Flashlight vs FROZEN MERCURY (Hg)
Vložit
- čas přidán 10. 12. 2014
- We put flashlights in both water and the liquid metal, mercury, to see which will freeze solid first. Water must get down to 0 C, and mercury, 40C to freeze. The results MIGHT surprise you! (of course there will be some people who KNEW what would happen!)
I need to borrow their crystal balls some time!
If you are interested in buying one of these flashlights, they can be bought at Amazon. They are great flashlights!

Special thanks for Mattv2099 for setting me up with the flashlights.
Matt has a lot more clout than I do!
Matt posted a cool video where he shot some of these out of a shotgun!

Pretty neat!
DemolitionRanch Thanks Matt!
Most excellent science. That's really cool watching the water vs mercury freeze.
Those flashlights will operate in a frozen mercury operation...Good to know...But you probably won't...Bummer dude...
GrOuNdZeRo7777 LOL. how about freezing a bug in mercury?????? like a black widow?
how about "BUG FIGHTS" on mercury!!! bug fights are huge in Japan. they have crazy japanese commentary as bugs do battle in a tiny arena. now make the floor of the arena MERCURY
***** 50 billion view video
Thanks Matt, and thanks again for hooking me up with Thrunite!
Matt shoots these FLASHLIGHTS from a SHOTGUN!

Haha, I was just about to comment that you guys ought to shoot them from a shotgun. Slick.
lol I remember when I subbed that you had about ~3000k subscribers. Awesome watching the channel grow!
Richard Forney when did he have 3 million subscribers??
michael johnson I think he meant 3k, smartass. No need to rub it in
You also forgot to mention about the specific latent heats to change state, water has higher latent heat, so it needs to give out even more energy than Mercury to change state and solidify :)
Do this with a fleshlight, then see if it still works.
a fleshlight? OH GOD i don't want to know what that is!
i made the mistake of looking it up -_-
Hahaha fuck that!.
SuperCanadianMooseRider
do or dont look up blue waffle. u've been warned :D
SuperCanadianMooseRider no you're going to buy one, I bet lol
Awesome!! Really cool seeing the mercury freeze! Liked as always! :)
***** Thank you!!
Gotta say I'm still happy with my Archer 1A I've had in my EDC for the past year. Thrunite really makes quality lights.
Great video. Frozen Mercury looks awesome!
I have a suggestion. It's for the shotgun rounds. Have you thought of doing frozen fruits as ammo?
Like either frozen raspberries or blueberries, anything that could be small enough. they could either be frozen by liquid nitrogen or just stick em in a freezer and pop em in a shell.
Think that would work? Because frozen fruit gets incredibly hard, I think that would be interesting.
We've tried to shoot light stuff like that before and they didn't work very well, too light and they did not allow the main powder charge to go off.
Really? I guess I could see that. You would need something more dense. Well, what about if you took something like a potato or a dense root like Yuca and cut and shaped rounds out of it and froze it?
Not like pre-boiling the potato or anything, just raw.
Marth potato isn't dense too
Marth Any organic material that hasn't been dehydrated is largely water, so as a shotgun round, they're practically interchangeable with water. I think you are conflating density with hardness.
What about an egg or something? Does an egg fit in a shotgun? I don't really know the size of a shotgun barrel.
_very interesting and well presented._ *_thumbs up_*
Why are Mercury videos so addictive?!
-How about we use mercury?
-What for?
-Cause it's MERCURY!!!! Liquid metal! How red is that!!!!
After much deliberation, I bought the 1050 lumen Thrunite TN12 2014 for my bedside flashlight. It is ridiculously bright and well built. Cannot recommend it enough!
Ever put dry ice and a little warm water in a pop bottle and put the cap on?
Pro-tip: Run.
MicrowaveMeShow I usually opt for the least deadly shrapnel lol
then you wonder why they have a age limit now on who can buy them. because people do dumb shit like that.
Why do you hate science bro?
brandonhughes7 science isn't about why, it's about why not!
BSFilms1997 if life hands you lemons... don't make lemonade! *GET MAD!*
I'm very impressed by those. Tuff little flashlight's.
RDFStudios Thanks! We hope to see how tough they are in other videos too!
Nice flash light, and a cool test of durability!
Paul Roberts thanks Paul!
I have their TiS flashlights. It is the same size, but only has one brightness setting. I did not need the modes. I can not see the TiS anymore except old stock so I guess this model is the replacement. I have had it for years with no problems. It works great, and seems very durable.
The main reason why mercury freezes faster than water is its heat capacity which is around 30 times lower than water.
SentiBM specific heat, heat capacity,... same thing. hehe
I once dropped a testube of Mercury in science class in high school - it flowed between the floorboards in the classroom! I do not remember what became of it or if anyone knew it happened - was a long time ago...
Frozen Mercury looks like what Starwars called Carbonite when Han Solo was frozen in it.
I've used the first generation of that flashlight (in the video appears to be 3rd gen) for a few years as a keychain light and it's great! The brightest mode might not last that long but if you only need to use it to get something from under a seat or whatever it definitely gets the job done.
For an AAA battery, 30 minutes is impressive. I have a Pelican that takes two 123a's that doesn't last much longer than that and the lumen rating isn't much better.
***** Absolutely. For all the time i've had mine I have only needed to replace the battery once.
I think many flashlight companies are hesitant to add modes that drain the smaller batteries quickly but the extra light is great when you need it.
My science teacher showed your video to our class! Your so cool
Justin Isa Nice! Which video??
Now get in touch with your English teacher. :-)
The salt and mercury one :)
Awesome video man!
Scott Sherman thank you Scott!
Also has to do with the latent heat of fusion! Heat has to be added and taken away to simply change states!
Pretty cool
fairly obvious, mercury conducts heat considerably better than water. Water has to disseminate the temperature differential through convection (relatively inefficient) and conduction (also relatively inefficient in water) where as the mercury being a good conductor drops in temperature throughout
Mercury is actually a poor conductor of heat
I know quite a few fire fighters that wear these little flashlights on their helmets so they can see in a fire. So long as they don't get in hot enough areas to melt their face shield the flashlights work great and last about half an hour even in that heat.
very kool test !!!
thanks!!
I did enjoy it. This looks like a perfect pocket or purse flash light.
James King Thanks James! It is so small I've almost lost it in my pocket!
that fly is gonna spawn some terminator babies
creative and neat. thank you.
The difference in melting/freezing times would have more to do with the difference in latent heat than specific heat capacity or conductivity.
Chris Fotheringham Latent heat is just the "hidden" heat, the BTU's (calories) needed to transform a liquid to a solid, liquid to gas. That is specific to each material too.
I have to get one of these flashligts! I had the thrunite Ti2 but I was disapointed with it: It worked perfectly for two months and then it started to loose its brightness. Two weeks later it lost its first light setting and the next month it wouldn't light up. I'm talking about less than ten battery cycles. I hope the Ti3 is better.
Awesome as usual :)
***** Thank you!!
not sure how you would contain it but i wonder how frozen mercury brakes? if it shatters like glass? or stays strong like a metal? nice flashlight for sure!!
49erdigging It's pretty soft and flexible actually... I'd say it is very comparable to lead.
This is the best flashlight advertisement ever.
Etherwinter thanks!
What do you do with the contaminated water/objects? Because obviously you can not throw them down the drain or in the garbage.
Wow, that is one tough flashlight!
love watching the mercury thaw out
Those flashlights are aluminum did the anodizing and temp prevent the corrosion.
I thought Oh it must be because mercury is more conductive of heat! Then when he mentioned specific heat, I thought, What the hell?! How did I forget that when it was on the chem final i took just 2 and a half hours ago?!
I cannot decide if Demolition Ranch video or your video is better but gosh dang it ***** you are my favorite channel of all channels
Dakota Kunkle I think DemoMatt's are better. lol I can't sing! Thanks for the nice words!
So the water must release 4.179 J of energy for every g of water for every degree C
While the Hg takes only 0.140 J
Lets say room temp on the video is 25C
We will also estimate the containers to hold 250ml
Water = 1g/ml ( 1g * 250 ml ) = 250g of water
Hg = 13.6g/ml ( 13.6 g * 250ml ) = 3400g of Hg
Water freezes at 0C so ( 0C - 25C ) = -25C or a change of 25C
Hg freezes at -39C so ( -39C - 25C) = -64C or a change of 64C
Plugging into our formula
Water = ( 4.179J * 250g * 25C) = 26,100 J
Hg = ( 0.140 J * 3400g * 64C ) = 30,464 J
The Water should in theory should have froze first according to my calculation ( which I believe to be correct ) as it needs less energy removed.
Any ideas?
My only thought is that the mercury may have still not have been frozen all the way through and only the outer surfaces may have been frozen. Or that both substance did not start out at the same temperature.
what do you expect from someone who spills mercury all over the place? i bet he poured that water down the sink.
You should do a Xmas special!!! Shoot wax slugs at nutcrackers, ornaments, light a tree on fire an blowup a gingerbread house!
This is very usefull test. If I ever get submerged in frozen mercury while holding my flashlight, at least I know my flashlight is still working.
How does mercury freeze. If you have it running down a slope, does it just change state ala presto or does the viscosity of the liquid change before freezing?
Good lord. I read that as "Fleshlight vs FROZEN MERCURY". I need help.
Do the triple point of mercury. I seen it with liquid nitrogen and it would be very interesting to see how a liquid metal behaves when at its triple point.
Hey Taofladermaus, I've been wanting to ask you this. Recently I saw a funny sketch of someone shooting a bullet at the blade of a knife and killing two people in result of the bullet being split into 2 halves. Do you think you could make an experiment video on if it's possible to shoot a bullet at a knife and make it split into 2?
So.. I'm watching this show called "Drain the ocean" on Nat Geo... And now I know what the hell Fledermaus is.
Surprising!
Great video, I am glad you saw the light.... LOL
poboyspecial thanks!!
Why do people say things like "the temperature of dry ice is -109 degrees fahrenheit". It can easily be WAY colder than that. Kinda like why, if you buy bagged ice, it's good to know the people selling it don't just keep it at a few degrees below it's freezing temperature. LIQUID states OTOH are a whole different thing because (in most cases) at STP they will always be bracketed by temperatures at which they become frozen or boil. But solids can in theory go all the way down to near 0 Kelvin and gasses in theory hot enough to cause destruction of the component molecules.
i I have three of those lights they're awesome
how do you deal with the contaminated water and flashlight after?
Impressive. I would love to see a "normal" flash light tested this way as a control. AnywHays, keep up the awesome videos.
Randomguy What is a normal flashlight?
One that can easily found at a non-specialized big box store. So basically a Walmart, Target, Dollar Tree. ect. check out line special. Basically the el cheapos.
Interesting....does the same apply to boiling them? Their boiling points are fairly close as well.
Can you go into more detail about the cleanup? Doesn't the syringe have bits of mercury in it? Your little tub? What about water mixed into the mercury?
Even more funny is, warm water freezes faster than cold ( straight from tap) water
Will mercury conduct electricity?
Imur Huckleberry Yes, very well!
Hi, I have a sugguestion (You already did one, the glowstick/blender one)
You should show mercury (Hg) and the reaction it has with Sulphur (S)
You could also keep some sulphur around when you are doing these videos, as a safety measure.
As chemists call it "The Canary in the Coal Mine" in terms of Mercury safety.
He most likely reuses the mercury and doesn't have the right equipment to change it back and would be stuck with mercury sulfide.plus his channel isn't really much about chemistry
Stopping at 1:27 to say Mercury first. Even though Mercury has the lower freezing temp I remember you saying in an earlier video that Mercury is an excellent conductor of heat. This should mean that it will absorb and transfer any latent heat above the temp of the dry ice very quickly, perhaps faster than the water.
Would mercury go through a strainer? Or is it too dense
That mercury-flashlight has a bit of a Han-frozen-in-carbonite-feel. Maybe you should try that on a Han Solo action figure?
64bittinen haha, I thought the same thing.
I gotta say thats wicked
Hey if you get out with the shotgun again soon could you bring some nails (as in those you use when nailing two planks together, JFC) of varying sizes, i think you can stack them so that half of them point upwards while the rest points downwards to maximize the effect?
(and maybe bring one of those flashlights too)
Official store link doesn't work anymore.
And good news! They're only $13.95 on Amazon now!!!
Nice! Although, do the flashlights have replaceable LEDs? If not, they will only last as long as the LEDs, which will eventually get dimmer over time.
Matt Rouge They are rated for 20k hours. I've never heard of anyone replacing LED's in a flashlight before.
Awesome video! I thought you didn't get any from them, from what ya said on MattV's channel. Lol well I'm glad they felt bad and sent ya some! Love these videos, can't get enough man.
Just saw your comment... Lol
JBTactical The company emailed me in early November asking if I wanted some flashlights and I told them I did, gave them my address and all that but they said they never got my email. Then Matt contacted them and said i tried to contact them so they got in touch with me again. It was a cluster-f . lol
I payed $50 for a 1000 lumen flashlight. Granted it uses 9 AA's but it has a battery life of 3 hours at 1000 lumens and likely much more at its red and blood tracker settings. I use it as a lamp sometimes because its so dang bright it can light up a room just off the reflection from the ceiling.
Make Mercury (II) Thiocyanate Hg(SCN)2. DO THIS IN A FUME HOOD.
Is it possible to decontaminate that flashlight or is it impossible and how would you go about doing it
why did the flashlight turn grey?
Never seen solid Hg before. cool
Does the mercury not get dirty? Do you have to skim the top off every once in awhile from residue and dust and such mixing in, from it being open to the air and going on things like the flashlight that you had presumably handled and gotten skin oils on and such? Or does it just not pick up things like that?
It gets a little dust on it.
***** How do you clean that off? Or is it not enough to be an issue? O:
I usually just draw the clean mercury from the clean bottom to bypass the dust on the top.
The song kept me here...:-)
Guys what is your best comeback to "you dimwit"
Steve Pfister I don't know but I think you've been watching too much 1950's-era television!
+Steve Pfister really late response but
"Sorry, im not a dimwit, im actually a brightwit." then i'd throw one of the flashlights in this video at the person who called me a dimwit
Deez nuts ultimate comeback for every thing
+LYNX 06 *For a 6 year old
+Steve Pfister I believe the correct response is, and I quote
"if you want some, get some, bad enough, take some
But watch the gun by my side
Because it represents me and the motherfuckin' East Side
So bow down to the bow wow, cause bow wow
Yippie yo, you can't see my flow"
1:56 is when i noticed this stuff was on a giant freaking block of dry ice. jesus christ!
Bas J It wasn't THAT big, it was just that the flashlights were very small.
Is there mercury in the water now? Do you have to dispose of it properly?
Toafladermaus, I would like to see a pop it's shotgun round. Love the vids. 😃
Skeetshooting7 I'm certain they are too light to ignite the main powder charge.
Would submerging the tin boxes beneath the dry ice make a difference in the freezing speed?
Erwin Chiu Maybe a little bit, but they were sinking into the dry ice as time went on.

IT KNOWS.
Awesome. I love these videos. I do really want one of those thrunite lights though. It would have been really cool if the aluminum case it came it amalgamated.
x9x9x9x9x9 I'm not sure if these are painted or anodized... you need perfectly clean alum. for the amalgamation to happen.
How do you dispose of it
Alert! Watching mercury videos can result in Mercury Poisoning. DANGER!!
Elemental mercury isn't very toxic like people believe
I believe, it is due to mercury being a liquid metal at room temperature. Mercury has a lot more free moving electrons relative to water, thus very effective at conducting heat.
Awesome.
EPaR - Aidan Gieg thank you Aidan!
***** You're welcome! Also I accidentally blew up my beaker with sodium... XD
Oh no! Be careful with glassware!
***** Yeah, it was funny. I was recording a video of, it and I used it in my channel trailer.
Can you please do A video with you putting a Alka-seltzer pill in Mercury.
It won't dissolve in mercury if that's what you're wondering
I still prefer a pushbutton switch on the end of a flashlight rather than a twist switch for easy one-handed operation. And the flashlight has to be long enough to fit in the palm with both ends sticking out just a little for comfortable operation.
The switches are often the Achilles heal of flashlights. All the techs at work got a Pelican M6 and most of them broke from a short, 3 foot drop on the switch end. Sure they will replace the flashlights but that's a hassle. These little Thrunites are as bright as the Pelican M6's. I don't like the hassle of twisting them (two or three times to get to the setting you want) but I don't have anything else bad to say about them.
Oh geez, they got Han Solo's flashlight too, those empire bastards!
where do you get the Hg?
uploaded 12 minutes ago :O that's the quickest i have ever made it to a video :)
(yes it is wrong there are comments from 40 minutes ago) i will take my victories when i can get them!
***** My identical clone typed that message
That was cool
Matthew Acaldo thanks Matt!
I know you don't want to loose your mercury but i was wondering if you would light it on fire? It's supposed to cause a very cool chemical reaction!
MrLegodude159 It isn't flammable.
I thought it was? Maybe I'm thinking of something else.
@@TeaAndBullets try caesium
How in the world do you dispose of the things you put in mercury?
10Greylock I just use a clean up powder specifically for mercury spills.
"No one likes long intro" -TAOFLEDERMAUS
Im a little curious about frozen mercury, i know it is very dense for a liquid but how does it compare to other metals when frozen?
Its really similar to tin
shot the 22cal pellet with the smallest nail gun charches
you should have left the flashlights on when you froze them
TheSoradam They were on.
saw cutlerylover's review.... these are super tough lights
I'm proud of myself for predicting the effect of specific head capacity and conductivity. Go me! Of course, I have no way to prove it....
now do the batteries still work i am more intreasted.
