Just moved house and am amazed at how many guitar picks have 're-appeared' into existence. I drop them, they bounce and roll against the laws of inertia and blink out of existence. I drop a pick one side of the house and it ends up behind the couch on the other end of the house! Plectrum wormholes! There were sedimentary deposists of picks everywhere during moving house. Removalists kept finding them, there was always one somewhere on the ground wherever boxes were being moved. Even after the old place was professionally cleaned I still found picks there when I had to hand back the keys to landlord. Im sure there were even 'dark matter' picks from my teenage years following me in orbit. I've dropped picks before on their edge and watched them bounce away repeatedly on the same thin edge across the floor. If only I could tap into the free energy stored in every pick!
