huh. glowsticks self-activate once you get below the sunlight zone. neat! :D

definitely one of the better science channels to come out this year

The actual pressure section of the video is so dramatic, feels like something from a movie or something lol. Like watching the glowsticks start to break as a sub is leaking water under the ocean.

Dropping glow in the darks into an ocean trench sounds like a better plan than using your car.

As soon as i saw the glowsticks I knew this would be good

Really entertaining and what's even better is that you usually learn something in the process. Apart from that, after all the interesting things that have already been in the chamber (polystyrene cups, eggs, glow sticks etc.) I would be interested to see how a piece of normal wood behaves. So a lightwood type like balsa, a softwood type like pine or fir and a hardwood type like beech or oak.

I love how the ampule cracking gets more and more violent the higher the pressure. I was secretly hoping to see them start splitting open and spraying everywhere. But I knew it was doubtful because of their construction. Those things are next to indestructible to everything except slicing/piercing.

I feel like a channel that does experiments like this deserves more attention and subscribers. More people may watch and like the video more with background music added, even if its very very quiet compared to speech.

Who needs glow sticks for a deep sea rave when all you need is camerons sub and a bunch of angler fish and those pulsating light creatures.

The algorithm really surprised me with this one. Im excited for what other ideas this channel explores!

So cool how the glowsticks flew around.

How does this channel not have more views/subscribes?

We used them in our shot line projeciles back in the day. A Cyalume rep came aboard and saw the trouble we were having with battery powered liights when we shot messengers to the ships that came along side.

I started watching this channel at around 1k subs. Now at 8.67k subs I feel this channel is still criminally undersubbed. Great content.

This is pretty fascinating, why they seem to go at different times, like popcorn

@13:33 - Bro, you made me spit tea out of my mouth. "It's The Asian Way" I didn't realize that you have a wicked sense of humor tinged with a dry delivery. Very nice combination. Like Dr. Grande!

I am reminded of one of the closing scenes in "The Aybss" where the main character has to activate a giant glow stick. I think he was at that point over 15,000 or maybe even 20,000ft using a liquid breathing suit but I could see a oil company being able to afford specialized emergency glow sticks that can survive at those depths and not go off prematurely.

The dichotomy between the wildly over the top duel of fates remix that is far too epic for what's happening on screen and the science content that's way more epic than its monotone delivery is exquisite. (I love the monotone delivery btw, it makes your fantastic wit hit that much harder)

The coming up was way too fast. These poor glow sticks might suffer from decompression illness.

as a really long time viewer im so happy to see you doing cool shit like this keep it up dude!

When I saw the title I remembered I have a bunch of glowsticks in a drawer, turned off the lights and cracked a few and it was actually really cool to watch this video in their ambience!

I get so giddy when your videos pop up in my feed! This is my favorite channel. Keep it up!

That was... illuminating.... ahem...

The midnight rave got me good. Regarding the fun fact, im not sure what triology you are talking about but if you meant the first with the jung Luke and not the green milk drinking one: They used highly reflective screens and wrapped it around tubes, then shined the bright studio lights on them. Practical special effects. So much ingenuity.

Just be sure to bring colors other than plain green, for when Ed Harris needs to know which wire to cut...

Very informative and entertaining! Thanks for the glow stick pressure chamber light show!

Very cool! I so appreciate the scientific explanations combined with the historical background and practical application to how glow sticks have been, and still are used. Great video!

Perfect music.

Another fun Star Wars fact… Any light emitting device , like glowsticks (military “chemlites”) is referred to as a “LUMA” in most of the books. Tablets are “Datapads.” I often throw people with the terminology, and it gets to be quite fun!

First time viewer. Nice one 👍🇦🇺 Was expecting you to be in a boat with miles of fishing line !!!

I know a guy who knows a guy who used glow sticks (“chem lights”) in their mouths to crawl through the intricate tunnel systems during the Vietnam war. Hands had to be free so the on/off switch was opening/closing one’s mouth

5:51 Your fun fact about original Star Wars trilogy and glow sticks is incorrect, they used reflective tape on a spinning rod that’s powered by a motor inside the hilt, the stage lights behind the camera shone its light and the camera picks up the reflectiveness, its also why the lightsaber flickers during the obi wan kenobi fight with Vader on the Death Star From a massive Star Wars fan

Each video is better than the last. Keep up the awesome work.

I would love to see a video about the chamber itself. How its presurized, how you get audio, the thickness of the walls/glass, and so on.

Another nice vid! I've got to admit, that I have been thinking alot about (sports related) balls, ever since the superbowl edition video. It would be cool to see different kinds of balls under pressure, like a golfball and tennisballs etc.

So if I was dropped into an ocean abyss to deactivate a nuclear warhead, a glow stick would be able to provide a light source.

Great, now I want to take a boat across the ocean while throwing glow sticks overboard to mess with deep sea creatures.

Maybe the little glass vials used in fire suppression sprinkler heads? They explode outward when reaching certain temperatures.

@TheDropzoneChannel Thanks for doing the glow sticks. They were awesome i loved them jumping around .Gotta say i thought they would crack and glow then pop and go out with the pressure. Im impressed 👍

Golf ball Ping pong ball Baseball A tick. No one will miss a tick.

Inflation is going up, surprisingly, the only direction it can go.

Now, I want to see a lightsaber fight underwater.

Divers use chem lights all the time to increase their visibility to other divers, and cave divers often use them to mark paths and exits

First thing I thought about was the inconsistency in manufacture if the same brand of stick activated at different depths. Wouldn't matter on the surface but if they had been manufactured to only implode at a specific depth, that would be interesting.

I do love your videos mate. ;)

5:50 not sure which trilogy you are referring to, but the original trilogy didn't use glow sticks, the used poles with reflective tape arranged in a two or three sided configuration and spun the pole with a motor to get the lightsaber effects.

im more amazed at your rig then the glowticks ...thats a level of psi i never knew we could test things at

@0:18 - Wait, aren't you the guy that introduced me to oil filled watches and brilliantly demonstrated that with a pressure chamber. The video where the clicking and cracking of the watch tripped me our so much?? Dude, you have managed to capture my watch time when I have no specific interest in your content. That must be something pretty rare in YT terms. I may even look in to subscribing after I finish this video.

When Duel of the Fates started playing I was like mmmmmmmmmmmmmmh

Funny and brilliant!! 👍😀

I used to use these while longline fishing. We were only in about 400 fathoms at the deepest. (2400 feet) This is most interesting. So, I take “unsnapped” glowsticks, tie a bunch of them to a rock or some weight, and toss them into the ocean where it’s better than 3000 feet deep, and I get to entertain sea creatures down there…. Cool!

Completely impractical but imagine having the entire chamber filled (only 1 layer from the cameras point of view) and them see if the shock of 1 going off sets off a chain reaction for all the rest. Potentially just wrapping a laying around the outside and have say a 3d printed disc or something front and back so its as rigidly connected as possible

Where did you get the idea of the light sabers being glowsticks? In the OT they were spinning wooden dowels with reflective tape on them that produced a glowing effect on camera. In the PT they were basically the same thing using different sturdier materials. In the ST abominations they were made with reinforced electrically lighted rods to have the sabers cast light onto the wielders.

lol that rave would be insane, water carries sound better than air, so the whole place would be as loud as the front row 🎉🔊☠️

This one by far is your best one. YET Who knew if you drop them in the ocean they would light up the sea floor.😮

I would love to see how deep a golf ball would go. Love the Party mode video..

Highly satisfying.

Finally, a scientist asking the right questions. 😄

I was really hoping you would go a step deeper into the electron transport chain and excitation levels. But still very cool.

Glow sticks played a crucial role in the deep dive movie, Cameron's "The Abyss". A diver had to disarm an nuclear weapon at depth--but his yellow-greenish lightstick made it impossible to distinguish the color of the wire he needed to cut! That entire movie hinged on the failure of technologies operating outside their design limits. First three that come to mind: Failure of the hoist cable to detach under stress; seal failure in a submersible (provoking the immortal line, "All I need is a damn Crescent wrench!"); and the mentioned color-coding under emergency lighting. Humans also fail under stress--but a few come through.

I think this is my favorite so far.

I am so glad I subscribe to this channel

This was fun and new for me, very interesting chemist lesson too. They manage much longer then that I thought.

That was pretty cool. I didn't think anything would happen.

lol the intro is giving submersible subliminal something 😜

Inflation doesn't "go up". Prices do.

There's something uniquely appalling and horrifying about considering the depth of the ocean and seeing depth values like 3000, 4000, 4400 meters. That's so staggerinly much water. It's a kind of depth I can't even begin to process. 2¾ MILES, for my fellow Americans who don't want to check the numbers themselves. I live in a small town in Upstate New York nearby to a lake that's just under 300 feet deep (it's not even 90 meters deep) and I can't swim in that lake except for right on the shore. As soon as I can't touch the bottom I start to panic a little lol. Less than 90 meters with no unknown lifeforms to speak of, and it horrifies me. 4400 m is a depth I can't fathom (no pun intended lol.)

I’m surprised there was such a wide range in pressure that they activated.

2:32 careful with the microwave

Now try in a vacuum

I swear the military actually invented everything that we know

Amazed they didn't all rupture.

That glow stick looks like a uranium 253

…and used for practical jokes. I was an Aircraft Weapons Mechanic in the USAF. If it had anything to do with the weapons systems on the aircraft, I did it. During a war game exercise, while wearing full MOP level chem gear (including mask, booties, and gloves) at about 0200 hrs. One of the conditions was simulate blackout conditions. No lights. No flashlight or headlights on vehicles. Duct tape the lights. So for safety purposes we would hang these green glow stick on us. But they have an issue a few hours later. They begin to leak. One of the weapons I got to load was a B-61 bomb. Not an inert bomb. The real deal. We always used the real weapons for these war games. Its about 0300, war games over. Time to download the aircraft, and put the weapons to bed. Using an M-J1 weapons load truck, my crew takes the weapon off the aircraft. Watching us closely from outside the “no lone zone” is a security police. Now, this guy is nervous as a long tailed cat in a room full of rocking chairs. And I can tell. So I decide to have a little fun at his expense. My green glow stick has been leaking pretty good. Good enough I have a big glowing spot on my chest, my hands, and all over the weapon we are transporting to the weapons trailer. Me, the weapon, and the lift truck are dripping green goo. I look at the SP, and say, “My bomb is leaking”. The guy almost fainted. He went ghost white. He fumbled with the mic to his radio trying to call someone. I yelled, “whoa whoa! I’m kidding. Its just a leaking glowstick, see?” And I held it up for inspection. He said, “oh, I figured that after 2 seconds. But I got to call in for relief, I soiled my pants”😢

That ………….was freakin Awesome!!!

Your content is "Subbed For Life" worthy. And everyone knows why.

So I guess we should start making submarines like glowsticks

Great and interesting:-) Maybe you can simulate something even deeper by pressurizing the item before putting in the tank? If possible, add 100 bar to something.

i think the lightsabers were made from a retroreflective tape thingy though, no?

Off topic, but have you thought about doing your own research into what happened to the Titan submersible? We’ve seen the computer simulations and expert analysis. Would your pressure take be able to show what might have happened if a similarly designed and smaller scale model gives a more accurate representation?

OceanGate should have been built with Glow sticks!!!

So rave at the Titantic !

Any idea what the pressure would be at the deepest known shipwreck? The USS Samuel B Roberts lies at 22,621 feet, I was curious what the pressure would be down that far.

It's incredibly difficult to reach the Abyssal Zone, not many people have the equipment, skill and knowledge to beat the MIdnight Zone boss...

The better question is will it keep falling without a weight?

Must be taking advantage of a power outage 😁

Great channe, keep up the great work.

Why are the chemical drawings so cooll looking ;)

I love this channel...Thank you!

Came to watch shit get crushed, stayed for the bitchin tunes

Don't know how I got here, but glad I stayed!

@5:23 - Bro went totally limp in the Twilight Zone. LMAO!

Do they get brighter as the pressure increases? It doesn't look like it in the video, but, the camera could be compensating for the change in luminosity.

Love the videos keep up the good work thank you and I know where to have my next rave🎉😂

*As seen in the A Bomb defusing sequence of the motion picture 'The Abyss'.*

We had infrared glow sticks in the 'storm.

Very cool experiment

May I ask: Is the videos of the Sticks in the take taking the pressure Speed up or is this in 1/1 time or less maybe? If in real time 1/1 speed or not it's just amazing to see the way they mix and how they really have some pop in their force those ones really know how to move fast! Amazing video, I Hope to see more amazing video because you definitely got my SUB N Like! Also at (12:22) at even .25 speed and using (< and >) to look frame by frame, you still do not see anything at all, 1 Billion percent want to see the glass breaking in super slow motion! Also really cool here is you can see the popping or implosion causing the stick to move so fast it pulls the ones below it up some.

This went well

I wondered where you been. Turns out KZfaq cancelled my subscription. This video was cool.
