Instructables
This design is similar to The Office Booby Trap by PocketSized but with a new twist! Instead of shooting a sharp object at someone this scars the crap out of them when they shut the door !!!!

Step 1: Materials

Picture of Materials
- Piece of cardboard
- 2 Rubber band
- 2 Big paper clips
- Thumb tack
- Needle Nose pilers
- Piece of string
- Masking tape
- Balloon

Step 2: Assembly

- Take one of the paper clips and unbend it to 90 degrees.
- At the point loop it to form a circle (see picture)
- Now take the thumb tack and put it in the big loop on the paper clip.
- Twist the end around it a couple times to secure it.
- Now rip off two pieces of tape both about two inches long.
- Attach one on the bottom and the other one on the top as shown in the picture.

Step 3: The Base

Picture of The Base
- take the piece of card board and put the two rubber bands on it eack 1-1/2 inches from the end.
- Tape one of them on the ends to the card board.
- on the opposite end tape the paper clip / thumb tack down as shown.

Step 4: The Trigger

Just like The Office Booby Trap, Part 2 has some what of a trigger.

-Take the other paper clip and cut a 2 inch piece off of it,
-Bend one end like a hook and one end as shone in the picture
-On the rubber band that is not taped down hook the trigger on. Make sure the rounded top point is facing the paper clip / thumb tack.
-Tape down the rubber band close to the trigger.
-Now take your needle nose pliers and crimp it to the rubber band.
-Take the string and tie it twice near the middle of the trigger.
-Now pull the other rubber band over the thumbtack / paper clip as shown.

Step 5: Set Up

As in the Office Booby Trap you need a place to set it up at. behind an OPEN door is best.

-Now tape the Trap down behind the door.
-Tape the string to the door.
-Set the trigger.
-Blow up the balloon and tape it close to the thumb tack.
-Now all you have to do is wait for your unsuspecting victim. Hahahahaha!!!!!

hey this was a cool trap but is there a *Painful* trap ?
yes you have a wonderful question... is there a painful trap?
thanks looks like we are having the same motive on the *painful trap* :P
yeah i mean whats the point of having a booby trap that doesn't make people ruin their pants or actually really hurts.
lol agreed
haha ur 100% correct ! :)

Really cool idea but you can get the same effect by taking the explosive out of a party popper and taping the string to the door and the lil "popper" to the frame (this can leave marks) but its louder and leaves no evidence other than a bit of tape and string .
this a late response but, u can fill it with airsoft bullets or knex peices or anything else, then rig it so that wen somebody walks on something, it goes off and hits them
sweet idea

If you made the base heavier, you might be able to use this on floors that can not be taped to very well (carpeting?)
