Maybe you often lock yourself out of your own house, or perhaps you just want to learn how to pick locks to get a better understanding of security. If you don’t have a set of picks handy, Instructables user hailtothkngbby shows us how to make one using the underwire in a bra.
This trick is handy because it contains something you will almost always have with you (provided you are female or travelling with one).

Raking is a method of lockpicking in which you move the lock pick in and out quickly to move the tumbles (see the video above for a demonstration).
