Hey everyone, I bought some crystal sand (sometimes also called glass sand) and recorded some crunching sounds. Took me a few tries to get some half decent footage... On the first try the sand didn't really "flow" out of the bag. Second try: memory card full. Third: unexpected background noise. That's the reason why there is already a bit of sand laying around at the start of the video. I hope you like it though.

Make sure to wear headphones :) Relax and enjoy!
