Earlier this winter, I was out for a walk in our forest when I stumbled upon some blue pee in the snow. In this video, we find out why rabbit pee is blue in the winter.

wait wut?
The part about the pee turning from yellow/brown to blue after exposure to UV made me think of this NileRed video. I would bet that some of the same chemistry is happening.

I didn’t know that was a thing at all and im a huge animal nerd
Can't thank you enough! I always learn so much! Hope spring hits you soon!
Porphyrin turns blue in sunlight.
oh this was so good – very interesting! more please.
This sounds like an opportunity to make an interesting 'all natural' blueprint process. Feed rabbits buckthorn. Collect urine, and soak paper. Expose to sunlight through negative. Profit???
I love that the blue pee expert was so close by!! What are the chances? Also, you got a drone! 🙂
"Don't eat yellow snow, or blue, or red snow, or…"
A better phrasing is probably: "Only eat white snow!"
Or maybe even better: "Don't eat colored snow"
But then, what about black snow? Technically both white & black isn't "colors" (at least in some cases), but is a mixture of all or no colors, but i would still advice against eating black snow too.
So, again: "Only eat white snow!" ;P
Very interesting!
Because everyone know not to eat the yellow snow rabbits are hey blue snow cones
Holy cow, thank you Fred!
You’ve found the alien that eats bunny poop..
Lol just kidding
Sounds like an experiment for natural dyes needs to happen! Also accepting explanations from the chemists. But I do wonder what colors could be made with different mordants and fixatives
Miss your videos, glad your still alive and well.
Very interesting. I used to use european buckthorn to dye wool various blueish green. Lived in North Gower. Thank you for such a great video.
Your-A-Peein Blue Buckthorn
Bishop's Mills, I know that place I drove through it every Monday, and every Friday, On my way to and from work, refacing the Jones Falls Dam, back around 1990… I thought you were much further south than that!.
Always happy to see, that you uploaded a new video. Even if its out of the ordinary 😉
If he needs any chemistry samples, I'm looking for a thesis XP
Fantastic video I really really enjoyed the interview. What a curious heart!!!
More videos like this one please!
Feels like Adam Ragusea of outside
