This is the sound of someone shaking a kinder surprise egg trying to guess what's inside (like in the tv advert). This is a simple sound that i recorded with a zoom h2n handy recorder. I just cut the extra recording parts, and added a noise reduction effect to clean it in audacity.
Running a corkscrew several times rapidly along the edge of a wooden desk. Recorded with minidisc and condenser mic, indoors, 6" distance. Background noise removed with audacity. Short, rattly hard noises.
I had a bunch of boiled eggs saved in a tupperware, and i was getting ready to record cracking and peeling some, so i decided i may's well record a little rattle too.
