The two things that scare me the most in life is pressure and rotational energy. One second everything's fine and in the next, it's complete mayhem.

[@mortenhansen3455]

Like when your front bicycle wheels falls of downhill and the rear brake ..well.. breaks...

[@jeschinstad]

@@mortenhansen3455 That's not rotational energy though. It's more about things like the cutting whieel of a Dremel. The first time I ever used one, the wheel suddenly exploded and a shard hit my protective glasses right in front of my right retina, cutting a deep notch in the glasses. I would no doubt have been blind if I didn't wear them. When something is moving forward, like a bicycle, then you intuitively understand the danger, but when it's rotational, you just don't understand it until it's sudden mayhem. This is a great example of what I'm talking about: kzbin.info/www/bejne/d2XHlYykbtOdecU

I mean, i like Shopping. For Tools, for punky and gothy stuff in the secound Hand shop, for toys in the sexshop. But spending hours? Fuck no.

[@olenilsen4660]

About that water heater - I´ve talked to a few plumbers about this - and the safety valve is their main concern, actually. They do plug up, because nobody ever tests them. What saves the day mostly, is the thermostat. Because if it fails, it´s very likely that the entire power supply to the heater fails as well. After all, the heater draws more power, and it will corrode a bit faster, pretty regularly. Accounting for this in a Mythbusters test though, is a bit out of range, as it means a few decades of corrosion usually...

[@PaulOllech]

The safety valves for water heaters are normally pre-plugged.. they start out plugged with something like wax, and the plug melts when they get too hot. Makes it much safer and plug-proof to already have them stopped up.

Water heater rocket was peak Mythbusters!

....Air born taxi? Air born school bus?

[@LukeTheJoker]

@@mortenhansen3455 They were amazing of course, but the results were expected to some extent, I don't think anyone was quite expecting for the sheer explosive rocket that is the water heater.

[@alexhousakos]

Guess what happened to Chernobyl with the steam explosion from the vaporized reactor water. Imagine the boiler launch 100 times bigger.

[@MayaPosch]

Indeed, it flipped the biological shield on top of the RBMK reactor vessel like it was just a bit of cardboard. Steam explosions are terrifying.

[@TheScarab117]

What if someone had a pack of matches in their jeans while the horse is dragging them? I could see that happening and causing onlookers to think that the person's pants lit on fire due to friction alone.

[@PublicAtLarge]

It would probably take "strike-anywhere" matches for that to even be possible.

[@SigEpBlue]

Take a drink every time Adam says "hot water heater".

[@ludicrous7044]

When I worked for the Sheriffs department I saw the aftermath of 3 blowouts. ALL of them blew out walls and windows but did not move very much from their position. People in the house were scared but not injured. A natural gas explosion is WAY worse!! The worst one was when the gas company turned the gas off and later back on. The gas was not supposed to go back in the furnace. The gas built up and the pilot flame caused a BIG explosion!! An 80 year old man was watching TV in a recliner and him AND the recliner was launched across the street into a neighbors yard!🤧

[@JoseEncarnacao]

16:36 Hot water heater. Maybe this was the TV bit that got George Carlin so mad into making the "Play on words" segment in his 1977 HBO special!

[@idahagen9760]

The introduction to the waterheater rocket :D

[@ludicrous7044]

NASA would be proud!!

[@JonatasAdoM]

Quite poetic that they're using the pigeon truck as their base during the experiment.

[@LaraCroftCP]

The jeans shrinking myth is scary, good that i only wear leather pants or skater skirts. Oh my... Maybe Grant died because of this? Clots can stay for years and suddently can be flood to the brain.

[@Bram_Aarts]

Yep that was exectly what I was thinking

[@PublicAtLarge]

He had an intracranial aneurysm that had never been diagnosed and ruptured, leading to his death. While a blood clot *may* have caused it, there's no way to know now.

[@Wanton110]

What if the dude had strike anywhere matches in his back pocket?.. probably nothing, but still..

[@vonriel1822]

Episode title: "Blue Jean Mysteries" The thing everyone knows about the episode: Hot water heater rocket

[@Yvolve]

Grant's jeans aren't that tight to begin with so I wonder if the result would've been different if he was wearing the super skinny jeans available today. They are already skin tight and if you shrink those, it might do the trick. On the dummy of course.

[@matthiascerebri3315]

no, the speed is not doable

[@Yvolve]

@@matthiascerebri3315 Read my comment again.

[@olenilsen4660]

Nope. Denim is made of cotton. That´s what welders wear to ensure they won´t go up in flames... Also, the team will always have some safety measures in place for these tests. Poor safety measures (one tiny fire extinguisher on an ATV) means that the myth is busted beforehand. If this myth was at all plausible, Tory would at least have a fire suit on beneath that denim. More likely, they would let Buster test it first.

[@borntoclimb7116]

Good idea

[@NotMuchThanks]

35:07 was that a spark in those jeans?

[@soulofresolve9514]

No, that was probably an infrared temperature probe or something.

[@Godless_Guru]

In the uk we call fanny assessors gynecologists 😉😂😂

[@daniyalcolbert1671]

No, a fanny assessor would be a proctologist. A gynecologist does not work with butts

[@MrMarinus18]

American homes are so flimsy.

[@DragonbIaze052]

If you want to explode a hot water heater of that size in your house to prove how superior it is, go ahead.

[@Alexander-wx2ie]

It is because it is made out of wood. Other places use reinforce concrete and ceramic, therefore are sturdy. Also they last longer.

[@olenilsen4660]

@@Alexander-wx2ie Nope, we make most of our homes out of wood in Norway, but never as flimsy as the US way. Even better are the Icelandic housing where they have rules on how to bolt their walls, ceilings and floors together so their houses won´t disintegrate in a storm.

[@airi9673]

And yet it ripped 2 layers of 2x4 beans in half and those are used worldwide for roofs, in fact on EU, they're not placed as closely together as in US making a EU roof more flimsy, as for concrete and reinforced concrete, if it's able to contain the rocket it would instead make the entire room or house an actual bomb because of the rapid expansion of water, aside from it being a bomb, anyone within that house would die almost instantly from being steamed alive or from have a fool body 3rd degree burn

The water heater is pretty impressive. The jeans myth is not busted, its plausible, the Guy at 21:08 explain it.

How does a bath stay hot for six hours? That myth was broken from the start.

i like the episode but could you also use the metric system? That drives me crazy

At leat subtitles! I have a Basic understanding of imperial measurements but damn, i cant translate so fast.

Metric system? Isn't that the inaccurate system that is completely illogical and unusable. No we'll use real measurements, thanks anyway.

Lol blood doesn't freak Kari out, but chickn feet do. I guess I get it.

[@Games_and_Music]

I was kinda puzzled by that, because usually anything related to meat, skin or other animal stuff grosses her out. And i actually imagined that i wouldn't be too excited about filling blood baths and the smell of it, especially after several hours, but Kari apparently loves it.

Maybe this is the episode that gave Grant the aneurism in the brain…blood clot moved from his legs to his brain over time until it killed him years later ?

[@LaraCroftCP]

Very possible. My dad had something similar and had a heart attack. But he's fine.
