Thanks to Lewis and Sandy, who spotted a beautiful, intense, double rainbow from my window during a non-contact period today. Luckily I had a polarising filter to hand and Lewis managed to capture some photos showing rainbows are partially plain polarised. Check out the photos below.

What a way to spend a non-contact. Thank you! I suggest you keep a bit of polarising filter in your pocket, just in case! Don’t pinch mine though John needs it for his AH Project.
