Experiment

I was trying to imitate some wildcat type sounds, but what ended up coming out of my mouth was something that sounded more like a cartoon character's weird laughs/noises.

A few long, windy-sounding breaths over the microphone.

I grind and tap a couple of stones against each other and against the microphone.

I crumple, pound on, and blow through a piece of plastic wrapping.

I spray a can of compressed air at the microphone. The nozzle straw of it ended up rubbing against the microphone once, which produced an interesting noise.

I make a bunch of percussion-type sounds by hitting a metal pot and its lid.

Breaking a bundle of spaghetti in half near the microphone. I cleaned this one up a bit of background noise and gaps of silence.

The file consists of 7 variations of this rustling bulletin boards sound.

Dropping lentils into a plastic tub.
The file consists of two different recordings. The first sound pricklier and closer. The second (after about the half of the file) more particles drop.

It's a plastic tub full of lentils (those lense shaped peas?) in which i scoop up hands full of lentils and let them drop again. The lentils are very smooth to the touch.
