This project was a disaster. 

“Humans can heal but expensive recording equipment cannot”, wow I don’t remember seeing that in the highschool lab safety packet.

The only difference between goofing around and science is documentation.

16:40 the comedic timing of "we can glue this back together! *glass shattering* oh no!" just had me in stitches

Nile red: the most precise chemist Nile blue: “yeah this looks good enough.” “You know what screw it let’s add it all”

This is the biggest contrast possible to the previous "chemistry safety" video

*Burns down lab* NileBlue: "Damnit. We had no footage, let's rebuild the lab and do it again"

Nileblue : I keep losing stuff. Also Nileblue : *smacks glove on the floor, chucks safety glasses in the air, tosses tongs off the table*

NileBlue: "It's 2200 Fahrenheit" Also NileBlue: "As you can see, it's a little warm in there." NileBlue is just built different.

“That glow is a good indicator that it might be a little warm”

16:38 "We can glue it together!" *GLASS BREAKING* "Oh no!" COMEDY. GOLD.

The lack of practical engineering chemistry guys have makes me smile. Like, yeah, I'll never be able to synthesize acetaminophen, but I know if I cut out a piece of insulation, that piece is a perfect template for the replacement.

When he drop-kicked and caught the tongs at the end, I was blown away. Incredible skill

I like to imagine this isn't his. He just randomly found a high school / college chem lab umlocked and started messing around

Nilered: lawful good Nileblue: chaotic good

I’d argue that Nile’s personality was the most fascinating thing in this video

RE: Safety. DO NOT wear nitrile, rubber, latex, or really anything synthetic when doing work with high temps. It can easily melt and cause even more damage then just bare skin. be safe.

NileBlue in May: *SAFETY* NileBlue in June: _You'll recover..._

This is the most intelligent episode of Jackass ever filmed.

"So far, the oven has survived." Scary words from a chemist, tbh.

I like just how much he likes the person behind the camera. It really shows. He likes to entertain him and he is often looking up with a smile looking for his approval. Its really cute.

"Remember, kids, the only difference between screwing around and science is writing it down." Or in this case, filming it.

Nilered: I’m doing this in my fume hood and behind glass to protect me Nileblue: I hope it explodes

Remember: "the only difference between science and screwing around is writing it down" So 2:25 is absolutely true

NileRed: I'm going to synthesize aspirin from a regular battery, using this elaborate chemical process. NileBlue: I won't sleep for a week until I make this glass explode!

NileRed: What chemistry teachers tell their students. NileBlue: What chemistry teachers do when their students aren't around.

i dont understand how a person can talk so calmly yet emit so much chaotic energy at the same time.

16:52 I can't help but notice how angry that power outlet looks

I now understand that the room that the chemistry teacher has in the Chem lab isn't a fish tank, it's a little protective thingy you put stuff in and watch explode. Edit: it's been 11 months, I know what it's called.

NileRed: Professional Chemists NileBlue: Throws stuff on the desk. Is there sauce on my face. We can glue it. *smashes jar in sink*

NileRed: perfectly composed, calm NileBlue: "hold my beer"

This guy has the most Chaotic Calm energy and I love it.

So now after reviewing of content its confirmed that NileRed and NileBlue are indentical twins with different ideas but both giving us same interesting and educational videos

“We can glue it back to together” *sounds of glass breaking offscreen* “Oh no”

Him saying “That’s kinda infuriating” in the calmest voice ever has so much scary chaotic energy

NileRed: professional scientist NileBlue: guys that just started doing chemistry and don’t at all know what they are doing

NileRed- acts like an adult and is very serious and is trying to avoid anything dangerous NileBlue- a couple of teenagers messing around with molten metal and blowing jars up

Every episode of Nile Blue feels like it was filmed at 3 AM

Nile: I keep losing all my items Also Nile: throws gloves and goggles agressively around the lab

I really enjoy the backyard science feel of NileBlue with its different perspective filming where nilered I get that Lab professor who films alone

I think the temperature of the metal when you actually pour it could be making a large difference. it could be allowing a stronger leidenfrost effect to occur (or potentially too strong) meaning the water doesnt touch the metal until it hits the bottom and cools off a bit.

Hypothesis: nilered and Nileblue are not the same person, but instead twins

NileBlue makes me feel like he learned all this yesterday. NileRed makes me feel like he’s the only professional in the subject.

I love NileRed’s slammy nature lol I wouldn’t want to *experience* it, cause I’m too easily startled/sensitive to that kind of chaos energy, but boy is it enjoyable to watch from afar hahah

7:42 and there's crAhcks in it The perfect voice crack

As a chemistry student, this is the most accurate depiction of chemistry I've ever seen.

15:01 - Those are the impurities in the metals, when melting down any metals, the stuff that's not metal burns up and floats. It's usually skimmed off to keep the pour as pure as possible, usually if your making ingots or pouring a mold of some kind.

Great video! Pyrometallurgy is my favorite. I "grained" precious metals for a few years on a large scale and the constant explosions were hard to deal with. Our solution to calm it down a little bit was to get our water moving with pressure washers / high pressure inlet-outlet lines, and to have the water VERY cold. We played around with different alloy mixes as well, but didn't ever have any solid results. As far as why it happened to us, we assumed it had something to do with the copper content of the alloy, the amount of slag and impurities in our materials, and the Leidenfrost effect creating those steam pockets beneath the solidifying metal. We once poured a little too quickly and launched a stainless steel tank with 150 gallons of water well over a foot off the concrete!

I love how on the First channel he's like "I'm not recording and continuing until I get this specific gloves to protect me from specifically this and I'll not use my crucible and Heater if theres a single deformation or weird color". but in here hes like "Yo Fam this Fucking Heater could explode if i use it 40.2873 seconds specifically and My gloves are now flammable because of the acid on it, anyways, let's Add Molten Metal on gunpowder."

Perfectly emotionless voice : "That's infuriating"

14:05 man i genuinely thought that was just nigel but edited in again for a second

2:24 "It's only worth it if you capture it on film." In this case I completely agree. People take a statement like that to heart and think they have to film absolutely everything.

Nilered: "science is serious" Nileblue: "haha glass go crackle"

NileBlue: Messing Around NileRed: Scientific Messing Around

I love how his friend asked if the plexiglass would protect them from the metal and Nilered just avoided answering the question

3:32 [regarding shards of glass and molten metal flying at them] “Actually- I really hope it will. That would make good content!” Camera guy, with trembling voice: “haha yea”

This is kinda scary, they’re like teenage boys playing with lighters but instead they’re chemists playing with molten metal😂

One perk of having awful memory is that youtube tells me I've seen this before and I vaguely remember it, but for the most part I get to watch this video again like it's the first time I've seen it.

NileRed and NileBlue are like 2 different people, Red feels like he knows exactly what hes doing at all times, Blue is like he is just trying this for the first time and going with the flow

I love that I can tell immediately that that fire extinguisher has been recharged multiple times. I'm a technician, and I can see those service labels a mile away. I don't love that the lab has lower quality extinguishers... you figure if you had nile in your lab, you'd spend the extra dollar to get top end cylinders hahah

16:36 "It's not *that bad* ." "We can glue it back together." *crash in the distance* "Oh no!" Modern Day Scientists, everyone

After countless NileRed videos, I was convinced he was a genius robot. Seeing such a down to earth sense of humor is absolutely awesome

Love how Nile is just explaining everything and the peeps in the background just agreeing with everything he says like:”Yea…, mhm, yes!, alright, Ooooh right, I guess so” xD

As a metalsmith/jeweler, next time just use the torch to melt the metal and toss in a bit of boric acid to combat oxidation, actually coat a small crucible with boric acid (pour in a little powder and melt it with the torch to make a glassy coating) then you can melt the metal with the torch but always add a bit of extra boric acid, and they make special stir rods for stirring the molten metal. Yes, the glass exploded due to thermal shock. It's not lab grade glassware and isn't heat safe. Always wear long heavy sleeves and preferably leather or thick suede (NOT MICROSUEDE) closed toe shoes when handling molten metal. Standard mesh athletic shoes will melt like butter under molten copper or brass and you don't want to lose a toe! Y'all should be glad you couldn't see my face during this video...

The crucibles you are currently using are good for silver, gold and aluminum. Copper likes to eat through the crucibles you are currently using. If you plan to melt any other metals like copper or iron you need to use graphite clay crucibles. You should constantly check on the copper because. The longer you leave it exposed to the high heat the higher chance you have all your metal oxidizing. You should use copper or aluminum instead of the tin. Because they're melting temperature is much higher than the tin’s.

when girls say they are into the nerdy guys, this is what they mean

“i don’t mind. you heal. you recover. you are not the asset we must protect. youll recover. i’m- i’m sure you’ll recover. you’ll be fine i’m sure.” 4:11

Lol, I like how the fact that at 20:16 the entire glass jumps a little before breaking. Like you got goose bumps.

Nile: buys gold dust and areo gel and silver Also nile: omg 20 dollar jar too expensive

"we can glue it back together" **EAR-SPLITTING SHATTER** "oh noooo"

Hello, metal worker for 25 years here. The explosion actually has to do with the refractive index of both the molten metal and the glass, when touch metal kasploodge!

I enjoy seeing the safety measures taken to protect yourselves. It’s comforting. Kinda.

Nigel: Where is my glove? I constantly lose everything Also Nigel: *yeets the glove*

Out of all the years I’ve been watching this guy, this is the first time I’ve ever seen him smile, laugh, talk to someone other than the camera, and joke around with his buddies. Truly mind blown

14:21 the top layer you see is likely Flux, which happens often when you combine metals. Just impurities

Nile: “The goal is for a disaster to happen” Universe: “Aight bet”

NileRed: safety first people! NileBlue: haha tin go ooof with blowtorch, deliberately breaks glass, throws molten metal to hand

Awesome video man! I think your completely right about the height and velocity making the difference. I believe that was definitely a proof of hypothesis. Only repeat experiments would solidify it. I think the velocity plays a key factor in when it explodes. When molten metal is submerged in water it vaporizes it instantly creating a chamber of water vapor around the molten metal. (Reference: leidenfrost effect) With the leidenfrost effect comes a pressure differential. When this pressure differential is contained...(by surrounding water) well then the pressure will continue to build until something gives. Water is incompressible so the molten metal implodes and breaks from a lump into crumbs that cool much faster and stop the leidenfrost effect, almost instantly, and then transferring all of the energy, built by pressure, back into the incompressable water only to meet the strength of the container it's in. This, of course, being the glass jar it was in. The energy has to go somewhere and you figured out how to time it just right to make it detonate at the bottom of the jar and blow it up. You ARE a mad scientist. Lol

My favourite part of this is: "We can glue it back together" *Smashing Sound* "Oh No"

This guy's age is a mystery. He looks like he belongs in a high school but at the same time he looks too old to be twenty. And his voice sounds like he's in his 20's.

I love how when the crucible fails Nile just goes "that's infuriating" in the most nonchalant tone possible

Really like your videos on both of your Channel Nile! This videos reminds me of the experiment where you hold a test tube filled with boiling wax into water. Our Students (and we as teachers) love this simple but effective experiment. You probably already know about that experiment. It is entertaining, but I havent seen your take on it (maybe I need to check more videos of yours! :X) I'm looking forward for your next videos and keep up the good work! Greetings from germany! 😄

Nigel, You got such a great smile! it’s a pleasure watching you do your stuff..

Nileblue's casual videos are honestly just as entertaining as your more professional ones one Nilered!

Red sounds like he was discoverer of everything he does on his channel. Blue just read one manual from the first page of google

You might also want to measure the temp right before pouring it in. That is a variable that can be harder to control, but will have a lot do with the explosion

nileblue is what I fall asleep to. Pure chaos to start the next day right.

Nile: why do I keep losing things? Also Nile: *throws everything*

"I swear, if this falls over... I guess I'd just have to fix it again."

I think it’s nice they always have so much fun making videos together.

Hey that was a great video, it was cool to just see you having fun in the lab yet still doing science!

Last Video: Chemistry is Dangerous This Video:

“I constantly lose everything” 12:51 *just throws the glove somewhere on the floor*

NileBlue is me and my best buddy when we were kids in outback Australia discovering the fun that came from his dad's blow torch and metals

Other variables: How high you poured it from. Maybe pouring from higher gives it more velocity, allowing it to get the bottom faster. Maybe pouring from lower gives it less time to cool, allowing to remain hotter for longer (potentially maintaining the bubble for longer, before it cools enough to collapse, allowing water to touch the metal and explode). Maybe small differences in temperature make a big difference. Maybe higher heat maintains the bubble for longer, allowing it to get further down before exploding. Also, gold is denser than tin and has around half the specific heat (meaning it takes about twice as much thermal energy for gold to reach the same heat, ie., gold has much more thermal energy at the same temperature as tin), so maybe the gold worked better because it took longer to cool sufficiently for the bubble to collapse , which gave it more time to reach the bottom. (Also, when the water _does_ touch the gold, there's still significantly more energy to transfer, in theory producing a more violent result.) Those are my thoughts. Nice experiment and good video!

"So what's the game plan?" "Fail like the last time, except intentionally, minus deleting the footage."

"We can glue it back together" *SMASH*

NileRed: Professional Chemist NileBlue: Silly Gewse

Where have you been all my life? I am in love with this entire team making these masterpieces 🔥🔥🔥

"Are we aborting missing?" "Nah, the mission is still good..." This is how most disaster movies start.

I hate how casually and precisely he destroys the crucible with the hammer
