Hey, i have a few of those prize crimbo cracker locks lying round, and i had a go at one. i could not work out how it works, or how do open it, and if i apply pressuse with the tention wrench the plug just spins around as far as u can be a***d to turn it (u can do 360 degree spins as much as you like). in the end i got pissed off, ripped off the bottom, and shoved a screwdriver up it and twisted and it opened

. any1 got a better soloution then mine?
