It is amazing to me, that it doesn't cost more than it does. Cool to collect and will never be made again. I guess they produced tons and tons of it back then - keeping the prices low. Or maybe people don't like having radioactive things in their home anymore :o)
@kvykimo indelis It is if course less safe than non-radioactive glassware. But it honestly isn't that radioactive. In my opinion it is one of the safest ways to collect radioactive items. I personally don't eat or drink from it, because I have a non-radioactive kitchen. I follow the ALARP principle :)
Everything is magnetic, if you have a magnetar close by. But I don't recommend trying that at home. Go to a friend's house instead. Aight I need uranium glass now
ceramic engeneering is ,,,super complicated. glass is a really complex structure, it has 2 regions. a silica rich area..and a flux rich area. and you can fit all kinds of elements into it in a zillion different ways. ie..all the new metals in cars are actually glass now. they are super cooled liquids ..memory metals. same formulas..different production methods.
This was a very nice video, I’m always happy when you break out the Uranium glass. I’m also happy to see that, each video, it seems like you gain more and more patrons. Your work has taught me a lot, and I’m sure has educated many others. I just wanted to give you a heartfelt thank you, Brian. Keep up the wonderful work!
7:30 The supplier wrote that "Other substances are added to the beads for moisture-resistance". That sounds crazy. I cannot imagine how glass would not be moisture-resistant. Perhaps it means that if those other substances were missing, the glass would become a little dull and less shiny after contact with water or moisture. Thank you, this is great work and very well presented.
@ Paul Trigg I doubt it. The styrofoam is sitting on water, and water is good at discharging static electricity. Try making anything static electric in moist air or in contact with water ;) Thanks for watching!
Thanks for the quality vid before I lay down for bed, Brainiac! You truly are the highlight of my weekend! Also, thank you for the bloopers at the end. Love your stuff!
I used to have a number of uranated glass marbles; it was always a kick in the pants when I irradiated them with visible, NUV, or UVA radiation and watched them fluoresce! :-)
Well, I have been publishing a video every month for almost two years in a row now. As long as people have interest in my videos, I will keep making them. Thanks for watching and commenting!
I wonder if suspending nano particles of metal in glass (or another medium that holds its rigidity), would increase (or decrease) a given magnetic effect vs that of the pure metal constituent. I posit that the surprising magnetic effects you are seeing with metals in glass are due to this effect. It would be interesting to test this theory or (find papers that have already experimented with these properties).
What would happen if you spinned the giant neodymium magnet on a coil? With such a strong magnetic field im expecting a high enough voltage to power some stuff
I'd be curious to see if the gadolinium bead results would vary depending on temperature. Test it at multiple temperature points, say -20°C, 0°C, +20°C and +100°C.
@@Enjoymentboy Well even if the test lasts only 10s, that's plenty of time for the bead to cool down quite a few degrees if it was at 100°C and the air was at ~30. You'd have to use some kind of device that maintains its temperature throughout the experiment, or design another experiment altogether.
Gadolinium has something like seven unpaired electrons in its F-shell. That's why it's used as a contrast agent in MRI imaging. There's a difference between bulk magnetic properties and 'microscopic' magnetic properties.
You could test the effects of weight with iron fillings. The material would be homogeneous enough for your purpose and the weight of each test would be easy to control.
A video on magnetic flux permittivity would be interesting, maybe even magnetic saturation, for example I've heard super permittive metals can have a low saturation point and act diamagnetic. They can also be used in magnetic shielding.
Hehe, I'm not saying nice in a sarcastic way. Try turning on English subtitles. I'm actually saying no in Danish (Nej). It was quite a work to get all those tests done. Challenging, even for my patience... Thanks for watching!
I guess it highly depends on the concentration of metal in the glass. Some metals maybe have a stronger color (like iron, copper) and therefore need lower concentrations in glass.
I'm not so sure about that iron glass sample. In pig iron smelting, the casting sand turns emerald green from the iron contamination. Iron is also the reason Alsatian wine glasses have green stems. I believe your sample must be some other metal or an iron oxide rather than elemental iron. After seeing the tests, I believe it is Iron II oxide.
Iron show up in very different colors in glasses. In phosphate glass and also borate glass it always looks brown. Depends on the oxidation state. I lime glass it is green as you say.
It maybe possible the magnetic property is in the process of producing the glass bead, not just the metal properties in the beads. All these metals are produced, and the way they are produced can have an effect on behavior.
You should really make a Gouy balance to solve these problems. You have the capabilities and resources and it would be a great addon to your precision devices.
I believe that water drag isn't that significant in this experiment since the velocities involved are way smaller than the terminal velocity this boat should have with the beads. Maybe it's just the concentration of each metal in the bead that causes the ferromagnetic ones to be less attracted than the paramagnetic.
It's a LEGO flag. Being a Dane, I have quite a collection of LEGO from my youth (Danish company). Why not use it as an adult too x) Thanks for watching!
Tungsten (literally heavy stone) is the original name of the ore, not the metal. Calling the metal tungsten is a bit like insisting all iron should be called magnetite.
I seem to remember a video of a frog being affected by a magnetic field. Which would lead me to believe that anything can be affected. Then again maybe it was just the iron in it's body.
Funny, The thought emporium recently showed that you can cover glass with metal using Thermal evaporation so if it have even slight coat of any metal it could be magnetic... Another way to make glass or even plastic magnetic. 😅
Thankyou.. Can you do a video the electricity and magnets, Magnetic games is the only one who has done a brief video on it, I would love to see a dreamcatcher made of lightning..
Why this experiment was done by on not pure samples - all are mixes of diamagnetic glass with metals para, ferro and diamagnetic. For me it would be more important of measuring their magnetic force per weight of pure sample. That time we would get some information which metals have the strongest and weakest properties in respect to interaction with magnetic field.
I find it unlikely, that the styrofoam can have a static charge when sitting on water. Even moist air is effective at discharging static electricity. Thanks for watching :)
Physically speaking, it is anomalous that the heavier beads displace faster than the lighter beads; given that the weight of the beads directly influences the height at which the boat submerges into the water, thus serving as a factor in the direct proportionality of surface area and the drag that boat should experience, theoretically. This was not witnessed in practice. From a physical chemical perspective, what we witnessed in the video is what likely should occur because of the intermolecular forces involved amongst the polar compounds that take part in the experiment; Not just the bead and the magnet, but also water are polar. Water is the medium that was used in measuring displacement versus time. The countless attraction-repulsion interactions between each individual water molecule, whilst keeping in mind that as the bead on board the styrofoam boat displaces across water there are also momentary interactions between water molecule poles and the magnetic bead which essentially compensates for the resistance that should theoretically be experienced. Almost like when you visualize the energy and time it would take for one person going up the stairs versus the time and energy it would take for a larger person riding up the escalator.
I wonder if some kind of "pendulum meter" could be constructed to measure the force per unit glass. The period of a normal pendulum is independent of the mass of the bead, and therefore can be used to measure the force of gravity. You would need a uniform magnetic field and a fixed distance from the "pivot point" to the center of action of the force in the beads.
Uranium glass is good stuff. Gonna need to get my hands on some of that. I suspect ebay searches for it could potentially lead to an increase in prices. I did like the fact that some glass beads were repelled and some attracted (the cerium and gadolinium were great) but this could be down to polar orientation of the bead and if it was flipped over, it would do the opposite of it's previous reaction but it's and interesting effect making me wonder about the material alone, never mind the glass. Great video and keep up the good work.
Thanks! It did take a lot of patience to make this video. Both for the tests and the editing. HitFilm's timecode function is not made for this kind of use....
I have a suggestion for some new videos and they are related to light and lasers. Do you think you could look in to Vantablack, it this new substance that creates the darkest black yet know. It be interesting to see what differencing types of laser wave length will react with it. You could tested the difference between the lasers by look at the heat generated with a infrared camera on front and the normal method on the back of the object cover in Vantablack. You could also use a prism’s defragmentation of a powerful light source to see if are any wave that might be might still be seen on Vantablack. It’s just a thought. Thanks for all of your interest videos. Oh I just thought of something else, the Vantablack might be effective by a very strong magnet... carbon nanotubes I really don’t know much about them in general
Vantablack is very interesting, but also expensive and hard to get as far as I know. Since it is so good at absorbing light (and very fragile?), I think lasers quickly could heat it to destruction. But it would awesome to experiment with if possible. I honestly have no idea how it would react to a laser :) Thanks for watching!
I did not realize it was so expensive, that’s incredible depressing, they done things for artists in the past, if we could get them to see your channel ; I bet they would do something if they saw that you are both an artist as well as doing educational experiments. No harm in asking...
The weight effect maybe a area effect. The more frontal area you have of the material in question, the more total flux lines are going through the material (total Weber’s passing through the control surface). This should alone amplify any repulsion or attraction affect. en.wikipedia.org/wiki/Weber_(unit) en.wikipedia.org/wiki/Gauss%27s_law_for_magnetism Thanks for the fascinating videos!
#Braniac75 someday you should test the magnet proprties if different noble gases such as hydrogen ice cube, oxygen, nitrogen, helium balloon, neon, argon, xenon, and krypton bulbs! I love your channel!
Isn't ferromagnetism caused by the atoms arranging themselves into a crystalline form? If so, the fact that they are trapped in a glass probably explains why they don't perform nearly as well as would be expected.
I dont think the styrofoam was repelled by the magnet, the water itself is slightly diamagnetic which could make the styrofoam move away slightly due to the water movement underneath it
If you want to simplify comparisons between samples with different mass I would suggest a torsion-free string with a sample holder and counterweights made from inert materials (plastic?) Alexander von Humboldt used that apparatus to study Earth's magnetic field.
Thanks for the suggestion. I like the extreme sensitivity of the water bath test, but I guess a setup with leverage and counterweights could be equally or even more sensitive.
Hi. I like the video very much. And I have to state that I do not use Gadolinium in any other glasses than in the Gd glass itself and the Cerium glass.
Many people do because of the superstrong neodymium magnets. But they are mostly made of iron... Neodymium magnets are a crystalline combination of iron, neodymium and a little boron - not pure neodymium metal. Thanks for watching!
Put some printer toner under a microscope and you will find some pieces of strongly magnetic glass (a surface effect). They even rotate in 3 axis, corresponding to a weak old magnet held at 10-20 cm distance.
I like the sound when gadolinium glass was bouncing off the magnet.

I thank you for this. I love that you include experimental data and discussion of boat drag with correction for weight of the beads.
How about testing a solution of a gadolinium salt in water?
Then precipitating pure gadolinium silicate and melting that into a glass bead?
