Q&A for How to Make a Beginner Boobie Trap

Hide your real diary and make a fake one to put where the real one usually is. Fill the fake diary with paper dots from a hole punch so your sister makes a mess when she opens it.

A similar trick is putting the film on the doorway so when someone tries to walk through he will get caught and be annoyed.

Whenever she says a word, make an obnoxious noise. Keep doing it until she tells your parents. Stop for a few minutes, then start doing it again.

Tell him that you're working on a huge surprise, and that if he comes in, he'll be sorry. If that doesn't work, then repeatedly put a plastic cup filled with water on top of your door. If he keeps getting wet coming into your room, he'll eventually give up.

Set up something that will hurt their feet if they come in (but nothing too bad), such as marbles or Legos. Put them by your door, and when someone comes in without knocking, he/she will be very uncomfortable.

A person could slip and fall on it, and potentially really hurt themselves, so I don't recommend you do this. It might also attract ants or other pests.

One good prank you can do is the Saran Wrap prank, when you put Saran Wrap in a doorway, and the other person walks right into it. It's funny, and it's not messy. There's also the whoopee-cushion prank where you put a whoopee-cushion on a chair or couch, and when a person sits on it, the whoopee-cushion makes a loud fart sound.

You can hide somewhere in her room and watch her, set up an iPad or phone to record her, or look around for her diary or journal and read it.

You can tie fishing line to the door knob and then tie the other end to a paperclip/rubber band gun. When people walk in, it will shoot at them.

Ask Siri or Elexa to say "Stop touching me!" when the password is entered ,and put a horrifying picture on the screen. Leave your phone out when someone nosy is in your room (like a little sibling, parent or guardian). Be prepared for a scream!

All you need to do to ensure that they never come back is call the police. They can't break into your house if they're in jail.

Use a small circuit board and follow the directions on it. Then hook it up to the door, and then you're finished. When the "intruder" walks into the room, they circuit board will snap, setting off the burglar alarm.

It breaks when somebody enters the room, alerting you that an intruder was in your room.

If you put tape over a faucet, it would most likely fall off. What you need to do is get a dime and tape it where the water comes out from the faucet. Make sure to leave a tiny space so water can spray out at your victim.

Try printing pictures of monsters or clowns and mixing these into the binder with the documents.

You should call the police immediately.

No. The tape will come loose. I suggest nails or tacks, with string or twine or something wrapped around them, extending to the other side.

Place marbles everywhere in your garage and driveway. But in the driveway put them under the car.

Just buy a raccoon proof trash can.

Prop a door open slightly and balance a bucket of water on top of it. Call the person outside urgently and when he opens the door, the bucket will fall and splash on top of him.

Tie a piece of string to your door knob and nail a U nail in the wall right next to where the handle is. thread the string through, and bring it over to a chair set a few feet away. Tape an airsoft gun or Nerf gun with to the chair, and wrap the string around the chair and around the trigger. Make sure the gun is tightly secured and the chair is weighted down. If done correctly, opening the door will pull the trigger. Be sure to aim the gun at where his head will be, and load 3 airsoft BBs in for maximum shotgun damage. I know it sounds confusing, but I've done it. Super entertaining.

Tie a rolling hitch in a loop of a rope, then wrap the rope around the overlap and end with a clove hitch.

You can use any of these booby traps, but you might get in trouble. You should just tell them that you need some privacy.

A fat man catcher! Place a large box below the chimney. Don't light a fire, though!

You can put a long string of bells on the ground, then cover them with leaves so that they make sounds when touched and are easy to remove again. Or you can make the dirt wet so that it will leave prints on the ground and soil on the intruders' shoes, or just dig a big hole.

Tie fishing line at the very bottom of the door using tape (one end of fishing line to one side of the door and the other side to the other side of the door). She won’t even bother to look down as she falls down right smack on the floor. I recommend doing this on a door where there is carpet on the room behind the door so she won't actually get hurt.

Set one of the above traps, such as the nerf gun idea.

Don't do that. Someone could slip and fall and really hurt themselves.

You can put plastic foil on the ground and put clear glue on top. This, however, doesn't work after a while, so you have to make sure your target steps in the trap as soon as you finish.

When the door opens, the tape will rip off one side. When you come back, you can check to see if it is still attached. Put the tape on the top of the door and make sure to put it on the outside, where you enter, so you don’t trigger the trap yourself.
