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.
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.
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
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.
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."_ .
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.
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.
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!
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.
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.
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.
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).
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!
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!
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!
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!
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.
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 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!
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.
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
I really like what you did with those bases and the clear tubes along with the LEDs. It really makes it feel like the bubble lights are coming back someday and not just for use of the holidays but also for normal decorative house decor and environment decor use as well
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
I cannot tell you how much I enjoy your RUclipss. 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 RUclips’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!
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!
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!
Really cool effect. You could also use this with RGB LEDs and use them for custom PC case lighting. Have you considered using fuming solvents in a tube? It might be possible to get a smoke effect that you can then light with LEDs. Might even work with a piezo disc creating a fine mist and the air currents could then carry the mist up the tube.
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
I have made these in larger sizes (4 feet high, 1.25 inch diameter). I found that more details needed attending to. First, ANY trace of water (or dye) in the tube leads to a "chemical nightmare" in time (tube turns black, crud accumulates in the bottom). You sometimes see this in commercial bubble lights. I put the tube, necked down, in vertical fixture as you did, empty. Pump it down to 0.001 torr with pump, while heating to almost redness with propane (air-gas) torch, over its entire length, to degas the glass (as would be done when making vacuum tube or neon sign). Allow to cool while maintaining vacuum. Valve off pump, valve in solvent (set on T with vacuum line) until liquid level is a little too high. Valve off solvent, valve in pump, wait for some solvent to boil off until liquid level drops to desired level. The boiling solvent purges the last of the air out of the tube. Valve off & wait for boiling to stop (I cool bottom of tube somewhat) & seal off. When fabricating the tube bottom, I blow a little to get nice hemispherical end (to get glass thickness uniform, non-uniform thickness invites cracking!) then perform the flattening step. After that I fabricate a cylinder of glass that just fits inside the tube & is about as long as its diameter. Into the bottom of this I drill a hole partway through. In operation, this hole accumulates vapor from which the boiling can nucleate. I drop some broken glass shards into the tube, then the cylinder with the hole facing down, & then neck the top. Some commercial bubble tubes have this cylinder in them (turn them upside down to see). Even with boiling chips, the bubbles sometimes start violently. I have had the top of tubes blown off (on larger tubes such as my 4' one). The problem is that the boiling chips/shards, after the 1st use, have their pores totally filled with liquid. If you hit them shortly after starting, this usually gets things started. An idea I have had (but have not implemented) is to put a ring of some inert metal (nickel? chromium?) into the tube at the bottom & heat that by induction coil in the base. The metal must be inert to the solvent. The chlorine in the solvent wants to "eat" stuff! By concentrating the heat in a small area, the likelihood of flashing on start is lessened, & less heat is required to run the tube. Do not put dye in the tube! If you want color, slip a cellophane sleeve over the tube. This also increases contrast in lit rooms, as the light filter rejects room light not the same color as the light refracted from the bubbles.
I love how this channel has a real “Mr. Wizard” feel, but I enjoyed seeing the sort of behind the scenes dialog about the rotating mount.
Exactly what I was gonna say, shout out to my man THE Wizard
@@jeremiahbullfrog9288 those kids grew up to invent the internet lmao #worth
I came here to say this but I’d like to add “swole mr wizard” : don’t disrespect science like I disrespect these weights.

Neat stuff. I might try this. I really like the water layer effect.

Or you could just use a hole saw made for ceramic and glass. Still use water but a piece of soaked sponge cut to fit inside the bit is enough.

"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.

When fabricating the tube bottom, I blow a little to get nice hemispherical end (to get glass thickness uniform, non-uniform thickness invites cracking!) then perform the flattening step. After that I fabricate a cylinder of glass that just fits inside the tube & is about as long as its diameter. Into the bottom of this I drill a hole partway through. In operation, this hole accumulates vapor from which the boiling can nucleate. I drop some broken glass shards into the tube, then the cylinder with the hole facing down, & then neck the top. Some commercial bubble tubes have this cylinder in them (turn them upside down to see).
Even with boiling chips, the bubbles sometimes start violently. I have had the top of tubes blown off (on larger tubes such as my 4' one). The problem is that the boiling chips/shards, after the 1st use, have their pores totally filled with liquid. If you hit them shortly after starting, this usually gets things started.
An idea I have had (but have not implemented) is to put a ring of some inert metal (nickel? chromium?) into the tube at the bottom & heat that by induction coil in the base. The metal must be inert to the solvent. The chlorine in the solvent wants to "eat" stuff! By concentrating the heat in a small area, the likelihood of flashing on start is lessened, & less heat is required to run the tube.
Do not put dye in the tube! If you want color, slip a cellophane sleeve over the tube. This also increases contrast in lit rooms, as the light filter rejects room light not the same color as the light refracted from the bubbles.
i just love how much stuff you can make at home! i never expected to be able to do almost any chemistry at home :)
Wow I'd like to have one to sit on my desk. Awesome video
