  • will u marry me !

  • Why is this video age restricted? It shouldn't be by my estimation.

  • God i wish i was good at chemistry

  • It seems you are trying to make pure ZnS and avoid contamination. But I recall you have a TIG welder (argon gas) and a home furnace (clean high temperatures). Therefore you might try putting your zinc powder and sulfur mixture in a tube in the furnace under a flow of inert gas? This is closer to how a chemical laboratory would do it. Put plugs of glass wool either side to keep it in place.

  • How cool! I believe using a penny may cause concentration quenching by having too much Cu in it. The best ZnS:Cu phosphors have around 0.01% Cu whereas pennies have 2.5% total and 0.8% in the "zinc" core. That may be why there is a such short glow time.

    Nonetheless, its a very cool video.

  • Thumbs up if you don't understand this xD

  • I think I just fell in love with you science lady.

    Maybe I could come over and we could talk about batteries over some cake and coffe.

  • 2:13

    It has sulfur in the place of oxygen. Nice video!

  • hello Jeri. I'm from thailand.

    your Idea is very good.

    but my country no have Tarn-x.

    What can I substitute Tran-x.?

    What should I do.?

    thank you for good idea.

  • Cool video. Hydrogen Sulphide is indeed very dangerous, be careful folks.

  • DynaDuctINC wouldnt that mean you would have a glowing dot in ur blood stream...?

  • Try flooding argon gas and see what happens. Oxygen is more reactive than sulphur . I am going try it myself. I have argon!

  • Do you know of any chemical that can be safely injected into the blood stream in order to glow for a short amount of time without side effects such as death? Like luminol but without the death.

  • @DynaDuctINC I don't. Wouldn't that be cool if you could?

  • @jeriellsworth because I calculated the exact amount of sulphur and zinc that have to react to produce the zinc sulfate (and added a bit more of sulphur just to be sure that there wont be any extra zinc to burn). Than I mixed those two REALLY well and when I reacted them, it was so well mixed that the mixture reacted all at once and exploded rather than burned, the reaction lasted about one second.

  • @jeriellsworth I got excellent results in producing extra pure ZnS, though I didnt try to make the glowpowder yet.

  • @kzalesak4 How did you test that is was pure ZnS and not contaminated with ZnO?

  • isnt it easier to just mix zinc and sulphur and ingnite them (caution, if you use more than 10g of the mixture it can explode) and than mix in the copper powder to the product of this reaction (powdered ZnS)?

  • @kzalesak4 So far my results were very poor just burning sulfur and zinc.

  • Filing on the lathe can be dangerous. If you really must do it, a tip is to run the lathe backwards, if possible. That way the file will not be driven into your hands or chest when (not if) the chuck or workpiece grabs the file. A filing rest is also a useful lathe attachment for doing this sort of thing. Preserve those hands to bring us more of your great videos!

  • that is pretty cool ! I wish I could buy some bulk zinc on the cheap !

    that zinc sulfide phosphor looks a lot like the phosphor in one of my older scopes, even the afterglow time looks about the same

    I bet a slightly more refined process would yield pro-level results

    maybe using purer stock and a refractory oven with J thermocouples and you'd get more consistent results ?

  • @nabiul2 Did you seriously feel it even *might* be appropriate to leave that comment? Here's a suggestion: look up Jeri Ellsworth on Wikipedia, even. I'm sure that you're a fan of citing it as an informational source, so go ahead and find some information on how much more intelligent and skilled she is in comparison to yourself.

    Have a great day, - Christopher

  • @ChrisKarr Just because you're too stupid or unqualified to spot dangerous experimentation methods does not mean that you can declare what someone else is doing as being safe, regardless of their qualifications.

    This 'intelligent' person first begins by trying to cause a chemical reaction with a butane lighter, she then uses a direct flame from a blowtorch to burn away the reactants and produce nothing but metal oxides and dangerous vapours.

  • @nabiul2 So, you open by directly insulting me? That's very admirable.

    Also, what's the point of doing anything if it's not experimentation? You're so very closed-minded. If you're a scientist, you're going to be spending the rest of your life trying to verify the work of others, since you're obviously not fond of a new idea.

  • @ChrisKarr As if that wasn't enough to give you an indication of her 'intelligence', she then uses the blow torch, capable of melting glass, to ruin a test tube. The bright yellow flame is actually the test tube 'burning'. She then goes on to using a bolt...which is a hexagonal shape to 'cork off' a cylindrical test tube...

    Do I need to keep going?

  • @nabiul2 Where does she use a bolt as a stopper?

    She used the blow-torch because it's the tool she had on-hand and which would be most-efficient at heating the reactants quickly.

    So, since she's melting a test-tube, you feel the need to insult her intelligence? I must say, you must be a sad, sad person to feel it necessary to insult others in order to feel good about yourself.

  • @ChrisKarr Around 0:37; you clearly did not watch the video or listen to the commentary. Experimentation is not doing random things and hoping it will work. She uses a lighter for gods sake to try and melt metals.

    Yes I need to insult her intelligence, any one with a simple working knowledge of chemistry would realise that there is something wrong with trying to melt metals inside a glass 'crucible'. I could say more but this is a waste of my time. Send her a marriage proposal already.

  • @ChrisKarr Don't let nabiul2 troll you. He's just feeling threatened for some reason.

  • @jeriellsworth "any one with a simple working knowledge of chemistry would realise that there is something wrong with trying to melt metals inside a glass 'crucible'." - nabiul2

    Well, what about aluminum or copper? Anyone with a 'working knowledge' of chemistry knows that their melting point is high above that of zinc...but look at what happens when Cu or Al contact liquid Zn - they dissolve. Hmm...maybe that happens with S and Zn(?).

    He's threatened by your intelligence, so he insults it.

  • Wooooh :o

  • I should also add that the white smoke wafting out of the top of the test tube and the bare powder on the plate is zinc vapour. Zinc has a really low boiling point of around 900C, INHALING ZINC VAPOURS WILL GIVE YOU HEAVY METAL POISONING.

    Look up metal fume fever.

    Extra information like this is why you should not emulate anything that 'home experimenters' and 'hackers' do without fist learning about the dangers involved with the materials that you will be using.

  • @nabiul2 Yes. Yes. We all know not to weld galvanized pipes for this reason.

    BTW. Zn and S can be ignited with a low temperature flame when in a fine enough powder form and I was not trying to block the fumes coming out of the tube with a bol, but limiting the oxygen entering the tube in a similar way describe in a patent for making ZnS

  • thumbs up for kitty! :D love your ... scientificy! (A) :P really cool stuff!

  • How about customize brains, i am sure all blonde girls will need one, dude Paris Hilton too. You would be so rich^^

  • @merdadocaramba Another pleased customer!

  • Jeri, you are taking some big risks with nasty stuff.

    I expect you enjoy that, but sometime around when you lose your sense of smell or have your second or third explosion/fire remember your life is valuable.

  • @tomson600 Bah. No worries. :)

  • This is great, Jeri. I actually have a use for a low-persistence phosphor--though I was going to have to take apart an old CRT...

    If you refine this, please give us more (and weights and measures, maybe).

    (CSC still sucks.) 

  • she probably cant cook neighter:)

  • 0:20 xD

  • make a video how to build a atom bomb

  • you nearly burned your kitteh!

  • @Arishava Kitteh is very good at running away when the fire comes out.

  • Very Cool!

  • Gold Jeri, you nedd to make Gold!.

  • @Albinorama he will have to use huge ammounts of energy, but it is possible to make gold ;)

  • Hope u don`t turn evil...or we`re all screwed!

  • You're like the scientist my 12 year old self wanted to be, but cooler.

  • Excellent! At home chemistry is awesome!

  • why is there only 1 of this woman... <3

  • Very interesting. Thanks for sharing.

  • I love how the laser draws patterns in it at the end.

  • Be careful kitty.

  • @spektrum1983 Kitty is fearless like me.

  • How about making some thermocouples. Then you would have a way to monitor the temperature and not overheat your mixture. Also, could you have used your "Easy Bake" furnace to have a little more controlled heating of your chemicals.

  • Very interesting, keep it up. 

  • This was very confusing.... too much and too short to understand what you actualy did there.

    Maybe you can make a simple "slow" :P video only about the experiment that did work?

  • @morto360 Sorry it was so fast. I will continue refining this process and post updates.

  • My attempt to do this a few years back wasn't very successful, but I did get some particles with a bit of persistence. I also got some orange-glowing particles.

    Do you have an argon tank? Maybe try a blanketing atmosphere?

  • @vk2zay I got some orange glowing after trying to use it for an EL display. I did see some brilliant green specks in the EL operation, but it was very sparse.

  • Three videos in two days! It's going to take me ages to get down from my Jeri high.

  • More kitty videos!!

  • What? Still no fume hood?

  • I burst at laughing at, "It's just a Gottlieb".

  • Your really inspirational. Thanks for all your videos.

  • Flowers of sulfur(sublimated sulfur)? You said you can get it from the drug store, is this what you should ask for or does it have another name?

  • Hi Jeri,

    Nice tutorial. Can this be used in EL wire ? or is it purely a luminous powder

  • @Harani66 There seems to be some that works in EL mode, but very sparse.
