How to Start a Fire with a Magnifying Glass

- Starting a fire with two different magnifying lenses. For the post on how to make char cloth that I refer to in the video, go here: foodstorageands... If you don't want to use char cloth or don't have any, you can catch different tinder on fire easier than a napkin--newspaper works better, as do some dry grasses/organic material. Char cloth just speeds the process up regardless of the tinder you choose to use and makes getting a fire started a lot more reliable. Cameo appearances by my crazy dog.
I have a 10" focusing lens from a university laser lab. When they upgraded their lab, they auctioned off all their obsolete gear and I got it from a flea market. It is crazy high end. It is highly polished and the convex side is ground to within a few millionths of an inch and I accidentally burnt a hole in a leather boot not paying attention to where I had it aimed. I take it camping and it is used for heating water, starting fires and anything else where heat is needed. When I hit a piece of fatwood it burst into flames in a few seconds. I paid dearly for it, but it is not only super fun, but super handy. Any lens will suffice, but when it's made to focus laser beams, you are at a whole new level
This brought back so many memories back when i was a kid and used to capture flies and burn them with magnifying glass 😂😂
That sounds terrible 😕

The key to lighting paper and not having it just smolder is to compact it and wad it up. Normally that is not what you want to do with tinder, since you typically fluff it out to let the air in. But with paper and other tinders, you need to keep it packed closely together so that when the ray of light burns through it, multiple layers are being lit at the same time. This increases the amount of heat in a concentrated area and allows for the flame to form much more easily.
This is not correct I'm afraid. The key to igniting paper with a magnifying glass is to select paper of a dark colour which will absorb much more of the sun's radiation - including infra red - than white paper, and therefore get hot much more quickly. Even orange or red paper will ignite much faster than white paper. White paper reflects back most of the radiation you're trying to focus on it and is almost impossible to ignite using a magnifying glass. Even newspaper will ignite more easily than white paper if the light is focused on a printed section of the paper. In any case, there is no need at all to compact the paper, just a single sheet will burst into flames on a hot day very easily. I've done this many times as a child.
@@shaunbarnett2972 oh right because it's impossible for two things to be correct. One always always has to be wrong.

Any darker material will work better than the paper towel, the paper towel reflects too much light to take on enough heat to combust/ burn
Nedyarb true
Yeah i used a dry leaf and it worked
Yea!! Ty now I can burn my shcool
Rub some dirt on the paper towel
@@jacobworldwideentertainmen3367 just bring a lighter
Don’t try this at night!

I've done a similar test and like other comments mentioned, the white of the material (I've used paper or paper towels) reflects a lot of the light. I had to char the lighter material for a while using a lens before going back and then setting the darker areas alight. I then tried using just a pen and pencil to draw a line on the paper, and it caught much easier. Next time, just smudge a little dirt on the paper/material if it is light colored and you'll have much better luck.
Great now I'm about to go burn some ants hehehe
not good, Ants never harm you, Except the black ones. You can burn the black ants BUT NOT THE RED.
I have lots of black ants at my home. They don't bite at all. But whenever i'm outside like at the park red ants always bite me...
BURN THE RED ANTS M8!
+The MLG Noob You mean the big red ants???
They're pretty small actually.
Burn butts not ants ;-)
In winter time you can try to make the same kind of magnifying glass from a section of CLEAR ice. For example, you could try to cut a section of lake ice.
If there are "bubbles" or "dirt" in the section of ice that you pick it might not work.
You can also try to use a drop of water on a pair of eyeglasses.
Who knew my skills of burning ants as a kid with a magnifying glass would come in handy!
I've always wanted to do this. Being able to harness the massive amount of energy blasted to earth by the sun! Thanks for this video.
The power of sun in the palm of my hands
I always take small sticks and pound them to pulp with a rock. They ignite really quick. If there are pine trees around grab some of the sticky sap off it and mix it with the pulp. (pine pitch). It will go up like a torch. It so easy to ignite you could probably get it going just by yelling at it.
The reason the white paper towel doesn't work as well is because white reflects heat. Once you char it a bit it works better. That's why the charcloth works better. It is black and absorbs and concentrates heat better. I have had a lot of success in fire starting with a magnifying glass by using darker and finer materials like dryer lint.
The dog wanted to play LOL! Too cute!
Greta video, the doggy makes a perfect addition to it, thanks for posting !
Quarantine week 2 ! And I'm here 😂🙄
Quarantine month 10! And I’m here
Having a traditional magnifying glass with a good handle makes it much easier; being able to hold the dot steady means heat builds faster than when it's dancing around.
Funny I came across this. Just the other day I lit my friend's cigarette for him with a 4" lens without him even dragging on it, lol!
A couple suggestions to make lighting fires this way easier (from a physicist):
1. White reflects a lot of light, but black/dark materials absorb much more of it. That's why the black stuff you used helped so much.
2. If possible (which it usually isn't in survival scenarios), angle the surface you're trying to burn so that the sun's light hit's it perpendicularly. The sun's usually at an angle, so if you focus it on flat ground, the image is spread out a bit more.
3. Get a 1000 mW blue laser. They light everything on fire within 3 feet. AND they work in the rain/night. lol!
I tried to do this to fry an egg after realizing it wasn’t hot enough outside, but it didn’t work. What did I do wrong?
I wonder if any accidental fires have started bc of the sun doing this to random objects that can magnify
I started a fire using a magnifying glass with mulch at school
And did you burn the school down?
+Bryan Gaytan no
+Jorgan Morgan™ sadly
Jorgan Morgan™ lol I saw u doing it!
i wish you burnt the school down even if it was not my school
Good idea to have a few in your survival pack.
Using dry grass or dry leaves ignites faster than paper. I started fires 🔥 like this as a kid in the Boy Scouts.
Should u look at the spot that's doing the burning because my i feel blind after I keep looking at it lol
•Limitless • wear sunglasses while looking at the dot
i try not to look at the dot.
it's pretty much like looking at the sun.
so...
LucidDr3amzz, if you can make a holder for the magnifying glass so that the glass itself doesn't move 1 millimeter than no you shouldn't. Once you get the beam of light going just make sure the glass doesn't move and you can walk away from the situation completely about 5 - 15 feet.
It is dangerous for your eyes so make sure not to look at it too much
Used to start a fire using dry leaves & a regular magnifying glass as a kid.It took awhile. Recently showed my grandsons how to do this & it literally took less than 10 seconds! Something has definitely changed with our sun
When you were a kid you probably did it when the uv was lower maybe you were in a different area or doing it late in the afternoon or in winter if you do it in australia in summer in the middle of the day it takes 5 seconds
I also used to play around with dry leaves and a magnifying glass a lot when I was a kid. I don't remember being able to create flames though.
can you use glasses
Only the long-sighted ones
@hann5640 hann5640 smart
I think you could actually
Nice job… windy day was the trick and you still got it going
1:50 that is because the paper is super bright and white, so it will reflect off all the light and heat. But a black paper will absorb all the light and heat, so it will catch on fire quickly
white people dont get tanned easily, we get it
@@rexyaxy4314thats biochemistry.
My friends did this at school with his glasses. We could smell smoke. It was fun.
This is why I’m a pyromaniac
I hate to sound rude but the reason the paper towel wouldn't light was what you said and it is white so it will reflect the light more effiently than black
where do you get magnifying glass without handle?
It would be cool to build a little contraption that would let you set the magnifying glass on it and you can crank it up or down, so you don’t have to hold the magnifying glass while you’re waiting for the fire to start. Probably a lot easier too because it would make it steadier.
You should make one and post it so we can see what it looks like . its a good idea .
@@lizchatfield692 lol touche
I love your video. I wanted to know the angle of the light and how it works and I don't have a magnifying glass to play around with. I am broke, do you know where I can get a free magnifying glass?
You may be able to get the fresnel lens type of magnifyer at your local pharmacy. Some have them available for free to help those with vision problems be able to read their medication bottles. Other than that, not sure where you'd get one for free.
Food Storage and Survival
Thank you.

Hi i was wondering what Magnification is these mirrors? Would it be 3X , 5X.. 9X..?? ty Great DEMO
Seriously. Nobody seems to mention this. I bought 10x (Amazon/China) but couldn't start a cotton ball (easiest tinder I've found)
@@antidulvian666 I started a cotton ball with ease with my 3x.

lint from a dryer works even better
I remember this as a kid, decades ago.
*magnifying glass tilted right*
Was anyone else caught off guard that a woman made this video? Not because she can’t or shouldn’t. But because she’s bold enough to do something people wouldn’t expect. Much respect?
Its just nice seeing some women out there that arent superficial. I wish I could find a girl like her. Shes one in a million. You have to look very hard with a magnifying glass lmao
The focal point of the magnifying is at work.
White materials do not work as the reflect the light. Char cloth does not burn it forms a coal in the car. Fresnel lens don't work.
This video was produced by the dinosaurs
Would it work if you try it on sticks?
It seemed to me she didn't make the circle of light as small when using just the paper towel.
when the world is ending, we will all come to this girl for surviving🗿
Thanks a lot. Love from Bangladesh
I already did it without this video but i searched on google how to amplify the effect of a magnifying glass and i found this.... and i made fire with only a magnifying glass ,dry leaves and dried long grass(the magnifying glass was much smaller than the one in this video)
When you said food storage and survival, I think of your dog. Is it your food storage in some extreme condition? LOL
That doggo though 😂☺
Man if that grass was thicker and still dry you would’ve had a brushfire on your hands
Reminds me of a story I read in the news some years back. There was a psychic whose house burned down because his crystal ball focused the sunlight onto his laundry. Looks like he would have seen that coming.
Badd dumm tsss
I also try it with my lens but I wait for half an hour but it didn't work 😢😭😐 I use writing paper but not tissue paper , is that OK 🙏
Can a magnifying glass of 5 times zoom start a fire I want to buy a magnifying glass necklace and I was wondering if a five times zoom lens would have the power to start a fire.
Just put another piece of paper towel of the smoking paper towel loose enough to blow on and it will catch fire (if you don't have charcoal thread things)
Come on mom play with me!! Good vid and loved your pup videobombing!
nice ... if you take a concave reflector for starting fires... u can make a spotlight/ flashlight from fire sources (lighter/ matches/ torch works too about 30 feet away) ( solar lights sort of works with phones
and is good for seeing your face in ...
Bigger = easier to focus light even with partly sunny skies..
Tinder that's dark well start burning faster...
that dog scared the ** out of me lol
me and my friend started a campfire with a dollar store magnifying glass and a dead leaf
I will find this vary handy🕯🔍🔎💣
Make sure the light isn't as small as it can because that will obliterate your stuff you want it to big a little bigger so it can smolder
I light my bowl of weed with a magnifying glass.. whole new meanig to "going green". Freah af!
Me and the boys pretending to be cavemen.
Someone on my class did this in chemistry. The teacher didn't notice them but they got a stick and put the a magnifying(cause we were looking into flowers) and put it in the sun.
you should magnify it on a black post of the paper, use a pen to make parts black
i just found a sigaret box with few.. ...in it and pointed a magnifying glass dot on it, it started smoking and i put a paper towel on top of it and poured olive oil on it and it immediately started flaming
easier to carry a box of matches or a lighter than carry a char cloth
This is how chunks of us died
I have a magnifier but I us it on a stick or a old pace of wood in a house then I tun it in to a torch it takes me 20 to 90 seconds to set it on fire
Finally my order came in 😂
You could it’ll take a long time
*i searched badboyhalo and this what came up*
If you don’t know who that is it’s a famous youtuber who get annoyed when people donate magnified glass and ye lol
COME HERE BAD!
I love ur videos

my SIS's did this to my arm by accident I screamed
My grandmas sister did this to ants all the time with his moms sewing magnifying glass. even once he was curius wether it would work on a cat so he had this cat that would live around his house and it was sitting in his lap so he pulled out his trust magnifying glass and burned the paw slightly and the cat ran away after biting him and the cat hate him since although the cat is most likely dead Rip Cat

I thought using magnifying glass alone was enough. I'm watching Keep Breathing on Netflix right now and the main character can make fire with wearable glasses (probably for shortsighted) and paper money.
i like da dog
You can also use cattails as tinder
And people think that lasers don’t exist?
