NurdRage - 2010-04-30
In a previous video i showed how to make green glow in the dark powder. Old video here: http://www.youtube.com/watch?v=TYDn06G2C0E simply replacing the original strontium nitrate with 590mg of ultrapure calcium nitrate tetrahydrate will make a blue glow in the dark powder.
That's fantastic. Science has never been my thing ever but you very much keep me interested in the project at hand. Plus you explain why the project works and how its working. Thank you very much for these videos. Have a wonderful night.
Nurdrage, What would happen if you mixed in a slightly radioactive element? Would it improve it's brightness or glow time? That would be a really cool video.
What will happen if we use magnesium nitrate, or barium nitrate instead? I just want to ask about how different nitrates of alkaline earth metal work with the formula. Thanks for your listening.
Hi Nurdrage, I want to ask where you can get all these glass vials. I found that they are quite expensive, so i'm trying to look for some that are cheap and durable (also with a cap). Thank you!
so far, all commercially available glow powders are much dimmer than glow sticks. So if you want glow stick brightness, glow powders aren't the way to go.
@TheScienceTestTV barium nitrate makes green, so might as well use strontium nitrate, which is safer. copper and silver produce dark oxides, and thus unusable. What reference or theoretical background are you basing your selections?
Can you show us how to make blue glow in the dark powder? It would be very much appreciated. Thanks for all your hard work.
@DonaldValverde A strange coincidence maybe, but once I had enough general information to understand some of what is going on in NurdRages videos, I could pass Practice AP tests after watching them all. Very informative.
How can you predict what color will it glow? I mean, do you experiment with bunch of stuff and see what color it glows, or use some theory?
@Landau Martin The people at Seiko watches have experimented heavily in this. Substituting B or Ga for Al might work. Ba for Sr might work too. This keeps substitutions in the same chemical family of the periodic table.
Do You swap the strontium nitrate with europium to form a red glow?
how pure do you think it needs to be? If you have nitric acid and limestone (chalk) you should be able to make this. Maybe if you re-crystallize a few times.......
where do you get all your materials and chemicals from?
So do I understand you correctly (reading through comments below) that the presence of the metallic elements produces the various colors (much like flame chromatography)? Ergo... assuming that understanding is correct, almost any metal-nitrate compound could yield a different color (Mg already excluded)?
What if you did something crazy, like Potassium as an example. Will any nitrate glow at all? If so, would the colors be much different, or still greens and blues
@TheScienceTestTV Empirical research is a crude but valid approach. If you should find the right mixture post a video on your composition mixture and results.
@TheScienceTestTV ammonium nitrate does not have any metal in it, so it won't work. Magnesium nitrate just produces non-fluorescent powder.
Hay sir can it be used in textile? Green glow dark pouder please answer
do a video about the glow in the dark ink they use for tattoos... that would be interesting
Why don't you use/add the molecular formulas with the chemical names? equations with reactions?
how about making glow in the dark gel or slime?
but will it blend?
hello, i'm new to your videos, but it is quite interesting. maybe some tips: -try to use beryllium nitrate, magnesium nitrate, or barium nitrate -try to use gallium nitrate:P(i dont know if it even exists anyways) -try to add common nitrate salts -or add other rare earth metal salts -or transition metal salts -or sodium silicate, i heard some kind of glow powder that contains silicate ... well, thats my idea, hope you find this creative... (huh?) good vids anyway!
Hmmmm I wonder how long it stays lit. Gotta check the other video I guess.
@DonaldValverde chemistry textbooks for high school and university students are great places to start if you want to get into the core of chemistry and learn the fundamentals. It takes a LOT of time to get through all of it. But at the end of it you'll be able to truly understand whats going on, why, and how to make your own experiments. if you just want a bunch of experiments already thought out then just scour the internet for "how to make X" websites. problem is not all of them are good.
that is beautiful
It looks like there are fewer dead flakes, but it lasts just as long-- is just a weaker reaction overall? ~ Jethro.
@cautionnow6 sometimes, try to keep it scientific though, like if you want something like sugar snake, no way, but if you want something like "the synthesis of potassium trichromate" then maby
@TheScienceTestTV I already told you ammonium nitrate has no metal, so it won't work.
Awesome!
the macarena video is about the laws of solubility they changed the lyric for the laws of solubility for those wondering. anyway good luck on future experiment and I'll be watching your upcoming video.
@FLAMEBOY98765 Who knows...try it yourself...of COURSE it will blend you tard...it's powder... @NurdRage Now im curious...what would happen if you mixed the two? would the chemicals perhaps cancel each other out or perhaps make it stronger? maybe even a new color (even though green isnt considerd a primary color) :P? you should try it with some of your drawer full of glow powder! xD
...and I guess the mechanism for photons in the glow stuff...
what do you think this video is about? making a blue pie?
What does the Macarena have to do with anything?
Awesome.
there is nothing nerdy about your videos.
What about red?
I took a organic chem course and i know what u r talking about now XD
@EdwardNavu barium is green, magnesium doesn't work
after 10 minutes it slowly turns violrt to red
@NurdRage there is a video in the relatec section about the macerena
@ryans32123 haha "releases it when its dark" :D
@jonvagnier Someone needs to watch the video one more time!Who could it be......THIS GUY
NurdRage rules
Cool
the powder looks like crack.....
why do you guys hide your identity?
is that your voice?
is this your real voice or computer generated??? kinda doesn't sound all really! srry if it is :D
The Thought Emporium - 2012-03-17
have you tried this with magnesium or barium (nitrate)?
