Mesmerizing Shockwaves in Your Window Screen (18,000FPS) - Beyond Slow Motion

BeyondSlowMotion - 2017-12-08

I was hanging out with Kevin Kohler (The Backyard Scientist) a while back and he brought up this really awesome effect that he noticed early on in his YouTube career. It's basically a grid type shockwave that results in a star shaped shockwave! So cool!

 At the time he only had an old Casio camera for slow motion, but it was just enough to be able to barely see this effect. Brandon had his Phantom v1611 with him, so we opted to shoot this in 18k fps just so see what it looked like. This was straight up mesmerizing.

it looked like it was trying to go through the matrix... denied

Sweet stuff dude, way more awesome than I expected!

I love back yard scientist lol

BeyondSlowMotion - 2017-12-08

Gabriel Contreras Me too!

Mohammed Mreh - 2017-12-08

Yep. Let’s throw apple AirPods case for this test. It’s only 159$.

BeyondSlowMotion - 2017-12-08

Mohammed Mreh Yup! :) Haha Though the Airpods are pretty tankish. Using the same ones right now as I work out actually. :)

I like how they used an airpod case to do it

BeyondSlowMotion - 2017-12-08

+MADMAX Would you expect any less from a GizmoSlip alumni? ;)

Great video again! Very interesting on how the pattern is formed!

BeyondSlowMotion - 2017-12-08

+Joe Fleming Right?! So interesting.

Awsome

Water is the absolute BEST in slow motion!

Coby Rosales - 2017-12-10

While you use a AirPods case to make a video am try a lot to buy one or make my dad buying me one 😔😭😏

BeyondSlowMotion - 2017-12-11

+Coby Rosales Haha I feel ya. If it helps any, I didn't break the airpods. Actually using them now as I type!

Sweet video, but why the loud and awful music?

Nice demo of circles in the taxicab metric! https://en.wikipedia.org/wiki/Taxicab_geometry

Zurar - 2017-12-12

I would be really interested to see the pattern if the screen was installed at a 45 degree angle to the frame, instead of a [near] perfect 90. I also believe that the pattern would differ, slightly, when using a square frame vs a rectangular frame. Both would be great follow-ups to further examine the results. Another test would be to pull the screen tight in a more diamond-shape over a square frame, rather then keeping the mesh perfectly square. This would likely differ greatly between a square and rectangular frame, as opposed to the square mesh, which would be a more subtle difference, if any.

a beanie in florida.....guess that makes sense. Nvrmnd

BeyondSlowMotion - 2017-12-09

+dustinallenphoto Haha For me a beanie makes sense just about anywhere. :)

sahil89 - 2017-12-09

Did you delete my comment about video pixelating due to compression? Pretty weird that you will decide to delete comment which basically explains why video pixelates right when slow mo starts.

BeyondSlowMotion - 2017-12-09

+sahil89 No I have not deleted any comments. That's weird for sure. Not sure what's up there.

sahil89 - 2017-12-09

Well, I had subscribed to your channel through Physics Girl. Always wanted to see your channel grow, hope it starts getting million views. All the best.

unalx - 2017-12-11

Not so sure about the explanation, they should do the same experiment with a circular frame for the net, to make sure it's not a boundary effect.

BeyondSlowMotion - 2017-12-11

+unalx Good thought! However we know it isn't a boundary effect because we can see the impact spread fully isolated from the edges of our screens. The effect also starts the same way no matter where we hit the screen. Each of those shots was impacting a whole different part of the screen, but cut together for continuity. Plus the star shaped shockwave's diagonal corners are essentially rounded off in a logorithmic curve that becomes more dramatic the further it deviates from the vertical and horizontal elements of the mesh pattern. It is all very different behavior than for instance the ripple in a square bucket of water when you drop a pebble into it.

There are a lot of tell tale signs that the effect is caused by the mesh rather than the frame.

Fickleheaded - 2017-12-09

Kevin sold this house maybe 4 months ago. This video is soooo old

BeyondSlowMotion - 2017-12-11

+Fickleheaded Yup! I've got a library of videos I have been stacking over a period of time. Will be putting out a bunch of videos in the near future hopeully.

yup

Nice but I need a sickbag for the drivel masquerading as music...

G E M - 2017-12-12

better then the noisy garbage on your page

Andy Raeburn - 2017-12-19

None of that was written either by committee or uses the ascending millennial whoop scale. Nor does it tremulate in and out in an effort to affect the listeners breathing patterns, as per post MK Ultra recommendations. You've been brainwashed Sahn.
