Mythbusters season 01: We're going to use the scientific method to debunk popular urban myths and help people find a scientific and critical way of thinking before believing or dismissing new information.
Season 07: We make stuff blow up... for science.
Absolutely loved this show when I was younger. Im thrilled to found it again being uploaded to RUclips. Original language, no TV breaks. Amazing! Keep it comin'!
Oh well, we were all younger back then. Good times. ;-)
The last good TV show, imho.

These guys had the right idea to quit when they were ahead. So many previously good shows turn stale and dull when they should have called it a day long ago. That way Mythbusters will always be watcheable. 👍
I totally agree with you, I just wish it didn't have to end, one of my all time favourite TV shows ever.
@fishingfan1500 that's what they say in "showbiz" isn't it - always leave the punter wanting more
They did 347 episodes ... 💸🐄😄
You forget all the new 'mythbuster' spinn offs discovery is doing
i think they would have had a couple of seasons in them at least but discovery just didnt want to pay them anymore.
i guess you need quite a lot of money to play friends for that long. always disturbed me that adam and jamie hated eachother
I think the myth with the bubbly water came from people who have tried to swim and drowned near hydroelectric dams or weirs. Contrary to popular belief it's not the water density that kills you, it's the downward current nearby. The bubbles are just an indication of where the currents are. If the bubbles appear several feet from the dam, it means the water between the bubbles and the dam is moving like a large rotating drum that's pushing you towards the dam, so you can't swim out of it. Many experienced swimmers have died in such waters while trying to save someone else who was already in there.
aerated water can kill you though, here is a small scare demonstration done right rather than the example mythbusters did in the video: ruclips.net/video/VPmTgsWFtSA/видео.html
one example i can think it couldve come from are aeration tanks like the ones used in wastewater treatment plants. They aerate the water so the bacteria breaking down the poo have plenty of oxygen. Due to the introduced air, it has no buoyancy, the water density is low enough that someone who falls in will go straight to the bottom and essentially drown in inescapable poopy water 😅
50-51 degree sounds like a nice hot bath to my celcius brain
Rest of the world brain....
I hope that those sheep grazing just outside the bomb range fence understood what "fire in the hole" means.
They've probably had worse things in their hole.
I look forward to watching these every day
2:50 I could watch that part over and over again XD
Me too xd
its a SNake
what about his one 39:22
@@artemisknightprotectorofth8956
That one was good too, but not _that_ funny. The hose freaking out alone wasn't that good either, the cap flying off afterwards, just like an exclamation point, that's what made the whole thing so funny, even on repeat.
44:10: 'The decrease in density RELATIVE TO ITS SURROUNDINGS causes a current'. Exactly! The reason for the current that threw off the whole test was that there were always parts of the pool without bubbles, where the water could flow downward. If they had covered the entire pool floor with bubbles, or just done it in a rectangular tank with the same shape and size as the bubbler, there would not have been this current.
It is beyond me why the voice-over is at such a low volume level with these uploads. It is as if it was only on one of the two original stereo channels and the uploader had only the other channel fully 'open'. When playing this video from YT, it does not make any difference whether that would be in stereo or mono mode though.
i think its accidentally gone through a mid-side conversion but not fully done. what should be in the middle is now on the left and what should have been the 'sides' is now on the right.
or some kinda 5.1 channel mapping mistake or something?
2:50 That was hilarious 🤣
Rest in Peace Grant Imahara
Forever missed
Always remembered
what about jessi
the bubbles were too fine
The cut with the double explosive arrow. XD You know damn well they couldn't shoot that safely and just stuck the arrow in the tree and set the fuse. The arrow sound effect XD Love this show still.
The only way the dynamite on a tree would really work is if there was a big enough crack on the tree to bury it into. The blast on the tree's surface is just going to for the much less resistant air around the tree rather than trying to go through the tree.
Every time you jump into the water you're swimming in bubbles
classic mythbusters. we tried one type of wood, and none of it works
21:23 makes Star Trek reference while looking like a Jawa :V
As an explosives expert… !
To split wood you need 25mm holes 2/3 into the trunk- and Max 30cm between Them… Dynamite would be okay! But just Max 30gram/Hole !
That would do the trick💯
the good workis👍🤜🤛
ain't what Jamie and Adam made just a grand scale jacuzzi?
All I wanna Know is Did Adam use the age old method of keeping warm in his wetsuit? Taking a leak inside it😂
The explosive on the arrow couldn't even damage the arrow in the first test.
Fireworks have a stronger punch...
Ok you audio complainers, after 10 or 15 minutes on the web I've found the fol: Season 7 aired in 2009 (15 years ago). Largely to an audience of TV watchers with either mono or stereo front facing speakers. The gen 1 iPad came out in 2010 with a mono speaker and remained so through gen 4 in 2012. The iPad Mini was the first Apple device to have stereo speakers in 2012. Similarly, the first "real" Android tablet was released in 2010, the Galaxy Tab, basically an embiggened phone. There were a bunch of cheap ones too. I couldn't pinpoint the speaker config but it was likely mono as well. I'm disregarding phones since even my s10+ has a mono.
Your external speakers or from a TV will sound fine, aside from some audio balance issues by Banijay, or even just walk away from your device and it'll sound fine. Your TV is 6, maybe 10 or 12 feet away so it blends fine, not a foot or two from your face place. Headphones or built in stereo speakers on a current tablet will obviously sound like Robert is on the left while the crew is on the right. My tablet has a 4 speaker stereo setup clearly having this issue.
So... If this was the way the audio was originally designed, and as of when this was aired, it'd have sounded fine as well unless you were ear humping each speaker on its own.
Oh, as an aside, Banijay does have the rights to upload so it's not a scammy rip and post trying to avoid copyright. It's on their site along with a bunch of other content.
I do wonder what would happen if linear shaped charges were used instead.
Wonder if a single vertical slice with a chainsaw then one strand of detcord might do it.
You guys should have just asked a surfer. Every surfer worth his or her salt knows that you can't stay afloat in foam. It is every surfer's nightmare, drowning in foam! But I love the makeshift engineering!
I would have tried blasting cord
if ppl look at swimming and when they jump from high up there is bobbles in the water to, to break the surfers so they don't hurt them self that much landing. and in one of the first mythbusters the did the myth to.
The aeration thing is absolutely real as its caused deaths in the past especially in "modern" waste water treatment facilities when people have accidentally fallen into actively/highly aerated "water"
I think there are a few verifiable cases documented. The aeration systems in modern plants are much more comprehensive, complete & intense than what is used in this pool.
Edit: this test is severely hampered by the single bubble source
IMO ALLEGEDLY
I sometime do welding jobs in water plants.
I am on your side. The aeration is much more complex, covering every single square inch of the container sometimes even layered at the bottom AND side walls covered in jets.
I hope my english is good enough...
There are several recorded deaths in such aeration tank and there are specific warning labels. Hard to believe international and german safety organisation base their knowledge on "Myths"
Two thoughts:
1) as mentioned above every square inch and even the walls are aerated. So there is no space for one large "convection like current" (middle up/Sides down) but possibly a whole lot of those with currents strong enough to pull you under in the middle of the Tank...
2) all that bubbly water splashing means it is very hard to keep your head up and water out of your face/ mouth...
I would not hesitate to swim in natural bubbly water.
BUT
Aeration Tanks are a whole other story....
Kyle hill has covered this on his channel.
@@mats6565 Can't watch that guy.
It is 100% true. I worked as an Electrician in a waste water treatment plant during my apprenticeship. And if a Bird tried to land on the aerated water, they do not flow a tiny bit. They simply sink like a stone. But the amount of air that is pumped into these tanks is crazy. We had to service one of these turbofans. The steel blades got sharpend by the air to a razer sharp edge. You heard correct Air is grinding off steel from the blades (@ 60000-90000 RPM).
@stevenhoff that's caused by cavitation. The tiny bubbles explode at the edge of the blade causing massive damage over time
36:42 Why not use target explosion or how its called,same way you can easy cut very thick metal plates in one second.
You mean a shape-charge. Was thinking the same.
@@weilwegenissoundso Yes i forgott how its called.
So he does not know how to use his legs while swimming! :D looks like is just randomly shaking them
Bubble Trouble - MythBusters (Season 9, Episode 4) not S07 EP02
They mixed up the episodes numbering completely. Same with season 5 that actually is a season 7.
I sincerely hope they cleaned out Adams sick from the last time, I shudder to think what would happen if a saw 2 year old sick float past me
Why didn't they go to a swimming pool with a diving team? They have air systems pre-installed in the floor.
😊😊😊😊 cool 😎🎉yyyy yes ❤
all you had to do for the swimingin bubbles myth is ask a kayaker
Once they brought in all the side kicks these episodes went from great to bad
❤yes😺😸😸🤜🤛🐩
Would have a better chance using different trees, softwood branches grow right to the heart of the tree making hard to split. Should of tried hard wood.
I've only watched the first few minutes but for the swimming in bubbles question, flotation will not be impacted as long as you stay where there isn't a lot of vertical water current (created by the bubbles). Your ability to push against the water and move yourself (swim) will be reduced though. Why?...
Floatation is actually caused by an increase in pressure the deeper you are in a liquid and a reduction in pressure the higher. The fact that some of your body is deeper means it gets more pressure on it, pushing it upwards more that parts of you that are higher up.
In order for the air bubbles to exist and not collapse means they are at the same pressure as the water the bubble contacts. In other words it doesn't matter if water or air bubbles are pushing on you, the pressure is still the same and the deeper, the higher the pressure is.
Actually swimming though, where you move your arms and legs to push against the water, will be less effective because the air will move more easily than water.
Edit (added after watching...): the reason the bubbles move upwards so vigorously is, even though they are at the same pressure as the water, they are much less dense (weight per volume), so they don't have enough weight to compensate for the flotation forces (ultimately generated by the variation in pressure (deeper = more pressure) surrounding the bubbles.
The vigorous flotation of the bubbles generates lots of water current, which in turn makes it difficult to swim in certain regions of the pool (or wherever the water filled with air bubbles is).
Agreed .
I repost my answer to another Poster here. Perhaps you have some ideas to my thoughts and description of aeration tanks...
I sometimes do welding jobs in water treatment plants.
The aeration is much more complex, covering every single square foot of the container sometimes even with layered jets at the bottom AND the side walls covered in jets.

Two thoughts:
1) as mentioned above every square foot and even the walls are aerated. So there is no space for one large "convection like current" (middle up/Sides down) but possibly a whole lot of those with currents interacting and strong enough to pull you under in the middle of the tank...
2) all that bubbly water splashing means it is very hard to keep your head up and water out of your face/ mouth...
I would not hesitate to swim in natural bubbly water.

the arrow has to be sharper and more powerful, then shoot at the top of the log.
In the season 1 episode about sinking ships, didn't they sink a hydrometer with bubbles?
ruclips.net/video/AL2TCqdCqOU/видео.htmlsi=P0Ok0WOPqJK_Su2u
Assuming that the seedlings are not eaten by wild animals, two of them will die anyway, as you cannot plant trees that close to each other. They will fight over resources like water and light and in the end, one of the three will win and that's bad news for the other two.
Yeah but they get to feel good about planting three trees. Just like TeamTrees got to feel good even though the money they raised made almost zero difference.
The problem with the bubbles is probably that they create a current. If you space out the bubbles across the whole pool, you'll possibly get a different result.
what about methane that whould able to sink a boat in the ocean or river
2:48 Adam loosing control of his hose....
Is there a chance to not having the narrator on the left channel only? It's really annoying when one is watching while using headphones.
Do you normally swim in a wet suit
so it turns out that wood is actually many many many times stronger than stone!! take that minecraft
I swim in bubbly water all the time especially when i fart! was the myth swimming in bubbles or floating in bubbles
Thumbs down for them hurting trees in this one. :C
Would have liked to see Adam take off the wetsuit to see what happens .
There are giant locks between ocean and sweet water. Guess how they keep salt water from flowing into the sweet water? Right, a large air bubble curtain. Ocean ships simply pass it, but yachts really need to use another lock, labeled Recreational Lock. Why? That air bubble system sends "small" boats to the bottom of the lock. No idea why James and Adam did not visit such an air bubble lock.
Don't you have a jakuzzi?
Smells like pizza
17:01 FIRE IN THE HOLE!
The dynamite in the tree myth: we’re not gonna use trees, we’re not gonna shoot arrows ourselves, we’re not gonna use real dynamite… We are gonna test the myth for ya!
You know how they always stand in three and watch behind that screen 27:53, it would have been nicer if they had the explosives guy standing with them, not way off in the background, I think he earned it considering.
Also, I like Adam but I wish they had Jamie doing more, instead of always getting Adam to do all the fun bits. Jamie's seriousness is precisely what would have made it more funny, when putting him in silly situations. I think it would have helped them get along better if it was more equal.
I would have liked to see them use dry ice as a source of bubbles, I think the overall spread and amount would be superior to the "mechanical" bubbelmakers they used. Naturally they couldn'tswim in that water.
Why is he wearing a wetsuit while swimming
Probably cold, San Francisco doesn't typically get very hot anyway
Okay I can barely hear the narrator in this one. What the fuck is wrong with it??
I can hear it well I think is a your problem
The narrator is only on the left side for earbuds, which is a recurring thing on this channel, probably to do with how it was imported to youtube from tv.
I think you meant to say "thank you for uploading yet another episode of the Mythbusters I can watch for free"
@@sylvaingilbert6296some people are so ungrateful
@@christianmirto1597 Yeah well, he is veery quiet compared to the boys and Kari, although I can hear him only on my left speaker. I guess I'll watch on PS5 from now on as before...
