Car tires vs. our 300 bar / 4000 psi high pressure air compressor on dry land and under water. How much pressure can the tires take before explosion? Don't try this at home!
You should do a series of freezing water experiments. Eg. Large balloon filled with water. Or spraying water and watching it freeze before it touches the ground. Or growing icicles.
If my calculations are correct they are imprecise, but according to them 30 liters of air in 60-70 bars holds at least the amount of energy of several dozens of kilograms of tnt, or dynamite. Be very careful
@@sairassiili If the tire was such a large boom, the tank will be a lot larger. Be mindful of shrapnel and stuff - best dig in and make a foxhole for that. Blood spraying out of either of you in slow motion would not be cool. Other than that, I am looking forward to this! :-)
Does it make any difference that he didn't say professional right at all? Lol I love their accent though I find myself talking like them after binge watching the channel sometimes!
♥♥♥ I love you two! Lauri, with your wild ideas and genuine fascination about the results of your pressing and other stunts, and Anni with your excitement and laughter and your beautiful smiles. May you both be blessed with great fortune and health. You are my favorite couple. Big hugs, and lots of love and admiration from Pennsylvania USA. ♥♥♥
Once when I was in denmark a truck tire exploded!! That was one hell of an explosion. It was really loud although I was in my car. So if you like, try an old truck tire! Truck tire! Truck tire!
Yeah they are normally filled with more air pressure, and designed to carry more weight, so yeah they can be pretty damn loud. Ever seen the video of the guy who tried to slash a truck tire? He died instantly. His clothes were ripped off, and skin peeled back a bit too! (Similar to the damage from a hydraulic hose/pipe failure.)
A month ago my left front tire exploded on my truck, I had the window open, it was pretty loud ;-) Flew parts on to the parking lot at a house I just passed. Now I got two new wheels, don't want to do that again ;-) So my suggestion is, truck tire, truck tire, truck tire!! :-) :-)
You could attach a hydraulic line to the tank that comes to the surface so no valves or connections to go loose. Also I would like to see one tank under the ice and another tank INSIDE ice!
+superdau Not if the valve is beneath the surface. Lakes do not freeze all the way to the bottom, only from the very top. The rest is something like 1-4 celsius through winter. So totally viable and better way.
Underwater slomo footage is amazing: the explosion releases a huge air bubble, pushing water away, and then the lake strikes back and evacuates the bubble. Great shot !
I knew the tire explosion idea was going to be pretty decent,I recommended this idea in a earlier video. Lauri/Annie,I was most impressed with the underwater tire explosion,it took that heavy rock and threw it a few feet into the air!!.WICKED!!. Now this winter's air tank explosion will be super wicked without a doubt!!.
Nice! I wanted to suggest in the comments that you should put a tire underwater and explode it there. I was shocked that you did it in the second part. I'll wait for the under-ice video. Greetings from Russia!
That underwater shot murdered your camera didn't it? :D Perfect example of the incompressibility of water and how a depth charge can sink a submarine without a direct hit being needed.
Nice explosions. Good idea about steel tank in frozen lake. Anni gets lots of bonus points for helping with this one! My wife and daughter would be in the house somewhere not being any part of this kind of thing!
@@nothingsurprisesmeanymore Yes, it seems to be the nature of RU-vid channels that you have to keep getting more extreme as time goes on to keep people interested.
So cool! I am an automotive mechanic and I often see vehicles come in with tires inflated to 5 or 6 bar. For a standard car tire that's way too much and I always wondered; How much until one of these goes over a bump and BANG! Good to see this video because now I know that it takes a LOT of pressure to blow up.
The air in the tire is both hot and humid, but when it expands it rapidly cools and drops all the moisture contained out, that’s why it looks that way, extreme temperature variation and water vapor
Some person I heard of built a tire filling compressor from an old fridge compressor, and used it to fill a huge tractor tire, and because it takes a long time to fill, he simply left it running and forgot all about it. When he finally remembered it, the tractor tire had reach a ridiculous level of overpressure, which of course made it a lethal explosive device. All the guys in the village gathered around it (at a safe distance) trying to figure out a way to deflate it without risking death, and eventually the only way they could think of was to shoot it from a distance with a .308 Winchester, which certainly did what was required, deflating it and rendering it safe to approach.
Haha, two words "money shot". Overall Anni`s SFX 🌲/viisi. Also you could try to explode forklift tire, those are supposed to be inflated to 10bars in normal use!
There are three great things about HPC videos: (1) Anni's reaction to the explosions (2) Whatever scientific stuff is happening, but that is not as important as (1). (3) NELLI!!
I've always wanted to see a car tire exploded this way. I worked in a tire shop and those compressors were regulated to about 11 bars, enough to blow up a weakened tire such as one driven flat too far. These were hilarious to explode because they form ominous multiple bulges and make really funny rubber stretching noises. They only took 3-5 bars to explode. Try it sometime!
Robert Chandler Also fun is disassembling struts without a spring compressor. Wrap the spring on the strut in a towel and set it on the floor. Safety first lol. A smooth concrete floor. Sit down with your legs out, place your feet on the strut bearing. Take your airgun and reach between your feet and remove the strut nut. Vw mk1 struts slide across the floor about 20’ (6.5 meters for my metric friends) Met Rick? Yea he’s a good guy 🤣🤣
Aircraft tires are very high pressure, usually 150-200 PSI for airliners as I recall. That should break some windows when the SOB goes off! Don't try that without ear protection, even if it's underwater!
It would be the closest thing to a Daisy Cutter or MOAB (graphically of course) in the finnish forest unless there is some safety feature (valve) so get Nelli well protected also.
@@floobertuber beyond 200psi. There have been deaths from overinflating aircraft tyres. www.boeing.com/commercial/aeromagazine/aero_05/textonly/m03txt.html
HAHAHAHA Money Shot.... Love Anni! You need to put a tire in the water with the hoses floating so you can get them when the lake freezes and then you can explode it! Lauri is so much fun to watch and listen to when things happen, just like a big kid! I would feel the same way!
Won’t need a fire. The propane and oxygen from the air will detonate because the incoming air will cause a temperature rise because the gas is being compressed. I suspect it will spontaneously explode!
@@Beyondthepress That sounds awesome. And I agree with NoisyPlaces there is a good chance of it detonating due to heat+air+propane alone but I don't know if it would do it for certain. If you do it maybe you could explore if a fire is needed and we could get a side of science with our explosions. Another idea is testing aluminium vs steel cylinders or different flammable gases. Maybe even using pure oxygen too. Anyway looking forward to the air cylinder in the lake and the propane tank shooting.
The visible "Schlieren" in the air after the explosion came probably from the difference in the density of the compressed air inside the tire compared to the outside air pressure, a shockwave so to say and also the compressed air was certainly warmer too, kinda heat shimmering.
That was a great video guys, thoroughly enjoyed both tyres going boom! The rock shot just showed how much force was involved in the explosion. Definitly got to see the frozen lake idea ;)
That camera is really good on high frame rates. It need about 2-3 times less light than color one so it's perfect as an faster camera with slower running color camera
@@Beyondthepress I really struggled with that question when I bought mine. In the end I wanted the nicer looking image in color over the more sensitive sensor. Every time I see your shots though, knowing RU-vid butchers the quality, I question my decision! I really like seeing footage out of both cameras. Keep up the great work.
