While at Willingham, we also happened across this strange bubble. It was about 12mm in diameter, and didn't seem to want to burst. It was too clear to have been plastic. Could have been glass, I suppose, but it seemed too light and was sat perched on top of a blade of grass. We were too hesitant to touch it lest it burst. It was most peculiar. In this picture, you can see how many of us were crowded around it trying to figure it out, and in the centre my Canon A495, which performed admirably considering it was the cheapest obviously non-crap camera I could find. Yes, cheaper than any Samsung.
