Adam: *Gets stranded on an island with a bunch of duct tape*
*Spends 3 hours making a hat out of it*
Well yes. But sun protection.
Typical libtardism lol
Legend
He did find the water source though. Plus the hat doubles as a cup/plate when needed
There's a reason hats were an essential piece of clothing right up until late 20th century. They keep you cooler in the sun, they trap heat at night, and a good hat can be used as a water vessel in a pinch.
"we're stranded on a deserted island with nothing but several miles of duct tape" that sounds like the plot of an awesome reality show

Thomas Devlin nah they’re close to a hotel if you watch part 2 you can see the hotel
I have not seen a fish in subnautica that looks like your logo
Reality Show
aren't real
The US Army taught us about solar stills, but warned us that making enough water to drink was not the point!
In order of importance:
1) They keep you anchored to one spot, basically immobile while waiting for the water to drip, drip, drip.
You chances of being found rise if you don't wander around. Your camp and stills are easy-peasy to spot from the air.
2) By staying still and in some shade, your need for water and food decreases. Less chance of falling/getting hurt. Less chance of encroaching on animal territories.
3) Staying focused on one task prevents 'option panic'; a state where desperate people will 'try anything' to save themselves. "Let's burn the tents and make lots of smoke!"
4) Hope. You see the water droplets form, you don't feel so helpless and alone. A sense of mastery is returned. Fear is displaced by curiosity. "Can we make the still work better?" instead of "Is the still gonna make enough water?"
5) You get enough water to wet your mouth and talk about your big plans for when you all go home.
Their usefulness goes way beyond the water they provide.
neat
Now that’s informative.
cool.
Thank You man. I had no clue about it
Everyone wants to have a good time....but you will not spend time!
Y'all just need two buckets of water and make an infinite water source
nrvinl 1 bucket of water and 1 bucket of lava for a cobblestone generator
Xd
You only need a single bucket in Terraria, though. :)
Minecraft
myo win what does that mean
This episode was my favorite when I was about 7 or so. I bought so much duct tape and made shoes and little boats and wallets. Thanks for the great memories
Christian Williams me too, I saw as a child too and I remember how great it was.
Duct tapes the best. You can make a boat with it.
Oh my god the duct tape wallets!! How could I forget?
I still do that every now and again after watching man vs wild.
“why does everything have to be so difficult?”
*mood*
Maddy Metzger *has mental breakdown*
Resident of Doggo world relatable hahah
Maddy Metzger did you know that behind the scenes these guys actually didn’t like each other? So what’s more difficult than what they were talking about is their relationship 😅😭 the more you know
King K’Lana oh wow haha i didn’t know that
K’Lana ooooooooooooooooooooooooooookayÿ
The water stil was a good idea, but I bet the duct tape seams prevented many of the drops from getting to the bucket.
Since it wasnt one big sheet of saran, there was no choice but to stitch them together like that. I think it did pretty well for 2 hours, maybe a shallower hole instead of a small pit mightve helped. Like build a wall on the inside of the hole to keep it from collapsing, so more wet sand was visible to the sun.
Would it be possible to make water stills out of giant leaves? Same idea as before, just instead of clear wrap, you use a huge tree leaf instead?
Cvo777 I mean not rlly since the sun can’t penetrate the leaves, but it might actually work if you left a crack for sunlight
Cvo777 wouldn’t be as promising and reliable though
The system really works, some people in the "brazilian desert" are using that process every day.
Here are a better structure,

With flex tape, Adam and Jamie has built a new nation with nuclear weapons on day 7
Your Neighbour Yes and flex seal
In a week
And inquinate more than Usa
Day 30, Adam and Jamie have engaged upon a world conquest with their rolls of ducktape.
Phil Swift here with an entire civilisation
If they had some Flex Tape on them, they could just repair the ship they came in using only Flex Tape and leave just fine, even through shark infested waters!

"I have to kill for a workbench right now"
-Adam Savage
bruh its just like, 4 wooden planks
how are they gonna get wooden planks
Adam has a Gamer skill, he can figure it out
@@raymondwu9506 punchj a few trees, each log is 4 planks and each tree has log 6 or so logs easily.
They used saran wrap from the pallet; pallet itself would make a good bench
Trees with square tree trunks?🙄
It’s ok, I’ll see myself out.😉
It's funny how I watched this on live TV years ago and it helped me once in a physics test in begging of middle school because one exercise was about this specific method and the cycle of water
3:49 Adam slurps the water...
Adam:"MMM! ITS FRESH!"
3 days later hes in the hospital
Nah the moving water is fine, it is still water you must be careful with.
@@Roof5tone i knoww hahaha it was a joke 😂
But ur right.... Moving water should be more safe than still water
Yeah you always run the risk of getting sick. But drinking from a moving water is a significant risk reducer.
You okay dude? I think you're reading a bit too much into what I said, it is not like I am sat here writing "Always drink moving water definitely and instantly even if you have the option to purify it".
Yeah I figured, just came across very hostile. Had to check up! ^^
In the Army, they taught us how to make a solar still using similar techniques. They had us use prickly-pear cactus as the moisture source.
When asked, the instructor admitted that the thing doesn't save your life by giving you enough clean water to drink every day, it saves your life because you stay in one place tending the thing!
Wandering while lost uses up more water than you are likely to find and it makes it harder for searchers to find you!
pretty sound reasoning lol
If I may ask a question. If it doesn't give you enough water to survive on, then how would it be of any use if a search party wasn't close by? Wouldn't it be wiser to instruct a person on what to do in such cases? Please know, I am in no way disrespecting what you were taught. I'm sure you know MUCH more about survival than myself. I only ask the question out of pure curiosity. Thank you🙂
There should be a general rule for everyone to follow while lost. Maybe stack rocks a certain way if you leave your original list point to guide search parties. Maybe break off 3 brackets and place em in a arrow the way you will head.
But isn't prickly-pear cactus edible anyway?
I have to say that while in a survival situation staying put could save your life. Depending on the situation.
Yes I always pack 300 rolls of flex tape in case of plane crashing
They were on a ship transporting containers of Chinese duct tape, when it sank in a storm off Gilligan's Island. All that floated up were our two hero's and a single pallet of duct tape. Tom Hanks should have been so lucky. Or something.
300 rolls of *duct* tape*
Having experienced brutal abdominal pain drinking straight from flowing mountain streams even when near their source I'd choose better made, multiple & well fed solar stills if there was no way to disinfect the water. You can adapt over time to the far less dangerous microorganisms drinking from fresh water sources but there's still always a chance you'll catch a real nasty one that can straight up kill you without medical assistance.
On an isolated tropical island, risk is reduced.
boil the water if u can?
I would definitely boil the water even from a stream like that. Nobody wants a brain eating amoeba.
@@DDeden Could easily have a bunch of birds up the hill poopin in the water.
@@PaperCut2UGaming Yup, or a dead one upstream. Always a risk, reduce where possible.
Now rehire the mythbusters and try with *Flextape*
THATS a lotta DAMAGE
Them
I sawed this island in HALF
Yes
I doubt this will ever happen
3:06 that *damn* sand
Kyle Haynes whooosh
Kyle Haynes clam down, it was a joke you aggressive, fortnite obsessed, Xbox playing nine year old.
Very Pickle no one thought that shit was funny g
@@sirpickle2347lol he deleted his comment

These guys literally have the best job ever.
Well, I’ll remember these survival lessons the next time I’m stranded on a desolate island with only a huge pile of duct tape...
I'll just bring my PLB along instead so rescuers will know exactly where I am when I beacon.
1:07 that's what she said
WTF comments 4:27 actually
He said
Alexi Sanchez no.. just no
My man!
( ͡° ͜ʖ ͡°)
at 0:53 i thought he had tiny feet XD
Twinkles
Lol
XD!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Fire Emblem Awakening anyone?
Twinkles lol
😂😂😂
Even though you wont get the recommended amount of water for survival it's still the easiest way to get it. Once set up it will continuously make fresh water for you as long as the sun is out. If I was there that's what I would do the less energy exerted to achieve a goal is the fundamental principle of survival.
0:18
These plants get there water somewhere I just got to find it
It’s called RAIN
and rain collects itself!
Pebbles ajpw yeah but i mean areas with water from the rain form on land, even underground
Warrior 34 there's also some underground
Exactly what I thought!!!
@Pebbles ajpw no the rain comes from evaporation
4:46 Me ay 3 am
Oh, you.
Sour Lemon that makes no sense
Sour Lemon omg
Izic Reyes ya it does
@Sour Lemon so u and his mom smack a plastic tube?
I really like that duct tape water bottle
But is it actually good? Cause that sticky part of the duct tape is on the inside where the water is stored.
@@jasonshox6861 I'm sure he lined it with more tape but hey, it's a survival situation.
Jason Shox looked doubled up to me
Mathew I will sell you one for $1000
Let’s make one with Flex tape
He didn't seal the edges of the still with dirt, allowing vapor to escape.
Also after only two hours I think it would make enough. Also the starting vapor took extra time to accumulate
That duct-tape waterskin is amazing, considering he didn't even have a good, flat area to work in. I wish the water still worked better, it's also an ingenious idea, I think Adam's point about seams is what kinda worked against the still. Amazing regardless.
Nah the results will be the same regardless and either way you'll be drinking the adhesive residue leeched in by the tape.
I wish the solar still were made better. He didn't try.
@@kishascapethe adhesive residue leeched in by the tape… was on the other side of the plastic. Jamie hung the tape then attached the plastic up. Additionally, they’re working with very minute incremental progress while collecting water. Every little bit of efficiency matters. With a streamlined system it would work.
4:46 minutes is my fav part lmao
Who gets stranded on an island with duct tape and plastic wrap?
Jesus that’s a lot of likes lol
a duct tape delivery boy
Christian Wetzel
Seems logical...
This was the duct tape special, where they show the many uses of the handyman's secret weapon.
You never watched Gilligans Island, I take it?
You can get stranded on an island with anything really - broken down boat with some random supplies, life raft, downed aircraft, etc. You never know what you'll have. Best bet is to learn to use anything that is remotely useful.
Adam even built the duct tape water bottle like an engineer
YOU just have to make multiple water catchers!!!
I don't think there was enough plastic wrap for more than one. Remember, their use of it was a grey area in the first place because it came on the pack of rolls. There still wasn't that much, though.
Imagine if someone ACTUALLY sees the S.O.S sign and try to "save" them?
they were only about a half hours walk from a hotal for safety the SOS was just to show it could be done
@@britishjack9931 everything was done to show it could be done, they even cought a chicken, but ate kfc
@@DanielSultana I know that I only mention the SOS because I was replying to Mena
0:10 that's a damn good lookin hat you got there.
🅱upreme
A boonie would probably be better than a fedora for hiking though.
Just loves how his beret fits his head perfectly
00:39 actually you can find water from that "balete tree" by cutting those roots/vines.
So the answer is yes- if you can find a freshwater stream 😂
Or you create like 50 of those solar thingys :D
Should have used clay or rocks to make the inside of the still wider, so more water evaporates. Should give him 100% of his RDA of water in a few hours.
he should have been able to get fresh water digging down 100 meters in from the surf line, to the water line , the soil should have filtered out most of the salt to a drinkable state , and he could have used his device to further purify the water if he felt the need.( and no i dont mean digging a hole 100 meters deep) , a plastic bag over a tree branch with leaves will also generate water . It dosnt even have to be transparent just as long as its waterproof like a tent fly or a a garbage bag
You can't filter the salt out of saltwater, that's why it takes a still, or in this case, a solar still.
Yes. At which point you move your camp to the water source; not the other way around. Carrying water would waste both time and calories, both of which are key in a survival situation.
I miss this show, I've heard the two never want to work together again but I would love to see even a couple special reunion episodes.
Discovery cancelled the show....they had a new project after mythbusters ended.
Just because you're not friends doesnt mean you can't be good colleges.
I love these guys. Always amaze me with their ingenuity
"Slaps water"
Survival Tip:
first find a duct tape and plastic wrap.
Need more mythbusting on survival myths!
If you put sea water instead of the boulder on top, you have a much faster condensation rate.
I love this channel! I actually could learn more things I didn’t know!
Love myth busters
Adam: Clearly these plants are all getting their water from somewhere!
Rain: Am I a joke to you?
No hate, just laughter
Myth busters was hands down one of the best shows out there, if they were my teachers at school I'd have learnt so much more
I remember this being my favorite episode when it originally aired.
moral of the story : the duct tape is a life saver.
The plastic idea is actually pretty good. If you set like 5 of those all day long collecting water. It's an infinite source.
@KawaZrana it would have been better if his salt water source at the bottom wasn't so small
good luck finding shit tonnes of duct tape and cling wrap
I don’t know why he didn’t bother to try to pour a lot of salt water in there too, have a lot more water to evaporate, although bear grills recommended peeing in it
It's not mine raft so there's no such idea as infinite water
@@sangun123 what if he had two "cups?" One full of salt water and the other empty? With all of that plastic, he could've had several of those up and running at once and in more visible light.
I remember this was my favorite episode when i was younger
0:36 Bear Grylls: "Better drink my own piss"
*IMPROVISE. ADAPT. OVERCOME.*
ur not funny dont like ur own commment
Well at least you're not the only one
I remember watching this show back in the early 2000's and now one of the team passed away 2 years ago and most of them stopped working doing this only adam is still doing videos
Jamie Hyneman is still alive as is Adam Savage. When do you think Jamie Hyneman died?
It was one of the others. The Japanese gentleman i believe
@@annethomson4920 Continuing the 'one response per year trend here, I think it was Grant that died.
Red Green would be proud.
If you don't find Adam handsome, you'd at least find him handy.
I have to watch this for school. I remember when this episode was new on TV
I remember watching them ever since I was 3, we were in my old house and me and my brother would just binge watch it, orange juices ready. It was the only time we could get along.
“It’s all ready getting moist!”
-Jamie
00:51 look at those tiny feet😂😂😂
That small waterfall and pond thing in the jungle looked so peaceful
Adam's in the shade, has all the time in the world to perfect his canteens b/c if he gets thirsty, the stream is right there, and beautiful scenery to boot.
Given that jamie got that much out of just a couple of hours it seems pretty viable to me. Leave it alone all day and maybe set up a couple more and you've got a water supply.
We need a Netflix for just science shows
I've seen so many iterations of this episode on so many different corporate channels. At least 5 different times has this been uploaded
Very interesting thank you for giving me a hint in my science project!
If you let it sit down before its necessary it may be a tiny bit more efficient.
3:36 I ask myself the same question every single day of my life 😂
I just started watching y’all and I love it already
incredible! I didn't know duct tape could be so useful. I gonna take a few to any trips I go!
Anyone else remember this from Voyage of the Mimi? That's how I first learned about solar stills when I was a kid. We watched all the shows in science class at school and then we did a project where we made miniature ones.
Omg. I loved Voyage of the Mimi
Who carries THAT much duct tape in ANY scenario? 🤨
I do
Everyone, you don't?
Who doesn’t
Real men. That's who. Bearded men. Obey the Beard
M. Happy I do
Red Green could have built an airplane in that amount of time and duct tape.
You could improve the efficiency by placing a bottle with a shoelace or something going into it from the middle of the still, that way water drips down into the bottle and can’t easily evaporate back out like it can with Adams design
This seems like it'd be really fun to try just as a challenge with a few friends, except for ya know, the dire catastrophic physical consequences if something were to go badly wrong.
4:34 he named the water bottle Phillip???
No he said hurry up baby fill up
Sick vid and I tried this in Maldives
Not many people know this but every deserted island has a pallet of duck tape on it
Quack.
The "Naked & Afraid" contestants should consider 1 roll of duct tape as the personal item to bring along. Perfect for sandals and water containers. Let the other person bring the fire starter or blade device. Most episodes prove that foot coverings are very important for transitioning to locations.
One contestant actually did! Unfortunately he was a smoker and caffeine consumer-he supposedly went cold turkey and tapped out...
It took me a second to make sense of the title.
To make it work much better use some green foliage underneath next time. Helps to build the moisture.
Lol. That’s in North Shore Hawai’i Oahu😂😂
They left out the part where they catch the wild chicken...from KFC.
Why doesnt he try to tap a vine or a tree. They give off quite a bit of water
Never gettin bored with mythbuster 😁😁😁👍🏻👍🏻👍🏻👍🏻
As a chef I have always thought of shrink wrap as the sibling to duck tape
How to survive in the wild Guidebook:
Step 1. *_Have a massive load of Duct Tape and Plastic Wraps._*
You’d need something to have the water to droop down into the cup, like a small rock or stick.
Also maybe this works better with something black.
And yeah, trying to find big ass trees so that a waterfall or pond could be collected from.
One problem though, you gotta worry about parasites!
if the cup is clean of sand there is no worry, parasites don't evaporate
The shape of the canopy does it mostly for you. Cohesion keeps the droplets on the cling film until they reach the epicenter (lowest point), and gravity eventually becomes the stronger force as moisture collects on itself.
this was my all time favorite episode they did
You can always duct tape large leaves into collection bottles. Or use the round shape of the duct tapes to make water bowls with a lid on top.
Man I miss Mythbusters!
Missbusters
3:39 why does everything have to be so *cOMPLICATED*
Damn, i miss these two. Favourite show ever
I’ve basically done a solar still when I was a kid to wash my hands without going to the ocean. Yes I was weird
They are living legends !
“When in doubt, Duck It!”
-Some Jersey Guy
Gotta love mythbusters great work guys
I would first make a duct tape fanny pack to carry everything that could be useful
You just make more of them.....its a beach ffs. Large leaves tied over the hole should have a similar effect - creating humidity instead of needing clear plastic.
actually it's very important for the plastic to be clear so that it creates a greenhouse simply using leaves wouldn't produce enough condensation and thus wouldn't work personally I think his issue was that his solar still was poorly made rather than it simply not being a reliable source of water
I've seen it done before, with the sun beating down on the spot its possible to get some humidity going.
Johnston Steiner They've done that zombie experiment with multiple weapons...
Wrong, they never produce enough water to be sueful @@degiguess
In Australia which I read in Australian Geographic Magazine (unverified), we tie transparent durable plastic bags around plants leaves/branch to utilise condensation to collect water. I haven't seen that shared in TH-cam survival videos. Please investigate the aforementioned and maybe do a video to share with people to help save lives. Thanks. : )
This was the weirdest and coolest videos I've ever seen, but I love it
I’m sure we can give a pass to Jamie for using the wrapping. He did use the duct tape with it. Plus making a solar still purely out of duct tape wouldn’t work too well.
Like any survival guide/course will teach you.. No, they cant.
At best they will supplement any other water source you can come by in a survival situation.
Yep...And collection time? About eight hours...nothing quick about it.
