15:01 Haha, looks like Tori had the PERFECT timing here!
"Sounds like..." BOOM!
Could not have scripted that any better.
RIP Grant, Thank you for the memories!
I totally 💯 percent agree with you and your comment.
What are you talking about
@@JoaoSoares-rs6ec You couldn't possibly be that stupid.
@@JoaoSoares-rs6ecGrant imahara passed away to a brain aneurysm in 2020 sadly 😢
@@kriswhite9324 didn't know that, sadly
Lets take a bit of this science further for a breakdown:
The super soakers tested, except for one, all use air pressure propulsion to eject the water.
So as the water comes out, so does the air, breaking up the stream.
The last one tested, the big red tube, almost uses a hydraulic system to push the water out toward the spout.
So long as the force behind the “trigger” applies smooth force to the system, the water wont break upon ejection.
The more you know 🌠
Its a weird episode. It starts with Adam referencing he was unknowingly got pranked and injured by Keri Grant and Tori with the shocking Arc, and ends with being pranked and injured by Keri Grant and Tori with walking on fire.
It was Kari, Tori and Scotty - Grant appeared later.
@@retrosquadchannel2.050 INDEED! It was in a that old episode. Right!
I would hardly call the coal walking getting pranked. He fully knew what he was getting into and that it involves risk. The "injury" was also entirely overplayed for dramatic effect.
22:22 This bit of comedy had me giggling so hard. Brilliant deadpan by Adam.
12:34 "3 survived, everyone else died in a latest explosion".
You can hear the minecraft dropper sound at 44:53 hahaha
Safty is concern number 5 at best at 12:35
The three are behind a aheild and the camera crew is right beside them outside of the blast shield.
The camera guy standing 5 ft away
Its just funny AF
Camera guys have the most dangerous job. When shit happens you see them run
The charcoal heat test is always a highlight for me in this series. I remember kid me having his mind blown when I saw that.
So much nostalgia ❤
True
Grants and Tory’s friendships always makes me happy you can see it here 15:01
To those who think the build team should've used different sized fires, if any, I'll say this: I've personally whitnessed a fire a fraction of the size they used still burning fiercely in the midst of a thunder downpour with massive amounts of water. Although there had been a long period of draught prior to the downpour, I'd still say that it's not the size of the fire that matters as much as the intensity of the fire in relation to the quantity of whatever type of extinguisher used. So if anything, they should have determined beforehand the efficency of each type of extinguisher i.e. by scaling up the intensity/size of the fire until it no longer could be extinguished with resp. type of extinguisher busting. That way, we'd also learn which type of extinguisher is the most effective. But, as with the Mc.Gyver vs gun-powder filled door lock, it's ultimately the producer's fault if they didn't get the sufficent funding to conduct a scientificly correct experiment.
38:37 Clippy spotted
The explosion at 15:27 isn't the same as the one at 15:23. At 15:27, the wood pile is smaller, and there's no slide frame visible.
Savage wearing his "Am I missing an eyebrow?" T-shirt while doing his firewalk. 😄
LOVE IT!🤩🤗❤MORE EPISODES PLEASE!!😍🥰😘
Love how they forgot to mention that blowing up the fire like this, causes a ton of hot embers flying about. Try that when dealing with a forest fire....
22:27 - " oh okay"
46:52 - and that's literally a proton pack ray
I love the tesla coil experiment. In Germany near München we have similar stuff. The stungun with water is pretty impressive.
SUCH an awesome episode! Laughing my arse off so much throughout. And they could always put a mini Tesla coil on top of a fire truck and squirt a water cannon from it to do riot control 🤭😆🤣
I'm joking! But I can imagine it being in a GTA or Saints Row game 😅
Hmmmm sadly they aren´t in business anymore. Beginnig at 33:40 Adam talks about resistance of mediums. So my question is something I think we all been tought about. That is when you´re swimming in a pool, lake, whatever... and a thunderstorm hits the area you should leave the water immediately. Most people I asked answered because of the probability of the lightning hitting the water, because of it´s bigger surface. The lightning then transfer all it´s electric flow through the water and kills you. Adam said water has a quiet high ressistance. So I asume that air has even higher ressistance. But would be interessting to see if this is true. Or maybe the Voltage decrease after a certain distance, wich could mean you´re safe(r) staying in the water????? Haven´t seen all episodes when I was younger, do they do that or has somebody else an answer to that?
I wouldn't say it is more probable lightning to hit the water because of the big surface. Like it is said in the episode, lightning seaks the shortest distance to the ground. Especially lakes and seas form large flat surfaces where a swimmer or a boat raises above the surface and thus are more likely to get hit by the lightning. Same reason why you shouldn't play golf during lightningstorm. Golf courses are generally quite open areas where a player can end up a great target for a lightning searching for ground. That's why you are generally safer on the ground where there are hills, trees, and tall structures that are more attractive to lightnings.
Why the hell there is a "firewalking institute of research "???
I always wondered would an ultra fine mist work.. like in a green house.. one outlet of mist in positive output, another in negative output.. when they are in a mixture of the mist, hit the voltage
15:01 - best moment.
One factor not mentioned in the firewalking incident is that the Three Mythketeers did theirs after sunset when there's likely to be dew in the grass to coat the foot, and Adam did his in bright sunlight, when just walking barefoot on the warm pavement probably dried his feet off before he even got to the grass which was also dry.
When the coals are that hot, any amount of dew would have made little to no difference.
@@Shakes-Off-Fear Google the Leidenfrost effect. Also check out the episode in which they dip their bare hands in molten lead with only a thin layer of water to protect them.
100% didnt help. but also grabbing coals with your toes isnt a great idea lol.
No, that doesn't make a difference. Firewalking is actually because of human evolution because human bodies are designed for walking. The way we walk distributes force over our entire foot to minimize soreness.
@@scrivener68You just gave the problem with the Leidenfrost effect: it requires a thin layer - i.e. a _complete_ coating for it to work. Dew can only get on the skin in drops, the drops can only be spread so much under the compression of a step, and water is just as likely to come off your foot with each step as it is to get on there (the basis of water footprints).
In short, the Leidenfrost effect does not come into play for firewalking. It comes down to timing and technique, neither of which are of any particular specialty - just a steady pace of regular flat steps with no toe-spreading/clinching that could pick up and hold embers (basically, do not walk the same way Adam did).
Did the Mythbusters use just tap water in their electro-water pistol, or did they add electrolytes? I don't recall it being mentioned and I imagine that would have an effect on the results.
Adam said "salt water" during the demo.
@@benoit7430 Cheers.
I wasn't sure if it was mentioned or not.
46:43 that looks unreal 😮
10:57 never been happier to know there is no safety valve no more
i love whe the narrator is not wispering in mi right ear...
it is mind over matter. Even Tori states right after he walked back that its about whats going on in his head. Its about being over the urge to run through it and force oneselves to walk lightly on it.
21:59 i want that t shirt from adam 😅😅😂
I am sad, as an Electrical Engineer we use 'Dry powder fire extinguishers' as well 'CO2' as moisture reacts badly with live electricity, as Adam & Jamie are doing. Dont mention 'Water Mist extinguishers' as they kill electrical equipment.
why is there a "Firewalking Institute of Research and Education"? that's gotta be the most niche organization i ever heard of
That reference at 2:40
never knew Adam was from Birmingham
maybe not a holster... but what about a vehicle?
you could make a tesla fire truck
3:00. At last! The moment I have been waiting for while watching these episodes! The goddess that is Scottie Chapman!!!!!
Shout out to Allen Pan, among other things at one time the owner of the Mythbusters trademark & maker of a working water-powered stun gun ^^
You realize Adam hates the guys guts, right?
Mythbusters: "water stun gun is busted"
Allen pan: "Let me show you how its done"
The best part about science is that anyone can repeat the experiment, make improvements to the method and even disagree with original author if there is enough justification
"Don't try this at home" is a great phrase to use when not getting sued, but perhaps we should reboot mythbusters with the phrase "come have a go, just be careful"
@@igttgit I agree people increaseing the pressure in their water heaters is a great idea.
If they drop from 50,000 to 5,000 on contact wats the point of having 50k volts and calling it a 50k volt gun wen its only 5,000 volts wen it actualy matters???
would the ballistic gel carry a current the same way a human body would? doesn't the human body have it's own mini current? I get they specified they were uncomfortable testing on people given the history of people being shocked on the show, but was this truly the best replacement medium or just the one easiest to access?
26:25 What on earth is he saying? In England we call these grass rolls "Turf"
sod . In California both terms are used, but "sod" is common for real grass; "turf" has become associated with "astroturf". But both can be used. One big supplier of real grass calls it "turf".
Do you think adam knows these are aired on youtube
who do you think keeps on uploading them??
Interesting thing is, a firefighting grenade has been invented recently... guess that one is confirmed/plausible retrospectively 😂
@@Stupetin wow, didn't know they had been a thing for that long!
@@viktorthebird6115 They were made by a few companies, honestly wish we still had something like it, sadly they were also really bad to human health (for example a lot of them worked by removing oxygen _"over an extended period of time"_ ) which is why they eventually had to stop producing them, but it should be possible to make a 'safe' version today
Sure this is in California ... where else ...
25:56
Back to the roots Cali ... (apes on trees)
Lol Kari wearing dress in workshop
Bruh when the three of them walk on the coals they walk on the opposite side of the red hot coles...and then adam just walks in the middle of red hot coals
Should have tried salt water for the stun gun
They were using salt water adam kinda states it just before the 18min mark
I think if you have tough feet because you are always barefoot, you can take more heat.
😂
44:34 - "Greg's tezzler coil..." - that's right, he pronounced Tesla as "tezzler".
As in Nicolai Tezzler.
46:52 i think this is one of the most dangerous thing they did PERIOD.... That electricity could easy backfire now through the water beam. that cage doesent do a shit when this happens.
I mean, bodies are mostly water anyway, and with a million volts, very conductive regardless of the water stream splashing back. Heck, at this voltage the plastic or rubber gloves don't matter. It'd take 50mm of solid PVC to block a million volts(20kv/mm) As long as they 'keep their hands inside the ride'(faraday cage) there's no circuit to complete so it's fine.
Progressive design? This is just another overengineered crossover with an unreasonable price tag. Make cars that do their job, not try to do things that humans can do much more efficiently.
The coals were twice as hot when adam walked on them 🤣 nearly 2000f the firewalkers did it at 1000f
Fire walking is not faith but science it is nothing new this was proven how it exactly works almost 30 years ago nice repeat not new(s)
This is an old show and was entertaining. I did not know how fire walking worked until I watched this ep when it first came out. This show is not new(s)
