In this tutorial, we learn how to pick a combination lock using a soda can. To begin, have your lock next to you and an empty soda can and scissors. When your lock won't open, cut the soda can in the middle so you have a small square. After this, cut off strips, then measure the size of your pinkie on the foil. Next, cut the foil out so it's the exact size of your pinkie and then stick this piece of foil into the lock. Move the foil around until it comes undone and you will have the lock unlocked in just a few minutes!
