Squirrel Bones Glow Under UV Lights

In this video, we explain why squirrel bones glow under UV black lights. This is true exclusively for one species of squirrel - the eastern fox squirrel. In the video, we explain why this happens, and show what a squirrel skull looks like as it fluoresces under a UV black light. This video answers the questions:

What animals fluoresce under UV light?
What animal bones fluoresce under a UV lights?
How does fluorescence work?
What is the science behind fluorescence?
Why do some things fluoresce?
What do squirrel bones look like under a UV light?

The sound effects and delivery makes me feel like I’m watching an adult version of a kids show 😂
Pretty cool.

Look at parakeets under a black light. I did this by accident in the 80's not knowing they reflected beautiful colors!

Squirrel skulls looks like if they were extinct, we'd think they had beaks 😂

As a non-English speaker, I approved this kind of narration in shorts, very short and very understandable.

I’m so glad we got 2 seconds of actual squirrel skull glow

[xnasunimc]

I love how slow the narrator is talking. It makes it so much easier for me to understand

[cogadoga]

Edging us with the knowledge of a squirrel bone glowing until the end of the video and forcing us to learn is genius bravo to you sir

[urbanshadow]

I'll make sure to test this out with my collection of squirrel skulls when I get back home.

Why are these videos like actually calming, it’s like reaching a checkpoint

This is so much better than just showing that squirrel bones glow differently under blacklight. Explaining how the actual process works, followed by what you usually expect of the experiment, and then following it up with the actual results *after* knowing what is happening is such a great way of educating. I always see people showing something weird first to grab attention, and then it's a 50/50 whether or not they explain what's happening. I found myself actually engaged in the experiment and wanting to learn what color squirrel bones glow, and I wish any formal institution could have grabbed my attention like this. Or maybe it's my fault for not getting into biology 😅. Either way, it's an incredibly enjoyable video so I leave this long comment so that perhaps this video gets to even more people

This is so cool! I love how this guy talks and teaches me things, calmly and simply.

[GeekExtremist]

The voice and sound effects bring back memories of old PBS science shows for kids. I love it!

[Artpad-yf]

This is so fun yet entertaining you’re voice is so calming tho

Why is this giving that one adorable show called the sound collector

[RibsawTheAllo]

That's actually really cool since that pink is a very rare color throughout the natural world

[AnshuKumar-rtvq]

That's a squirrel's head? I am convinced dinosaurs looked cute instead of horrifying

[hypercube]

Love the PBS vibes. My very tired brain still wants to learn but is overstimulated and overworked. This is what I didn’t know I needed.

[crazyhusbandos]

tbh i like how educational yet mature the person sounds

[Onaneehsyu]

So what did evolution do to you?
