The Curious piece of sand

We collected grains of silica from our sandpit and safefall last year after one of the children wanted to know how glass is made.

We used the microscope to look at them to see if there was anything interesting. There was, one grain moved by itself. We zoomed in on it as best we could but we never did figure out why it was moving when those around it weren't. Since we've been uploading video I thought I'd pop it up to see if any one knew why.
