I'd kill and die for my dad so don't get me wrong... but am I the only one who's like raging jealous sometimes of his son for having a dad as crazy smart/cool as he is?! Probably just me.
All University Professors should watch this guy to learn how to teach. I have ADHD and have learned so much so fast from his videos because he explains things so clearly.
I laughed when it happened. He's so obvious it would have been more stealthy if he simply walked past normally :p that way it wouldn't even have registered with me
Great to see you here! Try it out but instead of using a vacuum try heating up the DCM and allowing the vapors to displace the air in the ampule. I’d imagine that as soon as you seal the ampule and allow for the DCM to condense you’d achieve similar results to drawing a vacuum considering that the highest vacuum you could pull would be the vapor pressure of the DCM. Love you videos and would love to see your take on this video an maybe shout Tech Ingredients out as he’s a smaller channel with a more niche audience! Best regards, Al
@@-a13x-75 I'd thought about doing this just with water years ago when I was on a torch more often. The issue with doing it with water is that steam is an *excellent* conductor of heat compared to air. Filling the glass with steam makes it far too hot to touch without tools. It's doable, but it becomes more complicated. I've no idea if it would be different with DCM.
The spit is analogous to cutting panes of glass with scissors, underwater. The water ameliorates the vibrations that allows cracks to propagate. Water is also used in engraving glass for the same reason, with the bonus of keeping the glass cool. The next time that you need to cut a hole in glass, place it in water and use a hole saw with a CORDLESS drill (no mains cords) and the central pilot drill removed. Caution, will not work on "safety glass",
According to Scientific American: "Water causes the glass to crack more easily because when a water molecule enters the crack, a reaction occurs in which a silicon-oxygen bond at the crack and an oxygen-hydrogen bond in the water are cleaved, creating two hydroxyl groups attached to the silicon. As a result, the length of the crack grows by the size of one bond rupture. The water reaction reduces the energy necessary to break bonds, thus the crack grows faster."
@@jimmyb1451 Ah yes... all part of the glass/ceramics' world of 'crack energy propagation' and the materials engineer I worked with had the math for it as well.
Thanks for the info BoscoBob. Very good to know. I use diamond hole saws quit a bit, and I used to make stained glass lamps and windows and never knew these things.
Just like you, when I was a kid I was fascinated by those old Noma bubble lights. Later in life I was just as taken by watching how the old WurliTzer bubbler jukeboxes used the same tubes, only these were heated by actual immersion elements. Naturally I found this video delightful. I am always pleased to see someone who has never lost that sense of childlike wonder, but has rather developed a rigid discipline of practical physics and applied sciences around it. At the risk of sounding cheeseball, don't we all form a hard shell of borosilicate principles, so we can nurture that colorful wellspring of creativity within? I don't know if you ascribe much to old Abe Maslow's hierarchy of needs, but you're probably one of the very few self-actualized people I've ever seen, let alone met. Bubble on, MP!!!
You guys are such geeks. And I mean that in the most positive, complementary way possible. I love your channel and I love how you approach things. As a basement scientist, your videos always make me want to raise my game. Thanks.
for a living im a black smith and ornamental fabricator , some of my job is work that's been done by humans for several thousand years but at home I'm a tech tinkerrer and inventor your videos' offer so much practical education in such a consumable way thank you
When I took neon sign making classes in college, they taught us to score the tubing all the way around with a file, then place the file under the tube with the score right on the edge of the file and push down on the end of the tubing on the opposite side of the score from the file. This worked very well and didn't require that you get your thumbs right next to the cut. That being said, I still have a scar on my thumb from that class, so perhaps your method is superior. We were also using leaded soda lime glass not borosilicate glass. The other lesson I still remember from that class that's relevant here is that glass that's just below the temperature required for it to be soft is the exact same color as cool glass, so you have to be really careful not to grab a recently molten piece of glass and burn the heck out of yourself. This is a super cool project! I really hope I win the patreon lottery!
@@richardbarrow2977 - but it never does "break incorrectly". It snaps at the score (weak) point, which is precisely why you do it. Same as cutting a flat sheet of glass, you score and snap.
@@darkfur18 - there was nothing mentioned that the breaking of glass tubes caused the thumb injury. I will quote: _"This worked very well and didn't require that you get your thumbs right next to the cut."_ .
Great video. Great science. I remember having Christmas tree lamps like these in Kitwe, Zambia when I was four years old … around 1962. I’m certainly going to make a few for my bar … a real talking point.
I cannot tell you how much I enjoy your RU-vids. Liquor making, sailboat building, rocket engine production, and booms and blasts and explosions of all sorts, and now, Christmas decorations and ornaments. As said in a comment before me, you are RU-vid’s Mr. Wizard. And the pièce de résistance : My daughter is a grad student in analytic and organic chemistry and I will make one of these with the dye and see if she can answer. She teaches me a lot, it will be fun to explain this to her. Merry Christmas to you, Mr. Wizard, your crew and your family! Best Wishes for a wonderful 2022!
u guys might just be the greatest wealth of knowledge on youtube. you are one of the very few that is without bias and obviously accurate. really there should be no reason government employees elected or otherwise could not provide their data in simmilar fashion, unless they dont want it repeatable.
I'm constantly impressed by the information density in these presentations. I find myself having to pause every now and then to really take everything in, because there are so many little interesting comments interspersed with the main topic. I consider this to be a massive positive - anything that makes me actually pause the video to think about it is very engaging. Bravo, friends.
This was fun to watch but it's hilarious to think that a bunch of people just have full blown labs in their house or garage. I would love to do this but it's pretty involved.
Nothing exploded... still, one of, if not the best video ever! I wonder how many people on the planet want to "grow up" to be like you...? Excellent team, content, coach/Head Mad Scientist, and channel. Many happy, preplanned explosions to you, and an especially crazy new year, buckle up, Canada!
This is by far one of the best practical science channels on youtube. The clear, concise, and organized presentation makes it so easy to follow. Very impressive work and a big thanks!
You guys never fail to make a 40 (+) minute video about a topic that doesn't really interest me, utterly fascinated. I can't wait to see what you guys have planned for that milking pail setup (~27 minute timestamp).
@@TechIngredients I'm still (no pun intended) going through your back catalog. I think that's coming up soon. I wish distilling was legal here, that banana spirit looked tasty. Thanks for sharing your knowledge through making these videos. They are educational in an incredibly practical way. Tons of homeschooling material when the kiddos get a little older. This channel is a gem.
Thank you for this video. I look forward to making this with my daughter when she starts doing science projects as I do with all of your videos. You give a dad a lot of idea's to help engage, teach, and learn with my child to better us both together. Thank you again!
This is cool! I have loved bubble lights for my whole life being a huge part of Christmas of my childhood, they always went on our tree each year. This could be a good solution to old bubble lights with burned out lamps, changing them to LED. Or with broken tubes, to create new ones as replacements. At the very end, the tubes you demonstrated with water added, are very similar to an old style of tube made by NOMA called the 'Shooting Star', which had a small amount of oil and had a similar lava lamp effect. Very good work! 👍
Merry Christmas and thank you for the trip down memory lane to a bygone era. I loved seeing these type of lights every Christmas Eve at my Aunt's house. They were mesmerizing to a young boy, and still are today so many years later.
Very good tutorial , thank you . As I was watching this video on my tablet I was struck by how FAR we have come technically. If I think back to the magic of colour TV and here I am enjoying amazing technicolor clarity on a thin lightweight 7 inch device . What a giant step in such a brief time !
The man sneaking through the scene around 5:20 trying go be unnoticed, made himself stand out so much more than if he just came down the stairs and walked by.
We laughed about that, but needed that footage and we were stuck with using it. He had expected that the camera on the stairs would be the primary viewpoint.
15:47 Take a still image against a black piece of construction paper. And just drop the image in. Keep the hand moving toward the camera, that is still useful. 😉🥂
How fun! I was just explaining these lights in detail the other day. A friend saw them at the local hardware store and asked how they worked... so I broke out the DCM and a test tube and showed him!
Tech ingredients! I think this may be the first time I know something you don’t know. Sound travels much more quickly in water, so natural processes oftentimes will happen differently. Glass fractures happen much much more quickly in water and therefore they often take the shortest path under water. Try taking a pair of scissors to a 1 to 3mm thick pane of glass with it submerged under water. It’s amazing the control of the cut you have with it under the water. This is also why - apart from convenient bulk removal - I think wet-saws are so proficient at making cuts that are clean and without run-away fractures. Whether or not this aspect was deliberate or just a pleasant surprise is yet to be determined. To get more technical though. I believe it is the mechanical damping the glass gets while under water that keeps the fracture vectors from turning chaotic....or something like that.
This content is so great! Thanks for everything. I've just started to enjoy your older videos about drones. Amazing stuff! I wish you all the success in the world. You guys deserve it.
My wife and I recently went on a date night glass blowing class. The instructor had his lab set up with torches using DME portable oxygen concentrators used by folks needing oxygen therapy. The plus side was there was no danger from storing oxygen tanks. You can often find these for free or inexpensive from estate sales etc.
With a large circular glass container, you could wrap several tubes into a weave. The inner glass tubes would be invisible and the different color bubble tubes would make it look like the bubbles are being controlled inside.
Really cool you mentioned making the cut wet causing it to break better... I'm in healthcare and routinely have to break glass ampules of medication. I've always used an alcohol pad to grab the tip and snap it off because it breaks so much easier than just grabbing it with my thumb and finger and breaking dry. Super interesting that this is an actual phenomenon and not just some random thing I've noticed.
You never disappoint. Everything you show us is interesting and not always "mainstream". I also like that your family is a major contributor to the channel. Best wishes to you and yours for an outstanding 2022. Merry Christmas!
I love the mood between everybody in this video...great work on this front from all 3 of you great content too of course 🙂 Best Regards, Richard Mid Wales UK
Neon tubing is usually leaded glass which has a much lower coefficient of expansion than soda-lime glass and is almost as forgiving as borosilicate glass. The only restriction in working with it involves its chemistry. Leaded neon tubing is composed of up to 65% lead oxide, which increases the index of refraction and lowers the melting point. The torch used to work the tubing must have an oxygen rich (oxidizing) flame or the unburned fuel will reduce the lead oxide in the glass to metallic lead. This renders the glass opaque with a silver luster, not exactly what you want to pass light.
I learned something new today. This explains why the intentionally opaque parts of some neon signs looked like the glass was silvered. This effect stood out on signs where the opaque sections were painted black, and the black paint flaked off. It seemed weird that they would go to the trouble to get the shiny silvered coating between letters, and then paint them black.
Leaded glass also contains, well lead. I've heard it's generally safe to have leaded glass in the house but I'm not so sure I'd want to work with it (granted I did learn to solder using the lead based stuff, still not great for my health).
Thanks for all of your efforts! I love how you guys, somehow get a seemingly simple topic and turn it into a very interesting video! Always a treat when a new video is out. I wish you all a great christmas and new year!
I still have my very first ornament...a bubble-light...that I got in 1974 when I was 6 years old...though the incandescent lamp has needed to be replaced every decade or so. It is my favorite ornament and it hangs on my tree every year :) And...yes...I still love looking at it!
So very interesting! I actually have some Christmas bubble lights from my childhood that still work and still fascinate me. Clearly I need more! This is on my project list. Thanks!
Pretty neat 🤩 I love that I can watch any of your videos and learn something new or a different concept/application from what I could have known before.
I've been watching your videos for only a few days but because of the way you talk, I can listen you like someone I know for a long time. I would love to watch a Q&A
Your water added to the last few of the tubes acts the as the old "Shooting star" bubble lights did (same principle) which had oil in the top of the tube and a small amount of methylene chloride on the bottom. A really cool effect.
This was really cool! Nice change of pace. I enjoy ALL of your videos though. Answered many of the questions I've always wondered about as a child. This is much appreciated! I love understanding the "how's and why's" of how things work!
One improvement I would make to the process is having a container full of water below the tube when sealing it. I don't know how strong the narrow section is, but if there's any risk of it breaking, you probably don't want the tube to fall on the floor and shatter into a million pieces. The water can keep the tube from breaking so it can be reused, or at the very least, it should contain all the debris if the tube smacks into the bottom of the container and shatters (provided that it's fully submerged).
