Making an Aragoscope 

very cool video! i would not have expected the awesome results that you got. well done experiment! one minor thing is that a laser doesn't make a plane wave, they are typically gaussian waves which look like a spherical wave when you aren't close to the aperture. i hate coyotes too lol. keep up the awesome vids!!

This is the coolest demonstration of this that I've seen. Really nice.

"My shoes are 12 inchs long. Its very convenient." Cody, my man!

I love Cody's Lab, and his yard, and his greenhouse, and his buttery kitchen, and his truck.

That's crazy man, I hadn't heard of this until now. I LOVE SCIENCE!

Discovering this video in my subscriptions: "Coin As Lens?" Hmm? How? "Making an Aragoscope" What even is that? "Cod-" Oh it's Cody's Lab! Ok, I'll watch it.

This is the solution that Veritasium was looking for in his "is light a wave or a particle" video. Great that it worked for you! Edit: The name of the video is :"The brightest part of a shadow is in its middle" I highly recommend it!

in phase >:)

Nice job Cody! Many of my viewers pointed me to your channel - glad I found you!

Could you use the moon as the disc for a large space aragoscope?

was half expecting a jump scare at the end!

_IN PHASE_

Cody, get a Sony A7s and use the extreme(but still usable) ISO of 409,600. You could have a must shorter shutter and measure way more light.

This is so cool! Wish I had a camera to do this too. Thank you for this education, Cody!

It's so awesome that all these channels I watch are so bonded, friendly and supportive to each other.

Cougars scare me more than wolves or bears or anything in the wilderness really. If a cougar wanted to kill you, you would most likely be mauled before you ever heard or saw it. I had one following me for almost a half mile through the woods before and never noticed it at all, and it was right behind me, like less than 50 feet. And I was hunting, trying to walk quietly and paying close attention to my surroundings. The only reason I know it was there is because there was snow on the ground and when I turned around to head back the way I came there were cougar tracks right on top of mine all over the place. Scared the crap outta me. I could just shoot some wolves or a bear, but you can't shoot a cougar if you're dead before you see it.

Any sufficiently advanced technology is indistinguishable from magic.

Cody is going to make something so revolutionary that everyone will use it. I just know it.

We need to get you some metric boots. :)

Photons are waves, except when they aren't.

if youtube takes this channel down im gonna boycott the f out of it

Beautiful demonstration, sir. Thanks for posting this video.

I N F A Z E

Such an addictive channel. I love science and not too bad at it but i wish school sciences where this interesting. Fascinating stuff explained really well and its got me hooked! Keep it up Cody!

Captain Cody is back at it again with things that shouldn't be possible but he's God so it is possible.

I really liked the timelaps at the end. Very interesting to learn that a come can be a very powerful lenses

Holy shit that sensor is dirty. 😰😰😰

Thanks for converting distances, Cody.

And then the thunderous voice from Heaven said... I-N P-H-A-S-E )))

Your video made more sense and proved the concept better than the 2nd video in your description. you're kinda the diy youtuber of physics. experiments like these are great to try out yourself. just get the distances right and well i assume any coin would do the trick. I'd love to see a follow up video where you try to make some sort of gear where you can put the theory in concept . i can imagine it to be a difficult thing to make. just saying i believe you could :) if not i'd appreciate if you let me know why not. As footer just wanted to say i enjoyed your video's so much i really like physics but the school i went to didn't had the subject available(no teacher or enough students to fill a physics class). so this way i still learn why and how things work. hope you your channel keeps growing. best of wishes, Erin. P.s. : you inspire me allot, and i hope to learn many more things from your channel :D

Cody is probably the only youtuber i still watch even if his videos quality is almost unwatchable.

I am properly amazed by the Aragoscope. I learnt something new today.

Cool video! Never heard of an Aragoscope..

your seamless editing skills never cease to amaze me! seriously though your goofy edits are far more entertaining than a bunch of jump cuts, keep up the good science dude!

R.I.P Cody, I hope they find those Coyotes.

Are you the first to do this successfully? Heard about the concept before and had a look for basically a video like this and I couldn't find any! Great vid Cody, only RU-vidr I have notifications on for

Hey everyone, cody's made a backup channel due to community guideline strikes. "Cody's lab backup" is the channel so go check out his update video!

had never heard this diffraction technique before.... thanks for teaching it to us... cool as always!

Araragoscope Sorry, I stuttered

Some of the most educational videos found on the web, and still only 1 mil subscribers. Keep up the amazing work, I love Cody's Lab

I N P H A S E

Fascinating demonstration!

HAH even Cody's feet are calibrated :D not in SI units though :/

Was anyone else waiting for a jump scare at the end of the video? Great video as always, Cody! I had previously heard of this phenomena, but handn't seen it practically demonstrated. Impressive!

What I like about you and your videos are they're so down to earth.

can you make a schlieren camera? where you can see air current

Very nice demonstration

"Focal lenght measurements"? I wish you told us that too! I mean i want to know how to do that measurements. The formula for that or the maths? Okay i seek more, like you say so. Really surprising this idea. Thanx!

I said to myself “how does that work, please teach me cody” when i saw the thumbnail. You’ve taught me more about science then ive learned in my entire highschool and college career so far.

OMG! You're encouraging people to experiment with photons. I have to flag you!

Your love for science will be an inspiration for generations to come! And yeah this was an amazing experiment or idea!

Do more mining videos!

Funny that I thought about interferences of visible light recently. That's a quick and nice demonstration of the concept AND it may be useful for sunspot observation with a camera.

I've looked thru dozens of comments and seem to be the odd one out. Whenever you said "you can clearly see..." I couldn't. This is interesting because it seems to be the converse of a pinhole camera, which is a "wide angle lens". It's very easy to get clear fairly detailed images from that. Will you follow this up to get easily visible images from this, cos all I've seen here is a very low contrast blur which other commenters seem very impressed by and leave me thinking there must be something wrong with my eyesight?

Fascinating & wondering what a laser pointer would produce . Thanks again Cody and best wishes .

Wow this is interesting. Something new for me that still is pure physics. This is really new knowledge for me, more insight! Nice, as always! And greetings from the netherlands (aka Holland)

Great!! I am surprised that such a technique to magnify distant object exists. Awesome work!!

It would be possible to use the moon as the dark disk? How powerful would be such a telescope?

Thanks Cody. Fascinating! Couldn’t see anything until you enhanced the brightness. How have I gone most of a lifetime without ever hearing the nam 'aragoscope'? If your shoes are about 12 inches long, then that's about 30cm. No need to use Ye Olde 1835 British Imperial units at all: 100 shoe lengths is 30 metres.

Hey everyone, cody made a backup channel due to community guideline strikes. "Cody's lab backup" is the channel so go check out his update video! this channel is facing being deleted and he cants even post a video to warn people!

It is not cody's lab. It is great cody's lab. Great man.

"IN PHASE"

Always knew that light was a wave but had no idea you could do something like this with it. Great video man

IN PHASE!

As a electroptics student i must say this is simply the most impressive demonstration of light diffraction I've ever seen！No hard Maths involved, just plain old physics！

I should be doing homework

Wave particle duality. Nice! Haven't seen it demonstrated this way.

95% of this video is pure darkness. Cool.

And I thought this was going to be a "boring" beryllium lens for IR photography you continue to impress sir.

Love the new intro cody!

You finally cover the science of photography! Wooo! Try processing some film, it would be a great addition to the videos about silver chemestry.

I'll try my odds with a coyote than a cougar any day of the week. I had the privilege of being chased by a cougar about 8 years ago while I was at work on night in the TX panhandle

man i can't believe how much I love your videos, you explain so well. Thanks!

Do you get as much work out of that bulldozer as it gets out of you?

You never cease to amaze and teach me something. Great stuff!

*converts 12 inches to 1 foot*

I was expecting a jump scare. Great video as always Cody!

Wait... $1 coins do exist??

Brilliant. Keep up the great work Cody, it's much appreciated.

Okay, so usually Cody's videos are about things I know at least something about and already kiiind of understand, but I really like to see applied practically. (Either that, or I cringe and hope he doesn't lose a finger, or worse). This was completely new to me and, other than the double slit experiment, even the basic theory is something I've never even read about. I love that. Thanks Cody. (Also, thanks for not endangering any digits in the making of this video).

Nice intro

That is the most incredible thing I think I have ever seen and I thought I had read up. Thank you. Pleased you are back online.

Hi cody! Big fan, longtime subscriber. I REALLY want you to meet/collab with "styropyro" here on youtube. Make this happen! I've already said the same thing to him, and he was down to do it. DM/PM whatever you guys do on youtube. Make it happen! Best regards, sweden.

Wow. PRIME QUALITY. So glad you (or the algorithm)brought this one back up. P.S. Thanks for the follow up resources. It allows BINGE second and third course consumption, before dessert. Thanks again.

Bro, you got more than 4k a month on patreon, could you PLEASE get a better camera?

Thanks for doing what you do, very interesting to watch your videos.

I would like to thank you cody, for inspiring us to study more science! Ever since i watched your video i enjoyed doing chemistry and electronic projects. I learned how to electroplate metals using copper acetate. I also learned alot of chemical processes which helps me with my lessons :) more power to you and your channel :)

Cody...you are such an amazing person!

Man you have a great mind and to also recommend other great utubers out there is being a great team player. I like your ideas

Wow Cody what an amazing backyard demonstration.... Can you show us the experiment that's similar to this which shows the speed of light?

Great demonstration!

Nice video, and thx for the units in the corner it helps a lot to understand what you mean.

This is my favorite RU-vid Channel. Thank you.

Very interesting effect to see. I've read a little about this kind of lens, but not seen one in action before.

Excellent video there Cody, I didn't even know of this effect until I tuned in today, lovely work there man cant wait for your next post :). StAsh.

You're an inspiration Cody. The literal and practical definition of the american dream. I love you.

The laws of physics with this BIG BANG are amazing. Can only imagine how they will be perfected when the big collapse happens yet again creating the next one... One of the smartest RU-vidrs.

I learn more about scince through Cody's channel then I have in my whole life. :)

You never fail to amaze me! great work!
