This clip was only the first half of this particular myth. In the second half they put a to-code mini house in front of a large wind machine, and they discovered that the effects of wind in open vs. closed windows was negligible. They also added in water and flying debris and came to the conclusion that it's better to close and shutter your window due to the water damage you would suffer during a hurricane. Also, it was said later in the episode that the size of the windows in the scale model were that large to exaggerate any effect that might happen.
It's extremely misleading to show only the results of the small scale without the final conclusions of the myth. Especially with the note this video ends on of a "myth confirmed" vibe instead of the busted conclusion they ultimately reached.
Tecorsuh this should be the top comment; the first dozen point out the limitations of just this particular experiment.
"Science Channel"
I get that the point of this clip is to advertise the show and get you to go watch the show to see the entire myth, but it's misleading time to stop watching the myth. It's deception.
Thanks for pointing out about the water and debris. Hopefully those who would actually consider exposing themselves to the elements during a hurricane after seeing this partial video will reconsider after reading your post. This video is dangerously misleading for anyone inexperienced in dealing with hurricanes. They could be in real trouble if this video was the only data that they had to work with..

Totally agree... It's completely backwards to the point of the show to include out of context clips that are completely misleading
Yeah if your house is a perfect square with a 1 equal size window on each side
ebcrew with no walls inside as well. This test is not realistic😂
Haha not their best.
Like others have pointed out, this is an out of context from the beginning of the episode, they went on to decide on it being busted...
And without anyhting inside
@Obsidian Rose only idiots would trust somthing on youtube
and no 1 cares about idiots lol so they can die
Well there’s rain and, Also those windows are not proportional to the house who has windows that take up 65% of the S.A of the house
erik olsen ..hi Eric! What do you mean? Lil confused about your message & abbreviation s? 😎🦅🐺🐾🐾💙✔️✔️✔️
TangoCrunch if that was the case it would be obvious of course something with holes in it has less air pressure against it in a wind storm the title of the video is something like does your house take less damage with the windows open in a hurricane and that would mean this had to do with a house in a hurricane and with that being said during a hurricane there is copious amounts of rain the wind changes directions all the time and there is flying debris if you leave your windows open you will ruin all of the contents of your home due to the fact there will be a minimum of 4 inch of water on the entire first floor of your house another thing about this that is ridiculous is that hurricanes don't have that much wind Force 160 miles per hour 180 at the most compared to a tornado and the 250 to 300 tornadoes do structural damage to any home hurricanes only damage homes that are not built to 1980 standards and it home built after the 2000s along the coast of America all are going to have extremely high hurricane tolerances last year my house built in 2005 went through Irma Category 3 to hit directly on Fort Myers where I live I only lost one piece of lattice not a single shingle came off my roof gust of 145 miles per hour this is ridiculous this proves nothing
erik olsen ...what's SA of house n windows open..don't worry about material things! Just save yourself & fam., Pets, however keep safe.. wear lifevests and shield your self somewhere safe. Period! Hurricanes depending your location are pretty darn destructive sometimes! Any suggestions about tornados? Just curious! X..🐺🐾🐾🦅💜💛💚🙏✔️
I feel it's genuine!
ssjpacman ....lol 💚🐺🐾🐾
Note in Jamie and Adam's test house, the wind can flow through the house unobstructed. But houses will always have interior partitions which will interrupt the flow of the wind. In fairness, I don't think their test house models reality all that well.
There is still a lot of stuff inside the test house, as those cylinders are really fat, but they definitely should have added at least one wall across the whole thing, with openable door. This model simulates a house with all of the internal doors open, so probably the worst thing to do would be opening the windows and closing all the room doors, as that would give the baloon effect as well as let in the rain and more debris from the hurricane destroying things outside.
The biggest problem with the test is the roof most roofs aren’t like that and are pointed. This caused a difference in pressure and will literally rip the roof off the house
This is only half of the test. In the next half they busted the myth.
The second half of the test used a to-code House,this is only the first half
There's a reason we have hurricane shutters on houses at the OBX. The houses that left windows open or had their windows broken were basically destroyed because the winds traveled through the house and created furniture projectiles or pushed the roof up/walls out (not to mention all the ocean spray and sand that made their way in). I dunno anything about tornadoes in this scenario, but it's much better to keep them closed during hurricanes.
No, open Linux during a hurricane instead.
Was looking for this. Thank you.
Will DOS work?
What distro?
Ha!
Pfff, Linux is already open.
Except that houses aren't one-room structures with no interior walls.
Yeah which they cover in the actual episode ya dingus
Some houses are if your really poor
one word,
_AFRICA
@@eethanni More like China
@@youcansave15ormoreoncarins75 the houses are usually connected in china so the windows dont go through
In hurricanes, the rain travels horizontally. So, here's the tradeoff. A house built to a modern code in South Louisiana can probably withstand 100 mph winds with minor amounts of damage. (My house, built in the mid-70's, required roof replacement after hurricane Katrina.) If you leave all your windows open, you will likely have to replace 100% of your carpet, and 80% of your furniture. My plan going forward is the same as my plan to date: keep my windows shut.
You're right. Having everything inside destroyed is just as bad as having part of your house destroyed. Might as well keep everything shut and the inside protected.
Here's a tip avoid the coast.
imagine having full room carpet ☠
Yea but nothing inside will stay intact
Bubble Baath yep
Apparently opening the windows helps balance out the air pressure too. 'Windows open' works in 'Straya by the way, especially when having cyclone parties ;)
The narrator brings back so many memories :( rip Mythbusters
All I know is what I actually did through 2 hurricanes, Charlie and Irma. I boarded up the windward side of the house and open the opposite side of the house. Both times we made it through without a single scratch on the house, no damage at all. The eye of Irma passed right over my house. I went outside to stand in the eye. It was really strange. These were 2 different homes in 2 different locations.
"opening the windows results in less property damage"
anything inside the house: adios
but the one inaccurate thing, there stuff in the house the can cause more damage and possibly hurt people, your demonstation only shows the structure of the house, which is obviously end up getting good results.
Opening your windows is standard operating procedure during a hurricane in the tropical north of Australia.
I love the voice-over. So relaxing and nostalgic!
As a hurricane maria survivor i can say, this would be horrible to do in a real hurricane 😂
The rain? Dirt? Palm trees?! Where are all the real hurricane conditions. It’s not a hurricane unless you have at least 6 palm trees flying around.
Love your comment Dr Rice! Will never forget to count the flying palm trees from now on.
I live in a place where we battle an average of 20 hurricanes a year. For thousands of years, our traditional architectures developed 2 ways to adapt.
One uses light materials with windows that allow wind to pass through. Our windows are so big, perhaps bigger in surface area ratio. Its so true.
The other uses heavy materials that looks more like a hole dug on the ground. I mean we have earth for roofs that merge with the landscape.
The basis of the test is not about your possessions, or the carpet, wallpaper, paint, any of it. The test is strictly about structural damage, and in theory having all windows open would definitely lead to less structural damage. The thing about high wind, is that the damage is due to high force over a relatively small surface area. A flat wall will experience far more force than one with an opening. Any drop in surface are means a drop in force applied to that wall. So by opening all the windows, theoretically your house could be the only one left standing in a sea of rubble. Your possessions may take damage, and the repair costs will be incredible, but you don’t have to buy an entirely new home, as well as all new possessions.
You forget about the roof. It will create an airfoil (like a plane wing) and the roof will be torn off the house.
Daniel Gonzalez i don’t think you entirely know what you are talking about. “Airfoil effect” is not “like an airplane wing” that is exactly what the airfoil effect is, and only applies to plane wings, unless you think the average house is perfectly shaped and designed to affect wind in such a way as to create lift. Which they are not, in case you don’t realize.
pyromaniac000000 the way a airfoil works is through the Bernoulli principle we’re if you have air faster it creates low pressure. Hence the shape of a airplane wing is curved to speed up air on the top of the wing (think about a hose if you squeeze the top the water comes out faster) . Similarly on a house the roof will cause the air outside to move faster vs inside creating pressure difference and essentially creating lift.
Daniel Gonzalez first of all *an airfoil, secondly thank you for better explaining yourself. But it still isnt entirely correct, pressure difference would not magically equal lift, for lift to occur it also has to be shaped in a way as to create that lift, which a house is not. If everything was as you say, a vacuum chamber would magically levitate into the sky. And besides, in a storm like that, your house will probably be in the sky anyway. In the sky in a million tiny pieces.
a box wouldn't magically fly into the sky because the lower pressure is on the inside which means the pressure would be placed on the outside in so it would be crushed unless you have a strong enough box to hold the vacuum and if you had it vise versa the pressure would be put on the inside going out and it would explode like the pressurized tank of air in Jaws. The thing here is a box is not equivalent to an airfoil. Second you miss my point that the shape of a roof on a house is like a airfoil. Flat on the bottom rounded on the top. It doesn't have to be perfectly like a real life airfoil to create lift. Airplane airfoils are the most efficient design for lift, that doesn't mean a house roof wont generate lift.
I feel like the windows are not scaled properly to the size of the house. Also houses have an attic that have their own openings and interior rooms and walls that obstruct the free flow of the wind.
It would also depend on the cross-sectional opening for the window provided + the orientation "you might not have a smooth ventilated house,there are always partition walls blocking the winds"
I read the title asking myself why you wouldn’t be able to open Windows on your computer during a hurricane
Totally backwards from a tornado where opening windows gives the tornado a better grasp to rip your house off the ground
Can't wait to test this on the next rain-less hurricane.
Only if you live inside a perfect squared capsule without any furniture like that
Wind tunnel does not replicate the reason behind people recommending opening windows...
The purpose is to allow air pressure in the house to equalize with pressure outside more rapidly, since you get rapid air pressure change as the hurricane passes.
As the low pressure system passes, the fear is that the house will pop like a balloon that has been overinflated.
But that pressure change is still slow enough that even the best sealed houses would be unlikely to have measurable difference in pressure from inside to outside and the house can withstand a few pounds of difference.
They forget that houses have alot home products that aren't screwed to the walls or floors that the wind can carry and destroy and possibly kill someone
That's amazing! But all homes are different such as the layout, structure, etc. Especially the position on where your home could facing with the wind, it could blow anywhere, the wind could blow on the front of your home, the back, the sides, or maybe the corner of your home? Plus any furniture would start flying and be soaking wet.
I believe it hat if you are in the house and the pressure of the hurricane goes through the house, and you are in it, I could assume that one would be hurt in this scenario. Though it may preserve structural integrity, anyone inside could potentially be hurt.
I advised this in 2012 and I only lost my siding during 85mph wind. Other homes were mildly damaged
Less stress in the house structure, more stress into the objects INSIDE the house lol
this wouldnt work in a life size house because the ratio that a window would cover is a lot less, so the wind would grip to the house walls instead of finding the path to the window
Witch Hunter this wouldn’t work because the roof would create a airfoil and rip off the roof
I always thought it went that you should leave the windward side windows open an inch or so, while trailing windows were fully open. This minimized internal air pressure, decreasing the chance of the roof being lifted.
Less structural damage, but more internal damage due to wind throwing stuff off shelves and all other things you can imagine.
Lesson learned: Just remove all walls, to remove pressure on the walls :-D
No house, no pressure😅
Good way to turn your house into a swimming pool. At least here in Florida, Hurricanes bring massive massive amounts of torrential rains.
Why don't their just build the homes out of concrete and/or steel to survive the twisters?
or do like the Native Americans did in those areas and build them in underground mounds. Native Americans always built houses according to the elements. Places with flooding had stilts like in the Mississippi delta. Places known for high amount of tornado's were built in underground mounds. Adobe was for the southwest deserts, and in Florida the Native Americans never built houses near the coast/beach areas. The European settlers come in and do what they want and they suffer their fate for not thinking of mother natures wrath first.
COSTS $$$$
High cost
Leandro de Oliveira if it's costly to build why all European countries even the poorest ones build them?
Meg.A. Byte Here in England in Europe all houses are brick.
The Insurance Institute for Business & Home Safety recommends that you close all interior doors and all windows for major wind storms including hurricanes. That's because wind that enters a home through open windows creates strong upward pressure on the home's roof.
Not a test that can accurately replicate the hurricane conditions, for a number of reasons:
- Windows are way oversized relative to the sides of the house
- typical houses aren't a square or rectangle, they have a lot of protrusions , and irregular in shape. Wind would meet resistance and when trying to blow past the house.
- The wind in the test appears to be hitting the sides head-on, which is usually not the case in life. Wind would hit a house from an angle.
- All the interior walls and furniture inside a home would offer a lot of resistance to wind trying to pass through an open window
I guess they need something to do but its really quite simple. The more surface area the wind hits then the more total force there will be. You could tell how much difference in force there would be by simply subtracting the surface area of the windows from the surface area of the wall surface. But this is only if the walls are perpendicular to the prevailing winds.
If the wind is hitting the house at an angle to the walls, depending on the angle and width of the windows, there may be very little difference at all in force on the wall when the widows are open or shut.
Observer ..ty so much! Wasn't getting any answers from Erik .....😉🐺🐾🐾💙
You are most welcome Holli
It's not the stress on my walls that bothers me. It's what a 100 mph wind blowing through my house will do to my interior. I'll take my chances with the walls to avoid that.
So you're telling me to buy 60 ft of aluminum stovepipe, run it through my living room, and build a big vortex funnel on the windward side? :thinking:
That's when you're supposed to move to a actual hurricane test on a scale model of a house built to code
It would make sense for the air to flow freely throughout the house and not cause the house to balloon up. On the flip side, all that wind and rain water is now saturating the whole house, which will destroy pretty much everything, then the black mold starts to form.
Well, that house DOESN'T HAVE FOOD AT THE KITCHEN TABLE IN THE MEDDLE OF HURRICANE!
...they should also take notes that every house has walls internally as well.
But the problem is THAT'S NOT A HOUSE. That's a shed you build in your back garden .
Interior walls and rooms though, it will block the wind from going out the other windows.
science! but also the purpose of closing everything is to protect everything inside the house so more or less you'd probably prioritize keeping yourself and everything inside safe vs keeping the structure safe (which is important too so you need to check the structural integrity regularly).
since were measuring wind resistance, the shape of the house is also a factor to consider
That rig is so damned elegant!
In my head it sounds like I should, but i'll get a whole lot of cleaning afterwards
This fits perfectly with my house.
this gives me an idea why not have attic space or Walls to be built wider to have Tubes that runs through the house and have an add on to the outside of the house that act like a funnel to move the wind into the tube and let it flow freely out so that as the wind hit the funnel it get move toward rather then pushing. and as a bonus you could install Fan blade in these tubes to generate power for you house during a hurricane storm so that you could have some power powering key things like an outlet for charging a phone or having lights to be one or a way or just plan ass storing massive ammount of power in batteries.
The house I live in isn't shaped like a box with a window on each wall
I live in Florida, had my front door open for Irma and was outside the entire time.
So you have to decide either let your walls break or let everything in your house break.
The cameraman has his arm broken...but keeps on working.
As a Texan who has lived through multiple hurricanes, the wind isn’t my biggest concern anymore, it’s the damn storm surge.
the problem with this is test that theres a friggin window right behind the windward window.
Thats not how most houses are designed. There usually isn't a window behind the windward house that the wind can just go through
Closed for hurricane, open for tornado
"Should result in less damage"
Yeah except for the cyclone in my house
All I have to do is turn on my PC, why do we need an episode?
To quote a comedian: "It's not _that_ the wind is blowing, it's _what_ the wind is blowing."
They are forgetting that you have a lot of stuff that fly around inside the house.
This is a proof of concept, and also not the full episode. This is just for wind, later in the episode they decide that it’s not safe due to the debris
Open the windows during a hurricane, and see all the rain get in, and all your belongings go out.
Yeah open all the windows during the hurricane so that everything from inside your house flies out
I love the MythBusters(I'd go out with the bald guy in the white shirt anytime). One of my favorite episodes is the Explodibg Water Tank!
Suddenly everyone is a structural engineer
But all the rain will go inside the house
The destruction due to the wind is increased if the building has an opening, If the opening is at the front, then the pressure within the building is increased and this intensifies the external suction on the back, side walls, and the roof. If the opening is on a side wall, then the opposite effect occurs. Air will be sucked out of the building, lowering its inside pressure, and intensifying the pressure acting externally on the front of the building.

And please just close your windows unless you all want to get soaked in rainwater inside your cozy homes.
The furniture would just get ragdolled around...
Now you have to deal with a pool of water inside your house
pretty neat but all houses have different window placements and shapes,then theres water and stuff blowing away
"open windows during hurricane" good luck cleaning your stuff in house XD everything will fly
I know I could design a house to survive a tornado, and build a house that could survive a hurricane, just need to design them and I suck at drawing.
That is assuming your house even has windows on all sides of its structure. In which case, it may be potentially better to keep the windows closed regardless, depending on the situation.
That and you have to consider water damage as well. Still, water damage, if dealt with relatively soon after it happened is still better than no house at all.
Make no mistake, the hurricane will open your windows for you if they look like what's in the thumbnail.
If the stress is so bad the windows would brake before the concrete
watching this before a super typhoon (200 km/h - 124.274 mph ) hits our home in 12hrs...
Never seen a house with 4 windows that are basically the size of the house… or one with a flat roof.
Thanks!
then also not sure if letting wind blow "clean through the inside of the house" preserves things inside of it.
I stay in a burrow so no problem for me
Yes, but all the objects in your house get wrecked. All of your expensive gadgets, TV's etc.
this all assumes the wind will come straight from one direction directly at the side of the house, and that you'll have giant windows that are straight across from each other with nothing blocking them, and that some how with windows that size the structural integrity of the house wouldn't be severely compromised and wouldn't negate any effects of the large open windows.
The conclusion that is for houses that are tiny, made out of metal, and have giant windows.
For a standard wood built home It is likely the stresses around the opening would be so great that it would break the wall apart, keeping the windows open would probably increase the likelihood of the house being torn apart.
Regardless, because of the rain and debris in a hurricane, leaving your windows open is a bad idea.
Grim187 its weird to hear someone talking about a "standard wood build home" xD
Well, there goes my sofa....
I’ll rather have a giant insurance payout
If only my windows where that big.
That might cause less damage on the house but what about the inside of the property, anything not tied down would be trashed also most houses are not allied to let the air out in such a way.
What about the inside of the house? And when there is hurricane, there is usually rain too
I swear, the more I watch old science tv shows, the more times i realise they are using the soundtrack from the game Trespasser Jurassic Park XD
Thanks observer...got it! 💜😇
Agree Princess..good job! 💚
Well structural damage will be minimized but anything on the inside will have wind and rain damage
Living in Puerto Rico and Miami, FL for almost 50 years I've been through a lot or hurricanes. I'll keep my windows closed.. tks.
As every single thing in your house flies out those windows...
