In this video I took your suggestions to magnify the world's brightest flashlight with a giant solar scorcher magnifying glass! In my video about the blackest black vs the world's brightest flashlight I got so many requests to magnify the flashlight that I knew I had to do a video on it.

Hi everyone! I like all of your ideas on how to magnify the light! But the truth is that thermodynamically you cannot magnify a light beam to be brighter than its source, no matter what method you use. This even means that there is no method of magnification that could magnify the sunlight to be hotter than or brighter than the surface of the sun.

@larryscott3982 6 лет назад

The Action Lab The goal isn’t magnification, focused concentration. I’m thinking 2 complimentary Lens, and concentrate the 6” source to a pinpoint.

@chriswilson1853 6 лет назад

Larry Scott You can't do that because it's impossible to focus light to a pinpoint. All you can do is create a tiny image of the original light source.

@Steelgeek 6 лет назад

Stupid first law of thermodynamics, ruining all our fun

@TheActionLab 6 лет назад

Here is a perfect explanation of why it isn’t possible-what-if.xkcd.com/145/

@Cruz474 6 лет назад

I can put my laser through a lens to make it converge into a focal point, and it burns ALOT better at that focal point than it does without the lense. I think you need to try again.

@johntheux9238 6 лет назад

It won't make any difference between vanta black and a low cost black paint

@SreenikethanI 6 лет назад

*John theux* there must be atleast some difference because vantablack absorbs 99 point something % of all the light and regular black paint reflects a lot compared to this So maybe that vantablack will heat up faster

@johntheux9238 6 лет назад

Yes but like 4% faster, not a real difference.

How effective of a visual night-stealth suit is it when you apply Black 2.0 on a full body suit? 3. How dangerous of a laser gun can you turn that flashlight into? 4. How do animals react to objects that are covered in Black 2.0? 5. When you apply Black 2.0 on your clothes, how many 80's goths appear from the alleys and caverns?

@jaxter6610 6 лет назад

Move the light itself closer to the wall, and have the magnifying glass directly in Front of the light

@mrmilkshake9824 6 лет назад

Jaxter my thoughts exactly

@peterzingler6221 6 лет назад

Nope will Not Work a magnefier has Like a x beam you will Just Spray the light even more you need to Hit the middle of the x

@2243555 6 лет назад

Wont work cuz according to physics it will make light even more spread

@jaxter6610 6 лет назад

Sajitha SurAnJAna. How so? From my knowledge, position the magnifying glass in front of the light would focus it at one point, but passed that point it would be spread out. So if you placed the light itself closer to the wall then the focal point should taking up most if not all of the light

@2243555 6 лет назад

the thing is if u put the flashlight right in front of the lense then the length between the light projector (the flashlight) and the lense would be lower than the focal length of the lense. Thus creating the image of the flashlight in what we call the infinity.

Mr. Piebro im just saying why is everyone hating on youtubers for making there vids 10 min when this is how they make a living

@mr.piebro9010 6 лет назад

Declan Mercer Like I said, there's nothing inherently wrong with it. But if it's sacrificing the quality of the video, that means the creator prioritizes income over quality. That's when in becomes unwanted.

@kakashihiddenbapevillage6259 6 лет назад

Mr. Piebro "income over quality" so you cant make a quality video just because its 10mins?...and im sure "quality" isnt going to pay bills smh. youll understand when you have to pay all of your own bills, hes probably getting money from patreon supporters which is why he doesnt have ads.

@BadAssMorgan 6 лет назад

Why did you never move the flashlight closer to the wall. The magnify glass has 2 focal points. You only focus between the glass and the wall and left the 32000 flashlight way out of focus.

@TheActionLab 6 лет назад

I showed you both focal points, both were in focus

@kendallhardy2753 6 лет назад

I was thinking the same thing, why not move the flashlight closer and try it? Tested with my super week led flashlight quickly and it didn't work. There was a point where the flashlight was too close and my lens could not focus the light at all so I had to back it up. There is a minimal distance the source needs to be in order to allow the lens to focus. But what I did find was that the further away I put the source the smaller the focussed image I could create, but also the dimmer it became.

@ethanm3923 6 лет назад

The Action Lab I see that you put the magnifying glass closer to the flashlight, but what if you moved the magnifying glass and the flashlight closer to the wall? Would there be a small dot on the wall then? Like: flashlight -a few inches- magnifying glass -a few inches- wall?

@akuljamwal3085 6 лет назад

I was wondering the same

@jasonbourne485 6 лет назад

You should have put the flashlight at a distance from the magnifying glass so that the entire beam of light enters the magnifying glass while the magnifying glass is 1 focal length away from the wall, this would focus the light to a point smaller than 1mm, this way you could reach a much higher heat at the cost of lower area, totally worth it.

@hi_its_jerry 6 лет назад

Surya exactly what i thought

@Bob5mith 6 лет назад

Magnifying glasses are convex lenses. A concave lense would only spread the light. Convex lenses concentrate or spread the light depending on where in relation to the focal point you measure. www.synopsys.com/optical-solutions/learn/optics-for-kids/lenses.html He could concentrate the light to a very small point with the right convex lense, or combination of lenses.

@EpicLPer 6 лет назад

Here's a question: Can fish live in distilled and/or carbonized water?

@dan428 6 лет назад

EpicLPer I would say depends on the fish but most likely no, fish are very sensitive to pH levels. Both distilled and carbonized water have low pH (acidic), and also low absorbed oxygen content. They would suffocate.

@mrbenjiboy9527 6 лет назад

@dr.aparnanainar327 6 лет назад

They would die of endosmosis,in short they would burst

@TSPxEclipse 6 лет назад

No. There has to be oxygen diffused in the water. I mean, technically you could with distilled water, but first you would have to shake it vigorously to introduce enough oxygen.

I wish you tried sticking a magnifying glass, with another magnifying glass in front of it. Try two small, 1 big, 1 small, 2 bigs, etc. Then try like 10, create some kind of rig, with the magnifying glass held up in position, and put 10 all lined up, and space and change for optimal layout.

@hqcart1 6 лет назад

hi, i am unsure if the burning paper came from the heat generated or just the light... when you had it so close, the LED lights themselves can reach 90C! can you keep the paper 2 inches away and try to get it to burn?

@thesentientneuron6550 6 лет назад

90C is nowhere near enough to even decompose paper, let alone catching it on fire. In some nuclear tests, support cables made of steel were coated in black paint while some others were wrapped in foil. What they found was the ones coated in black vaporized immediately and formed spike in the nuclear fireball. The ones coated in foil were completely unscathed. Hence, they showed that the light was the one inducing heating, not the 'fireball' itself. Edit: You can find this on Wikipedia, though I don't know what it's called, so I can't give you a link, so if you find it, then good for you.

@thesentientneuron6550 6 лет назад

At 2 inches he could use an ultra short focal length lens to magnify the light, although those are REALLY expensive. On its own, at two inches, it wouldn't heat to decomposition temperatures.

@funzosupport6922 6 лет назад

The ignition temperature of paper is 451 degrees Fahrenheit, or 233 degrees Celsius.

With a high emmision lasers all you will do is either melt your lens, or at least only dim the output. True lasers will not significantly expand for a significant distance, and much of that will be from diffusion in the medium the light is traveling.

If you want to converge the rays you first have to have them come from infinite onto your lens. Best way to do it would be to use two lenses, one to set all the rays parallel to each other and second to converge them, this would be really efficient. Sorry for any error, I'm tired and English isn't my first language.

What will happen if you put a lot of magnifying glass in front of the flashlight?

@TheActionLab 6 лет назад

less and less light:)

nah it just gets dispersed because of all the glass planes it has to go thru

Also, there is no more light, and therefor heat, going to the target. The light defuses because of the extra lenses, so you are getting less light through to the point. The king of random (Well, Nate) did a video about this a short time ago.

The large image was only possible because of the distance between the flashlight and the wall. There is a specific distance for the flashlight to be away from the wall where the magnifying glass will focus to a point, or at least to a very tiny (and hot) image. Actually, leave the magnifying glass at the point where you get a focused image and move the flashlight closer to it. Make minor adjustments in the location of the lens while you move the flashlight closer.

@RayPossibleGT 6 лет назад

Wouldn't it react with acid normally?

@ritesha8050 6 лет назад

Nope bro it would explode right in your face.

@tennicktenstyl 6 лет назад

RayPosSiable nah sodium is a very subtle element.

@ritesha8050 6 лет назад

If it explodes in water what will it do in a strong acid.

Whenever a burglar comes. Glue the normal magnifying glass lens the the flash light, then put it in front, then hook it up to a pressure plate in your yard :)
