The fact that the image from a magnifying glass is just the image of the sun is so obvious and unsurprising. Yet it's never crossed my mind because the sun is "always" round.
It's upside down too. Take a magnifying glass, point it towards a light source like a window, and focus it on a piece of paper. You'll see an upside down image.
I once discovered this as a child while attempting to burn a piece of paper with the light from the ceiling. When I focused the beam, I just saw flipped picture of the coiled light bulb on the paper 😂
@@tolep well it can be right side up or upside down, it depends on whether the surface you're projecting onto is closer than or further than the focal length of the lens, the distance past the lens at which a beam of light shone into the lens converges on a single point, because once the rays of light cross over each other the ones pointing from above the center have moved below
A phenomenon that I’ve noticed during the 3 eclipses that I have witnessed is leaves on trees acting as pinhole cameras and casting thousands of images of the crescent eclipse on the ground.
Phenomena is usually used to describe something unexplained, but I admit its been used for anything that seems remotely surprising. This would be one of the latter, and yes its magnificent to see in real life.
on a similar note, my family have been using a colander as a sort of many pinhole projector during the last couple eclipses and it makes a cool array of mini suns projected in the shadow =)
I saw a full solar eclypse in Germany like 25 years ago. It was unbelivable how quick the temperatur and environment changed. Temperature dropped massivly from one moment to the next and a strong wind started out of nothing. I can only imagine how scary this had to be for people in former times when they had not idea what caused that.
I saw one in Sweden at the same time, might be the same. The birds stopped to sing here, which was surreal. I can understand that people must have been chocked before we knew what it was
you dont really need solar eclipse for that. On most summer times when it's cloudy it's cold, hot, cold, hot. That's why we always seek for places with shadow when its hot outside.
Back in 1962 or ‘63 I was working as a cowboy in North Dakota. I was herding cattle when an eclipse came through (if that’s the correct term). I wasn’t in the path of the total eclipse. The sky and the ground got darker, as though heavy low clouds had moved in, except there wasn’t a cloud in the sky. The sun was shining, but it seemed to be putting off a lower level metallic light (whatever that might be). I had known we’d have an eclipse so I had brought along a couple pieces of card paper. I punched a hole in one for the lens and used the other as a projector screen. Sure enough the image of the sun was a skinny sliver. I was surprised how bright (even though much diminished) sun in the sky was, yet how little the sliver actually was the sun was round and seemed full. Another odd thing. Birds had been chirping but fell silent and crickets started making cricket clicks, as though it was nightfall. Eerie. Oh and, the cows quit making noise and nervously shuffled around. I had been in the process of moving them to a new pasture and they were waiting for me to drag open a fence so they could be moved. My horse, which was a normally skittish Arabian mare seemed apprehensive but waiting for me to give her directions (which, of course, I did.) she and I had been through a lot together, flooding, heavy hail storms (we found shelter in a big culvert) and we one day found ourselves on the edge of a tornado that passed through. It was chaotic, but we were unscathed. She trusted me. I could always calm her, so I trusted her.
Eclipses are interesting events. It’s incredible how the world completely changes for a few minutes and then ten minutes later it’s like nothing ever happened. Makes you feel small.
Teeeccchhnically, they're just shadows of the clouds. But the light is focused so much that their shapes and even densities are discernable with a good enough lens. You're basically looking at what an undeveloped image on film paper would look like, without the darkroom.
I used to do that all the time as a kid. I'd use a magnifying glass to project an upside-down image of what's outside the window onto a wall of the house. Try this at home, kids.
I have been educated today. But you are actually doing science as it should be done, where the student seeks out the good teachers and learns from them.
You mean without the thought processes and calculations behind it, but just showing the result? Not complaining about cody, but this is infotainment not education.
Cody, if you can still find one, the old projection big-screen TVs had a Fresnel lens (pronounced fre-nel or fray-nel) paired with a lenticular lens to concentrate the light from the projection tubes off the internal mirror into a specific viewing field typically shaped like an oval cone. I have one that I salvaged from one of those old TVs that someone had set out on the curb. There's a CZcamsr that has one mounted in a wooden frame so he can manipulate the angle easily and melts things with the concentrated sunlight. It's an excellent demonstration of the amount of energy that hits a given area of the planet.
I got a massive one of those lenses and while I never got around to building a mount for it, I did melt metal and ceramic using it and just burn stuff.
As happy as I always am to see Cody post, To have a camera (wo)man again is amazing. I hope it is what I think. I'm happy Cody has continued to create after every turmoil.
I like to see that Cody's still making videos, I always learn something new from them, glad that I'm still able to watch your videos whenever you post a new one.
Magnifying lenses are fascinating. Another interesting feature of a magnifying lense is that it can't heat things hotter than the temperature of the source light. Even with an infinite sized lense.
@@AlexTrest because it is just mapping different points in your field of view to a smaller subset of points. Eventually it's just like your whole sky is full of the surface of the sun, in which case it's like you're just above the sun's surface. You will heat up until you radiate energy as fast as you absorb it, which in the extreme case is you completely surrounded by the sun's surface and at the same temperature
In 2017, I noticed a tree having thousands of tiny gaps between the leaves, casting thousands of tiny eclipses on the ground. I'm off to Nazas in April.
I remember, way back in 1999, when there was a total eclipse happened over the southern part of England, I lived a bit further north so only got a partial eclipse, but still quite a significant one, that the light changed where any point of light reflected from the sun formed crescent shapes. Even reflections off glass or other shiny surfaces seemed to take on a curved appearance. The light was also quite subdued due to the lessening of the light available. A very surreal experience.
In the late 90's we had a pretty good eclipse in the UK. The thing that suprised me the most were the shadows cast by trees - the bright spots as the light twinkelled through the wind blown leaves were all cresent shaped, hundreds of litte cresents dancing accross the floor with the breeze. It was a really magical effect and a great day.
There was a partial eclipse when I was in middle school. The science teacher had us go outside and make pinhole viewers. My friend and I, being dorks, poked dozens of holes in our paper to get lots of little crescent sun spots. The shadows of the trees were all curly on the edges, too.
I live in Indianapolis, so I’ll be in the direct path of the total solar eclipse in 2024. When I was a young child I experienced a total solar eclipse, and my dad helped me set up a box for viewing (back then we didn’t have cool eclipse glasses). It’s one of the best memories I have. I’m excited to make some good memories for my niece and nephews.
@@hulking_presence Why do you ask extremely intimate and insensitive questions on the internet? There are a million reasons somebody might have no children. And none of them are of your concern.
Yayyy more Cody, it's so nice to see so many genuine smiles in all your videos again. Never stopped loving the videos but I did miss this kind of excitement and these short lil videos. Love the huge projects but 5 minutes of you nerding out is just as entertaining
Hey, thanks for the video. By the way, I learned about fresnel lenses when I took Drama at school - it's one type of lens they use when lighting plays. The pronunciation we were told, so you know, is fra-NEL, not FREZH-nel.
hey Cody, get some thermal receipt paper to take with you next time you try to burn an image of the sun, also thank you so much for all the vids and experiments you do and share with us :)
HEY! I'M glad you shared because I think I have a great addition. Get the label roll for Brother Thermal transfer label printers. They don't use ANY ink. It's super cheap and it uses heat to make the paper black or red. So just buy a roll of that paper/labels. I'm quite sure it would print the sun very quickly. I'll test with the sun when i get a chance.
An amazing experiment! Well done. Glad to see you're doing well too doing what you want. Seeing your joy doing what you love inspires me to try do the same.
Every time I see Cody upload is a good day :) You made my life so much more interesting all the way back from where you started uploading! Thanks for all these years of teaching us cool stuff!
I've been told that dappled shade is actually many pinhole cameras formed by moving leaves. If this is the case you might see a change during an eclipse, but I've never managed to try it out myself.
this 100% happens, as a kid I remember we happened to be next to a hedge leading up to an eclipse and on the ground behind the bushes were a bunch of small images of the sun on the ground. It would have been sometime around the 1995-1997 timeframe in the U.S. midwest, since i was still in high school at the time and we happened to be out for lunch hour and got to see it. Thanks for reminding me of that memory BTW!
The most recent eclipse that moved over southern California produced this exact effect when the sunlight filtered through the leaves of the sycamore trees across the street. The pavement was covered with countless pinhole images. We could watch the eclipse in progress right on the ground. It's actually only really visible when the leaves are nearly motionless, though, because that's when the apertures between the leaves are stable.
Cody, you should have brought a thermal paper such as those grocery stores use to print receipts on. That maybe would have been more sensitive than wood to the sun's heat. Great ideia, to imortalize an eclipse as a burnt image!
The bit that tripped me up was that the cooler temps from the sun being partly blocked caused those clouds to form. I hadn't even thought of that possibility
I actually kinda doubt that's what's happening. At the very least, there are other factors involved. Transparent mediums such as air don't absorb sunlight as quickly, on account of being transparent. It takes awhile for any change in sunlight to affect air. Sunlight affects the ground faster, because the ground is opaque, but the ground also has a bunch of thermal mass, so it still takes awhile to change. So while the eclipse is definitely affecting temperature, especially at the surface, I doubt it would affect anything as high up as clouds by very much. I could see it being one of the 'straw that broke the camels back' factors in cloud formation, but it would be far from the most prominent factor.
Cody's lab is by far my favorite channel to watch on CZcams. I always get excited when I see that Cody releases a new upload. My favorite thing to watch is his chemistry related videos. A big part of why i've been a Chem major has been due to the fact that I watched his videos when I was younger. Cody is an exceptional scientist and I look forward in watching his future videos.
we had to do a similar experiment in highschool phsyics with a magnifying glass and lamps with glow wires projecting the image.You'd use to lense to project the image of the lamp on the wall. Then mesure the size of the image. Then with the distances from the lens and IIRC the focal point distance of the lense or whatever (can't remember exactly) you could calculate the actual diameter of the wire. That's also how we discovered certain halogen lamps were double winded! The actyual wires were absolutely tiny! Was really cool.
Thank you for also uploading partial successes. This is what science is about and more people need to see that an experiment is allowed to "fail" at the intended outcome. Like in this case it can still produce interesting to look at results that were able to illustrate the principle
Thanks for that Cody! Cool to see the annular eclipse I missed. No experiment is a failure: When an experiment doesn't produce results, it demonstrates what doesn't work, which itself is knowledge. If there were a book of failed experiments I could fill a chapter with what I know is no-go.
Very cool idea and credit for giving it a try, having an idea that depends on an astronomical event and you've got like 15 minutes where you can try before you have to wait months or a year to try again is always anxiety inducing. Darn you, clouds!
Nice experiment. I was actually in Oak City, UT for the eclipse, scheduled a road trip out west around it. We almost went west instead of east but saw the clouds and tried our best to avoid them.
I hope this is what I think it is! And if it is, you found a keeper because anybody that thinks experiments are cool and beautiful is definitely one to keep around.

Nice experiment. I was actually in Oak City, UT for the eclipse, scheduled a road trip out west around it. We almost went west instead of east but saw the clouds and tried our best to avoid them.
I hope this is what I think it is! And if it is, you found a keeper because anybody that thinks experiments are cool and beautiful is definitely one to keep around.
I mean of course it is that way. just makes sense. but I never thought about it. Thanks Cody!
That was great, thanks
I like that you wore your goggles as UV protection! Looks a bit silly but polycarbonate is actually a really good UV Filter.
Love these little details
Wow !, Cody that was cool.
Really cool. Makes perfect sense that it would work this way, but I never thought about it.
for some reason i was half expecting cody to just look at the sun with his bare eyes and tell us it's no big deal
Annular eclipse looks a lot like that black hole pic, so cool.
the ring from the fresnel lens was so cool!
Brilliant experiment concept.
Thank you for beautiful eclipse
Can't wait for the one in a few months. I'm dead center and ready to view!
Haven't watched one of your videos I over a year, but when I saw that notification I instantly clicked
