I saw these green chips as I went out for lunch yesterday. They were scattered all over the tarmac driveway.
As I squatted down to take the photos of this, a lady in a car next to it came down and asked me what were these. I noticed she is a regular at this place as I often see her parking her car there to eat her lunch.
I had no idea what this chips were but it sure wasn't from a car windscreen or window. I said that because once in a while, I do come across a pile of shattered glass chips on the road, presumably from shattered car windscreens and windows. They looked so uniformly cylindrical and weren't sharp at its edges and I wonder how it ended up there in the first. Alas, I should have collected some for decoration in my terrariums.
