@wonderofscience I am a raptor fan, and an owl lover.

This video is beautiful.

Reminds me of this:

The sound of silence:

@wonderofscience @adamwulf Makes me wonder what it would look like if I walked through a cloud of helium-filled soap bubble.

@wonderofscience @tvaziri Fantastic reference! Planes create the same vortex motion. I discovered this during the supervision of a recent project https://youtu.be/dfY5ZQDzC5s?t=154

@wonderofscience wow!

@wonderofscience “…reveals wingtip and tail vortices…” and also makes the owl sound hilarious at kids’ parties.

@wonderofscience
I too put up helium bubbles, but still the owls get in!

YamakaziTaiga,

@wonderofscience am I on mushrooms?

JanGebauer,

@wonderofscience fascinating. Owl are just the best! 👍

@wonderofscience That is a genius idea. Did they manipulate the size of the bubbles to give them neutral bouyancy?

BillMcGuire,

@wonderofscience

very cool indeed.

KenzoFKC,

@wonderofscience Mesmerizing!

@wonderofscience Now we all want to know how to make helium filled soap bubbles. 🤣

mamainu,

@wonderofscience 😮 That is so cool.

pete,

@wonderofscience

Vortices always come in pairs because the total curl in the fluid has to add up to zero.

@wonderofscience okay sure the owl is cool but WHAT!! You can fill soap with helium???? That’s so freaking cool!!!!!

@2du @wonderofscience I'm not advising this but you can fill soap with methane and have all sorts of excitement. Or hydrogen, for that matter.

Inah,

@wonderofscience so that’s how galaxies are made
