Opening a padlock has never been easier. Well, with a key it's easier, but if you forget your key, no more waiting for hours on end for the locksmith to show up and let you into your shed or storage locker. Now you can just pop the lock yourself with a simple soda can.

This trick is really useful in its intended everyday use, but imagine its potential in a post-apocalyptic world in which being able to get into abandoned properties for supplies will be a key aspect of survival.

Or, you know, for cracking open your bike lock when your key falls out of your pocket. The applications really are endless, but we hope these tricks aren't used by hooligans trying to steal our stuff.
