Fact-Checking this Viral Bottle Trick

Breaking the bottom out of a glass bottle by hitting the top is a challenging trick, but involves a ton of physics. The explanation is related to cavitation - a process seen in the Mantis Shrimp attack, head injuries and pouring honey!

Not that long ago, the bottle popping trick was used as a demonstration of "chi energy" by martial arts masters!

You can't be in every math and physics problems ever imagined
Euler: Yes, I can!

That's my Dad's footage of the Thresher Shark attack! What a surprise seeing that in a physics video.

You really have a great talent for communicating science, for making physics understandable, relevant, and a lot of fun. This episode was especially fascinating. Thank you.

If you were to spit outside at 60, 000 ft, you would have a lot more to worry about than your spit boiling

Ok, cranial cavitation bubbles is the most horrific thing I’ve heard today. That’s for sure.

There is a lot of research as I understand. I'm just stunned by the quality of the explanation.

The music at 6:19 is so perfectly synched and well chosen.

10:31, she says "that's it, that's all we got" with such an adorable disappointing expression, after throwing like 200 cavitation facts, and I must watch this whole video a couple of times more to get it all right 😅😅😅

[gardeninginthedesert]

I love the sympathy in your voice when you talked about head trauma. This isn't just physics, it's people who are suffering from this and you treated it in that way. Thank you.

[sangraal]

I'm a naval engineer so this is right in a wheelhouse and I just want to say that you did a great job explaining this phenomenon! it was also cool to see that this applicable to other fields and being used to help people instead of just being a pain for me.

[SourGir]

I love that you don't talk down to your viewers, but you're able to make your topics accessible and understandable to those of us who aren't in physics!

[williambarbre]

"tail-whip", "stunned fish", "nom". That gave me the giggles!

One of my all time favourite YouTube videos and top two Physics Girl videos. I rewatched this today after her friend’s update on Dianna’s health. Please get well soon. ❤

I've worked on it and I know how it works, yet it blows my mind.

[orfeassiozos]

Wow. This is definitely one of the most interesting things I've ever learned, for real. Especially the last fact about brain damage blew my mind (figuratively, thankfully).

[bsjeffrey]

the bubbles are the souls of murdered water fairies.

WE MISS YOU DIANA‼😥😥😥 PLEASE GET WELL SOON ‼‼‼💝💝💝💝💝

[ristoner]

This genuinely blew my mind. I've seen cavitation in the Mantis Shrimp and behind boat propellers but to see it in slow motion with the bottle trick was absolutely amazing!
