.
The balloon should travel across the band.On either side, let the strings go down.Go from the inside of the bottle to the outside with the ends.
Step 20: There is a knot in the thread.
The inside of the bottle has a knot in it.
Step 21: Attach stakes
Three pieces of wood are longer than the half bottle.Glue or tape them to each other.They should stick out past the mouth.The tripwire can be stuck in the ground.
Step 22: The triggering event should be created.
A small piece of wood can be used to close the bottle.Attach the string to the end.
Step 23: The tripwire should be created.
Attach the other end of the string to the stake.A Popsicle stick can be used for this part.
Step 24: The bottle has a knot in it.
Put the stick under the knot.The wood should be spread across the bottle's mouth.
Step 25: Place the bottle in the ground.
The stakes should be pushed in the ground to be careful not to shoot.To fool 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: Take out the string.
Wrap the string around the stake.The stake should be in the ground.
Step 27: Add flour to the trap.
Water or flour can be put into the balloon trap.
Step 28: Wait for someone to trip the wire.
The balloon will throw the flour or water into the air if the wire is tripped.
Step 29: You should gather 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 kept open.
The twist tie can be used to squeeze the ends.You want to open it.
Step 31: Wrap the tape around the ends.
Wrap the copper tape around one of the open ends.It should be smooth on the wood.
Step 32: Attach the red wire.
The pad can be used.The red wire can be stuck to the copper on the top of the clothespin.
Step 33: The buzzer needs to be stuck down.
The buzzer can be stuck to the top of the clothespin with the sticky side.
Step 34: The black wire should be stuck down.
The clothespin mouth has a stick pad on it.Without the copper, put it on the side.The black wire should be on the top of it.
Step 35: The black wire should be placed on top of the battery.
Stick the negative side towards the black wire.Attach the wire to the battery.
Step 36: A small hole can be made in a piece of cardboard.
The cardboard should be thin and long.Place a needle in the hole.
Step 37: The cardboard has a hole in it.
Use fishing wire.A string is tied around the hole.
Step 38: The cardboard should be 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.Go across the doorway.On the other side of the doorway, tape it up.It needs to be taut but not too taut to pull out the cardboard.
Step 40: Someone should trip the alarm.
The cardboard is pulled out when someone crosses the tripwire.The circuit will be connected by the clothespin.The buzzer will ring.
