Watch: How to Lock a Door With a Fork
Russ Chastain 08.30.16
This is pretty cool. With a couple of small modifications, you can use a simple dining fork to create a gadget that will “lock” a door that swings into your room.
It won’t do much to keep out bad guys; the Youtuber who posted this readily admits that it “is made to be a privacy lock.” And for that, it should work pretty well, especially since you can get a fork pretty cheaply (he bought his at a flea market for 25 cents).
I’m not gonna steal his thunder by explaining it all here; that’s why he made the video! Enjoy.
