Today, getting what you need is as easy as a trip to the store. From food to clothing, energy, medicine, and so much more, Andy George will discover what it takes to make everything from scratch. His mission is to understand the complex processes of manufacturing that is often taken for granted and do it all himself. Each week he’s traveling the world to bypass the modern supply chain in order to harvest raw materials straight from the source. Along the way, he’s answering the questions you never thought to ask.

man, why the HELL did anyone tell you that is a BAD IDEA to DRILL GLASS with diamond BLADES with your bare hands? When I saw the first second of this drilling I knew its going to end bad.
Hey man, it's a Minnesota thing. We know it's dangerous but we still do it because we don't feel like finding our gloves.
Source: My dad almost cut off his thumb (again) with a table saw a few days ago
bagunzi could have been so much worse too
OSHA needs to start auditing people like this in their homes
Same dude
mr Overcarefull was found. Mission Successfully completed
Andy: Unfortunately, I still haven't quite figured out level 1. What should I do?
Louis: Definitely move on to level 170.
Sometimes you have to run before you can walk. Or drill before learning how to operate a drill safely
He figured it out now
Safety was not number one priority in this video
Boom look at that
bhai rankar look at dat
Boom!
When he cut his finger: Uhouh!
bhai rankar you forgot da "the"
glass manufacturing = the bane of How To Make Everything
Wrong. Just ask the right people to help you, namely amateur telescope makers.
amateur telescope makers don't typically make their own glass. They'll either start with a premade lens, or with a glass blank.
glass blowing
True, but I know some of them on CloudyNights have made their own glass, just for the heck of it.
But it’s
So
Damn
Pretty
I'm glad you got a sponsor! More money for you = more content from you!
Holy crap it's been a long ass time since I've seen you.
byalexandr I spend most of my time on the PCPartPicker forums, now.
TheJTguy Years ago from the LinusTechTips forums.
byalexandr Indeed. Great to see you again.

Drill with a diamond-tipped drill bit, use your bare hands to touch the glass it is cutting.. what could possibly go wrong? :))
I was actually expecting you to get hurt when I saw it, and it happened.
be careful
& after he got cut he still did the glass
Please, do how to make leather gloves. These would help lots, not only for us, but you too.
He'd have to raise a cow for that
Dan Witzke or buy premade leather
Catch a deer.
Skin it.
Tan the hide.
THEN make the gloves.
@@cleverusername9369 😂🤣
Just found this channel.
Two hours later, and now I'm hooked.
Love your content, keep it up man!
same lol
same bro

LinkTheCoward sameee
I`m afraind i will end up the same :D
Me: oh man he's gonna slice his... yep there it is
Every time he fails feels so sincere
baylego it honestly is the number one thing that keeps me watching his content and not other people's content
I would have completely abandoned the whole project if even the easiest step failed at my first attempt. These have some real patience
3:41 Who else saw that coming...
Pretty much everyone.

Coming soon: "How to make a RUclips video from scratch", including a camera, microphone, computer and *the internet* made from scratch!
u could make an "internet" by connecting multiple PCs together :D which is basically internet, but not
Its a network so it technically is internet
I am sure the Internet (as in anything past your router) can be considered a "natural resource" like flowing water and electricity today. But I guess he could start at the camera and then work his way backwards.

Instead of making an optical telescope like this, you could have had a much easier time making a reflector. Because you don't need lenses at all, just mirrors, which are MUCH easier to make and make sure they're clean and pure on the surface. I highly recommend a Newtonian design, as they are the simplest. (though a Cassegrain or Gregorian could be a nice challenge)
But (glass issues aside) your optical telescope could be improved by making your lenses thinner. Thick lenses don't quite follow the thin lens equations I presume you used to calculate focal lengths.
Focal lengths calculation could also be vastly improved by using a stand/clamp of some sort instead of just holding the lens, which leads to pretty inaccurate results.
Good points, thanks!
A reflecting telescope is definitely on my future agenda. The most difficult chemical I need to source for the camera film is likely silver. So if I get access to that later this year, I can also use it to make a mirror and attempt a reflecting telescope.
The primary mirror is very accurately ground concave mirror
Further, he doesn't necessarily need to use glass when making a reflector. He might could use a rock with fine grain and coefficient of expansion close to glass. Even then, if he wanted to he could use obsidian i.e. volcanic glass and make a reflector from that.
It made me cringe when you cut yourself. That looks like it really hurt
this is one of the best channels on you tube its seriously under subscribed
Kids, always wear safety gears when you are using tools
That only does so much...
SEIFTI IZ NAMBER WAN PRIOWRITY
kakuella safety number on priority
He has to make them first
You probably are a kid.
This video and your glasses video helped me appreciate why my high school history class made such a big deal out of Galileo making his own lenses. In high school it was like "oh he did his own science experiment. Seeing this I was like "Oh, he wouldn't have been able to make his discoveries without also being very skilled in glass making techniques."
that cut looked painful AF
A selfie from scratch wouldn be really interesting.
I hope the next glass turns out great ^_^
CreeperGreenMC too fucking difficult
mariano pesa I think the optics will be the hardest thing but i think a primitive camera does not need tremendously much.
CreeperGreenMC something like a pinhole camera could be fairly doable I believe
emilclaudell Yeah, but Lewis said that Andy should use his knowledge in optics to make one. So probably something a bit more advanced
CreeperGreenMC yeah, just watched the video till the end, sorry about that
Never clicked on a video so fast before.
Like 4 times this dude was told to leave the glass in the kiln for longer, yet he STILL leaves it in for like 10 or 5 hours
There is a ton of channels on youtube sponsored by the Grand Courses but I think yours is the most related in content than any other because you are always trying to learn new skills and then you teach us what they are about and maybe inspire young minds with your awesome content.
Love your channel, keep it up. ;)
*is using diamond cutter*
Me: he’s going to cut his finger
Him: *cuts finger*
Me: welp.
He was damn lucky it wasn't worse.
I had a shiver go up my spine seeing that accident. I'm not squeamish, just really empathetic. Half felt that cut.
these videos are nothing less than stunning. Thank you so much for making them.
DUDE A SPONSORSHIP!!! IM SO PROUD OF YOU DUDE! START A FREAKING PATREON AND A PAYPAL! People love your shit (like me) and we ALL want you to succeed at this!!!
2:15 that is brighter than my future
this makes you appreciate the work people put into making stuff that works
Great courses plus sponsored wendover and real life lore I think so thank you for supporting my favourite channels great courses
Subbed, videos are definitely interesting. Why do you only have 220k, you should have way more, the production and editing is great aswell.
I appreciated that you used recycled glass. Good for the environment, and gives you clearer glass
Please do not ever hurt yourself like that. You don't deserve that. You work so hard to create these things, not just so you can get a deep cut. I am glad you didn't hurt yourself insanely.
I've been wanting a telescope for the longest
I hope your finger heals up quick, that looked really painful!
FYI broken bits of glass are often thrown into a new batch of glass.
Found my way over from king of random and Cody's Lab. Love the collaboration!!
Yes, finally!
Telescope!
Lol I was first
make a watch
Can't wait for you to nail the glass! It'd then be cool to see you go back and replace the glass for all the other projects!
This guy is the best example of doing everything the wrong way, just to do the right way in the end.
Thanks for the video. Very cool. Love how you stay true to making things from scratch. Question: do you have to use glass or can I mill clear acrylic to the right arc and get passible results? Again, love your enthusiasm and projects. Thanks so much.
depends on whether the refractive index of the acrylic chunk is similar to glass
Next up on How to Make Everything: A Child
Ohoo
Maybe "how to make an accidend"... sorry, I mean "you"
Really easy.
For some, too easy.
One time my 7th grade Life Science teacher at Hale (Dr. Gros) assigned a class project to either make a microscope, telescope or periscope. Microscopes got the highest points followed by a telescope and lastly the periscope.
Whether it worked or not, that telescope is a beautiful piece of rustic woodwork, nice work
I expected that finger cut
Can you make liquorice from scratch?
this bloke sacrifices everything for education. deserves more subs
YES!!! I asked to make a telescope in the Eyeglasses vid!
9:15 You should go try growing a garden :D
You are an extremely creative and smart man. I admire how you can pull off these proyects.
This guy lives life on the edge
Makes you really think about the great inventions of history, and how long it took to craft the first versions of them.
speaker and tube amplifier from scratch ?
good job. You spent a long time working on this. you deserve more subd
I’m so emotionally weak. After watching him make stuff for hours of video content on the channel, I’m falling in love.
So excited for this camera idea
Next video: how to make a new finger
Galileo approves
I love that you put Lewis' ideas into practive. I absolutely enjoyed his book.
the camera idea sounds amazing
Why did you not make the wood glue from scratch??? Good video though
I made animal hide glue before: ruclips.net/video/38v7AVTZpMw/видео.html
Which was frequently used as a wood glue. I didn't use it for this project though, because I ended up having a tight deadline and didn't want to risk losing a day because my glue didn't hold. I might do a series on making adhesives in the future though, since they'd be a useful supply to have. Making my own duct tape from scratch could be interesting.
How To Make Everything ok keep making good content
wow only 200 views
Your approach is clearly, the journey is the reward.
After watching about 20 of these videos, I really want Andy to be able to make clear glass!
Don't give up!
ouch
I hate light pollution.
As soon as I saw you holding the glass part while cutting it 😮
“That’s not a good ide . . . Oh !”
You're basically on the same journey that I'm on, but you started earlier - your content is bizarrely perfect for someone like me.
Make a hat 🎩
It might be easier to make a telescope with mirrors.
Yeah actually I do, do you? You might want to google it...
Adam Hill lol get his ass
He deleted the comment lol.
Once I get access to a source of a material to make a mirror, I'll definitely be making a reflecting telescope.
CURVED mirrors !
Put extra fine steel wool in vinegar, wait till it's completely dissolved. Great woodstain on the cheap.
Love the video. I'm just getting into glasswork and telescopes over the last few weeks, so perfect timing.
man, sorry you got hacked
Rip he got hacked
I dont know why, but your videos help me make my physicsexercises when i just listen to them on headphones, thank you and amazing amount of crativity you come up with
So far the most satisfying and interesting RUclips channel, keep up with the great work!
Try to make a refracting telescope, YOU CAN DO IT!
This is a refracting telescope, you mean a reflecting telescope?
Grind glass with your bare hand? Why doesn't it shatter ?
KEEP DOING THIS!!! This series is bloody great content man!
dude!! The slo-mo shots are awesome!!
booo. you should make a video completely dedicated to *successfully* making clear glass to get my boo revoked.
TheBlapman He's already said he's going to.
Can't wait for the selfie episode!
I'm just wondering, and this might sound stupid but could you take out the air bubbles from the glass by using a vacuum chamber using the same material as the crucible and make the lid transparent, this way you could put in the boiling hot crucible with molten glass into the vacuum chamber and take out the bubbles, granted the glass may solidify before taking out any good amount of air bubbles. just a thought.
When he cut the molten glass, So satisfying
That cut was pretty gnarly. It could have been much worse though.
What I really love about this channel is you are not good at any of the skills (no offense) I mean you are pretty bad at everything BUT you are doing them and making something! That is incredible. You are showing everyone that you don't have to be great to make something cool.
You would be immensely more succesful in making your own lenses, if you used the methods amateur telescope makers have been using for centuries. Go to CloudyNights forums and ask away. The knowledge there about telescope making is immense. Yes, there are people there who make their own glass (for mirrors, anyway) and people who grind lenses. There are tons of books on the subject as well. Jean Texereau's "How to make a Telescope" comes to mind.
YES make a camera, film and everything!!!
I should tell you that the invention of leaded glass was a huge leap forward in making optical quality glass for usage in telescopes. You can't drink out of it, but it's like a cheat code for clearer glass.
I really enjoyed the longer format of this video.
I have a walnut tree in my backyard and extract the pigment from the fermented hulls similar to how you do for the dye except I concentrate mine down and use it as pen ink for my fountain pen.
The only youtube tutorial channel where I don't skip the process and ouch thats painful.
This dude works so hard... props
I like how Louis is like his sensei, always setting a new goal haha
My teacher shows us his videos all the time lmao i love this channel
You are probably my favorite youtuber
During the annealing process of glass, your forth was one with the the "slag" lol. Interesting how its at the end, rather on top as in most metals where it can be on top of the molten metal than generally is removed.
really awesome video as always, it really saddens me that glass making is still an issue but at the same time make me appreciate something that i take for granted. keep up the awesome job, hope you finally nail glass making in upcoming videos.
I'm strangely so invested in this glass project LOL
1:23 walks in with a torch firing on his hand
- you sure this actually works?
- you blind?
XD
We'd love to have you try to make beer again at Excelsior Brewery.
