Thank you so much for posting this!

I've always been so fascinated with this phenomenon since I was a kid and would spend a long time looking at this lying on my back in the sun.

I remember telling an adult sometime and they said very authoritatively that light wouldn't bend noticeably at that scale and that it was probably some kind of optical illusion, and accepting that at face value.

But now I'm looking at it again and it's so fascinating and there's so much there – love this conversation! Especially pleased that there's no scientific consensus about this.
