here is how to make a lock pick so you can lock your friend in their room.
note: this only
works on the locks with little holes on them(see picture at end).

Step 1:

right, for materials you will need to have

bobby pin
pliers

Step 2:

now take the pin and bend into a L shape(see picture)

next bend top of L down so it looks like a sideways T

Step 3:

take the pliers and bend the bottom until it breaks off

Step 4:

finally use the pliers to squish little plastic ball off and bend back the tip making sure that it is flat.

yay! now when your brother locks you out of your room you can just pull out the pick, open it up and tell your brother that you used the force to open the door.
