halflife decay analogue apparatus.wav

I placed about 200 small brass ball-bearings (2mm diameter)on to a "half-life analogy apparatus" (which I have access to but I've never see the like using a google search. Basically its a titled wooden box with holes. The ball bearings roll down some of which fall through the holes and are collected in a beaker. The remainder are collected at the end of chute. Anyway, I just like the sound and hope someone can make use of it !
I used a Zealsound microphone and recorded directly into my laptop using audacity. The sound is as recorded.
