The strange science of breaking into lockers

[weezerfan2001]

Just found out today that the HOS locker not only holds an extra HOS headset (very useful for traitors and goofballs alike), but an energy gun as well. Now, with this new found knowledge I naturally broke into HOS' office and stole the locker, but when I used my traditional method of breaking into lockers, plasma lightbulb bombs, it did literally nothing. To add to my confusion, after about 4 light bombs, I leave the room and return shortly to find the lockers been opened??? What could've caused this, and what's a more reliable method for opening strong lockers in the future?
