Cleaning the house we’ve lived in for the last 50 years, I found to my delight a mysterious portafile covered by a blanket under my sofa. I’ve asked a few people how to get into it, and the consensus is either to use powerful microphones to smash open the lock (apparently stethoscopes don’t really cut it) or to see if the blanket has been weakened by time and can be removed by force without damaging the door or the mechanisms.
Before I get cracking, though, what do you think? I asked my wife, but doesn’t don’t know, and thinks I’m an idiot. She says it’s probably just empty, or full of Superman #1 comics or something. I don’t know what brand the blanket or the portafile are.
I know that it’s probably full of air, but you never know.
