"Whether you’ve lost the key to your own suitcase and need to get it open in a hurry or you’re trying to plant some contraband in your dodgy roommate’s bag, this clever hack has to be seen to be believed."
"Watch the video above to see how a pen can be turned into a suitcase cracking tool. In the demonstration they use a ballpoint pen to exert pressure on the zipper of a suitcase. The pressure causes the teeth to separate, effectively opening the suitcase.
The secret sauce in this hack of dubious ethics, however, isn’t the pen (you could always slice a suitcase open with a knife if you wanted in that badly after all) but in the zipper mechanism itself. Zippers are self healing and if you run the zipper pull (still securely locked to the other pull, we might add) along the zipper track you’ll reseal the suitcase as though you were never there."
