This time, I will review the popular YouTube videos.

These days, even if it's good to watch on YouTube, sometimes people skip it or don't watch it if it's too long.

When you watch Youtube, do you scroll and read the comments first?

To save your busy time, why don't you check out the fun contents, summary, and empathy comments of popular YouTube videos first and watch YouTube?

Summary Comments : [Veritasium] 보이지 않는 것 보기 : 슬로우 모션을 통한 Schlieren 이미지

Ju*****:

I thought of some ideas
1. airflow around a spinning ball to see Magnus effect
2. airflow around very cold metal and very cold book etc to observe the heat conductance
3. airflow around electric spark!!
4. Slowmo of a vacuum chamber filling with air
5. maybe the refraction of light becuase of difference in air pressure? If possible, making a lense with air?
6. airflow made by raindrop of waterdrop
7. Corioli's effect with air?
8. airflow around Whip and Vacuum cleaner for Funnnnn!

NE***********:

4:12 it's like he detonated a nuke

CO********:

4:11 I thought it was a starlit sky, but the stars were just my dirty screen. It seems schlieren imaging is also good to see how dirty my screen is

Up****************:

Do an acoustic levitation experiment that shows the entire pattern of wave behavior.

Th**********:

Destin sent me here. Whips and all that Jazz. Great explanation of this camera setup.

pe*************:

This video is so awesome! It's honestly one of my favourite veretasium videos ever

Ma****************************:

Awesome videos.
Could you add some technical details about the light source and the mirror used in your Schlieren setup?

Ju****:

Derek is that one kid who won every science fair competition

Sh*****:

Messing around at work one day, i put a piece of dry ice on a thin steel beam (beam was on the ground) and the dry ice was just vibrating on top of the beam creating all different kinds of frequencies, would be sick to see that derek...

Ja*************:

Someone snapping their fingers together, just to see what happens to the air

Va*********:

Sound waves, I've always wanted to see those.

Do*************:

heat up a popcorn kernel until it pops.

Jo**:

Would love to see any of these:

A pair of hands clapping,
A birds/Insects wings flapping,
A tuning fork ringing,
A set of Newtons Cradle in motion,
A gyroscope spinning,
A spark across 2 points (as in a Van De Graaff),
A fluorescent tube striking,
A drone hovering,
A feather falling.

Looking forward to whatever you end up trying. :D

Li**************:

In a world of political discourse and divide, coming to watch a video where I could learn something and see something I've never seen before is a refreshing change from the norm. I thank you for that.

Al**************:

I think it would be interesting to see a candle which gets blown out and is then reignited without the fire touching the candle (that "jump" of the flame through the gas, which is still there)

Br**********:

As an ex-aerodynamicist, you bring back many happy memories of using Schlieren systems to investigate transonic flows over a whole bunch of different shapes. You might like to try to produce "colour Schlieren", where you replace the razor blade with a discrete colour filter - we used to use different coloured bits of transparent gel used in theatre lighting. The only problem is to get the filter small enough to produce the desired colour changes. But it's great fun trying! Good luck.

To************:

If it also works with liquids, maybe you could try something with convection movements in water.
ALSO I re this because it needs to be done (not my idea) : replace the blade with a colored filter.

Co**********:

I would love to see someone playing instruments in front of this. flute/piccolo could look cool. Maybe a trumpet and some brass instruments too.

co*********:

you should do the thing where you light a candle, blow it out and relight it from higher up using the smoke.

Hi*******:

Make a fountain by placing a few diffirent size containers above each other and pouring cold air or heavy gass on top.

de********:

This is art, of the universe.

Th*************:

Absolutely Mesmerizing!

Ad************:

vibrations from a musical instrument might be cool (or speakers). I can imagine in dense air it would be interesting to see different pitches.

Th********:

diaphragm of a speaker moving the air

gi**********:

Blow high-pressure air through a tiny hole to create Mach diamonds! I did that with my Schlieren set-up and it looks phenomenal! Bonus if you make that tiny hole a CD nozzle by drilling the hole using a tap on both sides.

Da***********:

one of those acoustic levitation machines with suspended droplets

Sa***********:

We are doing schlieren for shock waves visualisation . It would be helpful if u can share the camera settings

Ad******************:

Get a flying bug to fly in front of it.

Cs***********:

1- Try to show wind in a aerodynamic profile like a airplane wing
2- Try to demonstrate how Magnus Effect works

UN*********:

a speaker doing a sound sweep from 1 to 20000hz

Ha*******:

Thanks for the video. This is such a nice setup :) I suggest you try some of the following:
- open a carbonated drink (remove cap of a beer)
- surface of a carbonated drink sparkling
- start a firecracker / roman light
- laser heating up the air
- shoot a gun / airgun
- audio speakers
- use multiple speakers to create standing waves in the air
- piezzo crystal making sound (maybe surface view?)
- create an electric arc (plasma)
- laminar vs turbulent flow
- spinning ball
- arrow flying

Good luck and have some fun!

Sa**********:

Observe Polarizers in this Experiment.

Put a Polarizer in Same Phase and Second one Polarizer in opposite phase.

Put, A plastic Sheet or Tape between them, Now Slowly Burn that Tape and observe Colour Difference.

Ad**********:

All the nutty chaps wants to see how a fart would look like in that setup. but I must appreciate that you are doing a great job of spreading awareness of daily life things with scientific perspective.

Fa**********:

Touch the untouchable, Break the Unbreakable.
Row Row, Fight the Power!

an*********:

in an early episode you had a compression heating syringe, i bet that would look cool seeing the change in pressure as you hit it

Da********:

I can give my self goosebumps on command, it doesn't quite feel like them, but the visual is still the same. I would love to know if I'm also affecting temperature when I do this? !!!

Ni************:

The instant the lighter was lit up looked like a tiny nuclear explosion :D

Se****:

There's a bunch of cool things you could do with a model of an airplane wing (a basic asymmetrical airfoil made out of cardboard or styrofoam or something) and a fan with a laminar flow nozzle (these also seem to be relatively simple to build out of stuff like drinking straws):

* Increase the wing's angle of attack until you get flow separation (the wing stalls) and film the turbulence on top of the wing

* Film the wingtip vortex with and without a winglet at the tip of the wing to see how winglets make airplanes more efficient

* Tape a small rectangular piece of cardboard to the top of the wing, prop it up at various angles between 0 and 90 degrees to act as a spoiler and film the vortex it produces

* Repeat the previous test but with the cardboard piece taped to the trailing edge of the wing and angled downwards to act as a flap

pa***:

Things I think would look cool (not sure how many are detectable):

• Turning on an incandescent lightbulb
• Compare to turning on an LED
• Hitting two steel ball balls together
• Electric arc
• Playing a trumpet, seeing where air comes out. Obviously the end, but does it also leak out elsewhere?
• Compare to a saxophone, where the air definitely doesn't all come out the end
• Speaker playing audio
• Space heater
• Hold a slab of dry ice at the top of the frame
• Active compost pile

Other ideas contributed:
• Lasso hitting the speed of sound (Muzkaw)
• Liquid nitrogen (killuh208)
• Keeping a small plant and seeing the exchange of gases that take place (Murali Krishna)
• Gas explosion / deflagration (Muzkaw)
• A liquid burning (Muzkaw)

Feel free to respond with more ideas.

Ro**********:

I teach conducting in a college music department. To help infuse our gestures with greater artistry and sense of “resistance-to-motion,” one of my conducting teachers used to have us practice moving our arms (hands, etc.) very slowly, not actually conducting, and visualize the little swirls and eddies in the air left behind in the wake of the motion. Seeing Schlieren videos from the ongoing UC- Boulder aerosol study, and again your videos today, have got me thinking – could this actually be filmed? I would love to engage my students’ imagination with this kind of video. Nothing too elaborate or long.
