How do you make a home made door lock?

Question

I heard there was a way to make a home made door lock, nothing that you have to s***w into the door or anything permanent like that, but something cheap and easy to do that will keep my sister out of my room(wedging things in front of the door don't work)

Answer 1

The best way is to get a broom stick and cut it down a little shorter than it is and then mount a piece of wood on the end going perpendicular to the broom stick.  Prop this under the door handle and then put the other end on the ground.  It will take a "big sister" to get it open then.
