The other day i was going over thetopic of theft/general stuff to be on the look out for with a friend and she tells me out of the blu that busting a lock (like those used on hostel lockers) is theoretically quite easy.
1. find said lock on locker
2. spray inside of lock with aerosol (apparantly bugspray works best)
3. hold flame under lock for a while
4. click. lock pops open
5. get away with lockers content
Guess its time to switch to combo-locks.
just a warning.
