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.

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.

[@nicks4802]

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 🌠

[@jinstinky501]

You missed a big one. Use salt water.

[@BathtubBass]

It put out the fire! LITERALLY FLAMING

[@josefolsson5343]

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.

[@gabriel72737]

Why the hell there is a "firewalking institute of research "???

[@Games_and_Music]

Because charlatans need to finance their grifts.

[@simonvanootegem6643]

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....

[@scrivener68]

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.

[@Shakes-Off-Fear]

When the coals are that hot, any amount of dew would have made little to no difference.

[@scrivener68]

@@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.

[@julmdamaslefttoe3559]

100% didnt help. but also grabbing coals with your toes isnt a great idea lol.

[@MrMarinus18]

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.

[@DavidRichardson153]

​​@@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).

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.

[@Johny40Se7en]

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 😅

[@Games_and_Music]

Yeah exactly, i was wondering the same about a water/stun cannon truck.

[@patrikhjorth3291]

I'd like to see a dry chemical extinguisher tested in an indoor fire. At least where I live, those are the most common extinguishers found in private homes, and the chemical agent is released by the fire. It is most effective in an enclosed space.

[@333maddoxtj333]

22:27 - " oh okay" 46:52 - and that's literally a proton pack ray

[@malusignatius]

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.

[@benoit7430]

Adam said "salt water" during the demo.

[@malusignatius]

@@benoit7430 Cheers. I wasn't sure if it was mentioned or not.

[@Netbug]

[@alexanderkrauss6266]

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?

[@zeizei6th]

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.

[@borntoclimb7116]

I love the tesla coil experiment. In Germany near München we have similar stuff. The stungun with water is pretty impressive.

[@user-ve5ei2xe8h]

15:01 - best moment.

[@kineticsyntax]

Mythbusters: "water stun gun is busted" Allen pan: "Let me show you how its done"

[@igttgit]

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"

[@kineticsyntax]

@@igttgit I agree people increaseing the pressure in their water heaters is a great idea.

[@lloydsumpter7735]

I would think all that water would short out the zap - less resistance than a human body.

[@barbugia123]

That reference at 2:40

[@Games_and_Music]

The water stun gun can still totally work, if it's on top of a vehicle, that generates the electricity by driving, or actually just has a Tesla coil up there. I wonder how well it works with oils, as it will keep a tidier stream, aside from the reduced usability (oil is messy on the streets etc.) But it could be a watercannon with a bite. I do wonder if a mist will also increase the chance of nearby targets getting zapped.

[@cejannuzi]

Poor Adam...and his feet.

[@Theviewer100]

46:43 that looks unreal 😮

[@Myrddraalfade]

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.

[@zsoltbartus169]

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.

[@bueb8674]

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.

[@Tjescoo]

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.
