The precursor to yellow.
i get what i deserve
@@ExtractionsAndIre To improve efficiency:
- spread out your product as much as possible (a big and level! glass plate)
- relocate the lamp outside on top of the lid > cut the hole in the lid big enough to not waste uv on exposed plastic and glue the reflector on. (Again, reflector completely outside the box)
- cover every last gap and any nonreflective surface with aluminum foil, since at the high reflective intensity even a little gap will waste a lot of light (think of how a laser works for example)
- maybe use less solvent... I don't know how much it absorbs your wavelength...
- maybe consider using a makeshift filter that only lets your wavelength through
I hope this was helpful mate 👌
Let’s play the game - yellow, tar, or yellow tar - place your bets!
@@excitedbox5705 Does it output the right wavelength? UV LEDs generally doesn't.
@Patrick Hudson yeah it wouldn't be on-brand at all

The vaguely circular scrawl marking where the hole should be, the power tool waving menacingly yet impotently in its direction, the ineffectual hacking to try and actually remove material then the final step of getting your dad to do it because he somehow knows the right wizardry to make the tools do what you want.

“I’m gonna need a ballast, and I don’t know what the fuck that even is.”
Story of my life.
Negative differential resistance is weird.
It's when you have a good meal a couple of hours before going out on the piss. A bit of ballast always helps.
A ballast is an inductor placed in series with the lamp which limits the current flow through the discharge tube to the manufacturers specification. Think of it as an AC resistance.
"It's definitely gone yellow... fuckin of course it has." lmao
Water purifier UV lamps are super cheap and should be easily available. The circuitry for a regular fluorescent tube light will light it up okay. That should be plenty enough UV for your TLC as well as your π-π* transitions. Bromine cleavage might happen too, but may be worth a try. Also, a simple wooden screen is protection enough. The guys in my lab used this crazy water cooled high pressure mercury lamp for photochemistry in a wooden box.
Finally, copper sulfate is a convenient UV transmitting filter. And finally finally, your molecule might be a bit too non-polar for TLC in DCM. Perhaps consider 10% acetone in hexane?
That's UV-A; I think he wants UV-B, which is more of a tanning bed kinda lamp.
@@sebastianramadan8393 No, they give UV-C and some other also.
@@sebastianramadan8393 Tanning bed bulbs (They use a combination of bulbs to achive this) are almost entirely UVA, like over 90% UVA. Even reptile bulbs are mainly UVA also.
@@sebastianramadan8393 emission peak is around 254 nm. It's what you use in TLC visualizers. With a filter it might be possible to block out the higher energy stuff without too much attenuation. Again, it's probably all about fun with jugaad.
@@rdizzy1 he needs low UVA or high UVB. Tanning beds, and photography blacklight bulbs. philips suffix /09 and /08 and osram /79. The USA marking will be BL or BLB. You can also take a pyrex flask with a little bit of mercury in it and run ~500w through a tungsten filament inside. He has a vacuum pump to pump it down and adding a little heat he can adjust the pressure. aquarium stores sell little test cards that glow under specific wavelengths.
Yesss I finally caught a live one. Thanks for taking me back to my glory days as an organic chemist. Those sure were... times.
Healthy times?
@@ExtractionsAndIre Only the freshest thiophosgene cookies in my lunchbox.
Two tips for you: No1 more Watts definitely help, No2 oxygen tends to be a pain in the arse in photochemistry so it often helps if you deoxygenate your solution (by bubbling inert gas through it for instance)
Glove box time?
Worried for the poor soul who has to do an enema with the reaction products.
So, I'm not the only person who heard/thought that same thing 😂
Do you normally know people to do enemas this way or are you speaking from experience?
@@cwtrain yes
How much explosive yield would a hypothetical rectal insertion pill capsule filled with octonitrocubane actually have tho? That would be multiple gram amounts so probably enough to turn your asshole into assholes.

@@ExtractionsAndIre you make a good point, I guess that's what I'm here for.
This series has given me hope. Hope that one day I'll stumble upon someone who's inexorably caught up in a long, frustrating, befuddling project which repeatedly gives the illusion of having been completely in vain, so I can heartlessly comment...
*Laughs in Cubane.
I totally get you
Chris from clickspring says hi
*laughs in antikythera mechanism
Your TLC is still far too polar, try using a petrol/DCM mixture.
+
I want to like your comment. But it's on 69 likes.
Maybe even a petrol/carbon tet mixture if its still too polar
And maybe a good drizzle of olive oil to finish
yeah I would guess around 10-20% DCM in hexane
Agreed… don’t know if ethanol fuel would work tho
I was thinking a 5V computer fan could be mounted to your bin as a cooler so you could ventilate it better. just biff in a thermocouple with and if the temperature stays low/stable you can build some confidence in longer run times (though it’s a pretty safe rig)
Really I’m just commenting to feed the algorithm lol
That's a reasonable thought though!! (All hail the algorithm)
@@ExtractionsAndIre yeah dude just let it run for two months if it works slow it's not like this series is in a hurry
Yeah building on this I made an exhaust for my resin 3D printer enclosure using two 140mm PC fans and a usb set up converter. Just snipped off the barrel jack, wired in a pc fan splitter, and boom both fans run at their rated speeds at 12V via usb. Things like $5 off eBay
An Aussie summer would laugh at you. An Aussie winter would chuckle and say theres snow else where.
Tom, usually not overly concerned with safety: yea I put the lamp in a box to shield me from uv
Me, with like 10 high output uvb tubes in my living room for my reptiles: oh... Oh...🙃
Glass blocks UVB really well, I don't think you have much of a safety concern
@@someirishkid9241 I forget, but do the reptile lamps put out UVA? I know they output uvb obviously lol but not sure if they put out some uva that would add up with 10 lamps ya know. If they do then you do have stuff to worry about as glass does not block uva
@@cwill2127 ignore that deleted reply lol I was being dumb. Yeah you're right, that's worth looking into
@@cwill2127 Yes, they are usually even more UVA than UVB, like 3-4x more UVA.
You assume glass is involved, a fair assumption, but I mostly use mesh. It reduces uv output a fair bit but not nearly the same as glass
Honestly, the bulbs are never directly in my line of sight when I'm not fiddling in their cages, and they are all at least 10ft from where I sit. I think that limits any real risk of harm to an acceptable level(I'm also subscribing to the fast and loose method of health preservation we see tom display at times)
I exclusively use T5 HO arcadia tubes in curved reflectors. They have fairly moderate uva levels vs these garbage cfl units. They have a fairly fast(short?near??) output dropoff in uv which gives me some comfort(valid or not)
Got to admit when he said "we're going to use half of the monoketal" I started to sweat.
I love that the "safety consideration" is an opaque plastic box with a hole drilled in it for the lamp. Just made me crack up. This channel is really a hidden gem

the tlc bit was the best part of it. Loving this guy more and more, hes starting to put out some really good stuff.
Apparently my other chemist idol, nilered is just focusing on moving and doing shorts so this is like the best chemistry channel on youtube at the moment.
DCM alone is often much too polar of an eluant for the type of molecules that you’re working with.
Life is not worth living when DCM doesn't work for something
I literally just started rewatching the beginning of the cubane series XD
Haha same literally watched them all about a week ago. Soo happy when I see this. 😄
Great minds think alike!

After spending the last 2 weeks binging everything you have on both channels, I’m SO excited to see new content in my feed! Hope the PhD/thesis is going well!!
HELL YES!!! Made my day seeing an upload from E&F!!
It’s been one year, ten episodes, and a lot of chemistry and I still don’t really know what Cubane is or what it does or is used for. Yet I still keep coming back for more
It is exceedingly energy dense and given the right modifications makes for a rather nice superexplosive
@@KT-pv3kl allegedly. Who knows if the reported properties of octanitrocubane are even accurate lol. Who has validated it?
Big boom molecule
The bonds are strained. The energy to force them in that position is large.
That means the energy that will be released when those bonds break during combustion is also high. Cubane is used in explosives.
Now that's what I call some scuffed photochemistry.
The cheering and confetti for "tar" gets me every time.
I really like the way you filmed this episode, it feels like a real step up.
hey thanks!
Im glad you got through schooling and are back at it, i do much appreciate your work
Love the progression on the chalk board madness
There's always carbon arc lamp, but I don't know if the wavelengths would be right. I think I remember you having a power supply that would work, and electrodes out of lantern batteries work great. Pretty easy way to get make your eyes go crispy levels of UV.
Easier to just buy a uv tube on eBay and not piss about with the heat and amperage problems of arcs
@@iNerdier Oh definitely! I was shooting for cheap to free in a time frame of soon to immediately rather than any other concern. The more I think about it the more having a naked ark around all those solvents seems like a _bad_ idea rather than merely a silly one.
Thanks Tom for keeping it real! This is how it goes, the pleasant struggle. Hard to find such entertainingly authentic content. Your channel is a refreshing spring in a lonely desert
I love this series!
Some advice from a fellow chemist:
1. Photochemical reactions need some time. And with some time I mean a long time without any auxiliary substances. Especially with this low power lamp. I think u need way more patience.
2. Try using different solvents to develop the TLC. A standard system in our lab ist ethyl acetate:cyclohexane. It's way cheaper and better for the environment than DCM.
3. The staining solution looks quiet good. But try drying your TLC plate before using the staiining so it can soak in better.
4. I would use something to stir the reaction mixture. It might reduced formation of the byproduct - especially this dilution.
This series has been keeping me alive
Two things come to mind... A different geometry of reaction vessel to maximize the UV exposure while also allowing for stirring (how UV transparent is the solution?) and putting the reaction vessel as close to the lamp as you can without it getting too much heat.
Quartz tube! Quartz tube! Put it in a quartz tube and it'll be done in six hours! Also, have you checked how uv-transparent your solvent is?
Aus stralia is a third world sh*t hole that cant afford quartz.
a year ago i had a youtube beef with someone who tried to convince me that normal glass is 100% transmissive for UVB, if this was the case we wouldn´t need quartz cuvettes in UV/VIS spectroscopy
I'm pretty impressed with the progress you did manage to make holding those drilling and cutting tools with only your outstretched foot.
concentration of solute probably didn't matter because this reaction step was about an internal reaction within the monoketal, so diluting it if anything reduced side products
Gotta say, your sound/video editing on this one is top notch, that was really enjoyable to watch!
Yay! A new Cubane-Episode! I am an electronics engineer but honestly, i love this channel and its arsery with fast and loose!
... I have to start to use this term at work... :)
I felt real pain watching you use that drill. I hope some of that was embellished for the sake of the video.
Truly painful experience
You really need to melt these PET containers to have any decent results. Drilling always results in cracks
it's half drama, one quarter chemistry, and one quarter irrelevancies
"If only I could be so grossly incandescent".
\[T]/
This is the first new episode of the Cubane adventure since I subbed to this channel, it's a magical feeling.
Wow, these music supplemented clips really added to the video!
Personally I'd use a much smaller box for the lamp. You don't need to illuminate the entire box when all you want is for all the light to get into the tube, s shoebox would do.
But, you can probably engineer (lol) some kind of paraboluc reflector to go behind the testtube and really focus the light (more light = less time, ammiright?)
Just finished rewatching episodes then I see this uploaded five mins ago! Woooo
Loving this series! Really hope you get it working :)
Bro, Loving how the video quality is going up. Pleasure to watch.
Keep growing that beard, a few more weeks and you'll look like a mad scientist
That a KND pic?
Love ya work boss 💜
My sides at the yellow tar at the end. You keep doing this to yourself, but goodness am I here for it.
love it when there's a bit of maximum craft going on
"Thanks a lot"
"Not a prob"
Most Aussie father son moment so far.
Ohh now I get it. This is another turbo encabulator. You've had me going for the last few episodes, but it finally clicked that you're using cyclopentane instead of cyclobutane. Also you're calling catalytic formation cage formation via photon diffraction. Keep up the good work.
This man is the reason why i still haven't dropped out of grad chemistry (not that i know anything worthwhile) always fun watching you Tom! Need more explosions and fire videos
I needed this channel in my life
Anyone else really like the music choice in his videos? It has the garage chemistry vibe
I know nothing about chemistry but your videos are still funny and interesting
I absolutely love the gamecube intro, cracks me up every time
"Once a year we have a week of rain, and then that's it"
Jesus it's literally the opposite of England, we have two weeks of Summer, one in August, and one about half way through May. The rest of the time it's grey, windy, cold, wet, and shit.
I love it tbh.
Everything I see on this channel simultaneously makes me want to take up chemistry as a subject and also never do any chemistry in my life
camera work improvements seriously showing!! top job
OMG, another episode! This made my day!
Glad to see ya buddy thanks for sharing video with us hope you are having a great day
I need to see you on the safety third podcast, I feel like you’d have some stories to toss around
It happened. Worth its weight in gold fulminate: czcams.com/video/mE2kc-G0yx8/video.html
Idk if they are available in Australia but a UV water sterilizer would be fairly easily adapted for this. Different systems are designed differently but most of them are just a quartz tube that runs next to a UVC germicidal bulb. IT should come with both the bulb and ballast so the only modification you would need to do is plug both ends (with suitable plumbing fittings) and then you have a fairly nice UV reactor and with some research, you should be able to find different UV bulbs to swap out giving you different reaction condtions.
Wow I really liked the music this episode!!!
So glad to see another video from my favorite Aussie

On a scale from 1 to cancer, how unhealthy is accidently inhaling DCM vapors?
DCM by itself isn't that bad I believe it's even used in some medicines tho that's not inhaling so it's probably not great with the lungs, the real scare with DCM is that it can take anything dissolved in it with it when it passes through your skin
Not very different from other common solvents, I think. It's quite usual to have a little sniff of DCM, when I'm working in the lab even under a fume hood. The major problem, I believe, is that you can't perceive it unlike ether or ethyl acetate, so you can feel dizzy pretty much unexpectedly.
Depends on the amount you inhale. If you inhale a lot it's in the "Cancer *and*" category. In particular, it comes with lots of lovely poisoning too. If you inhale a little, it's just in "mild cancer maybe".
It's not a proven carcinogen, the main danger if inhaled is that it metabolises to carbon monoxide.
@@Isolanporzellator That injection case.... fack me dead
5:30 Just heat up a coffee can and push it into the plastic, ez hole.
doesn’t work - the can either doesn’t punch through (it’s a surprisingly high amount of mass to heat) or you end up with a melty/burny mess of a “hole” that’s way bigger than you want
You’d need it to be red hot and if you fuck it up you could warp the whole box out of shape.
@@andrewjvaughan You can reheat the can, just place it in the same spot again if it wasn't hot enough in the first place. Do this outside if possible...

Was anyone else expecting a portal to open up and a time traveler to jump out and stop Tom from plugging in that lamp like right at the last second?
I've got to admit I'm kinda bummed.
After seeing you use the power tools, I can understand why you didn't go into dentistry :-)
My favorite youtube series!
I like your working standards!
I'm sure your dad could make a mercury lamp out of a glass tube, two nails, a resistor and some patience. Have the nails act as an electrode on each side of the tube and somehow manage to evacuate and seal it after getting a tiny amount of mercury in. Wire it up using the resistor to limit the amount of energy going in and boom. Easy peasy enemahr squeezy.
What we need to do is select for enzymes that can catalyze this whole process. Room temperature cubane!
Ooooooh, is there any (public lol) research on enzymatic catalysis (or even biosynthesis via genetic engineering) of energetic compounds? And would it count as a bioweapon?
@@nibblrrr7124 Not that I know of. But considering some of the weird biomolecules out there I see no reason to think it wouldn't work.
