Will Unloading Birds From A Truck Make It Lighter? | MythBusters | Season 4 Episode 9 | Full Episode

[@chriswatson6231]

The difficulty flying the helicopter: Oh the days before drones

[@greywhite2903]

You should watch some of the heli pilots during rally racing. Those guys are nuts

[@KandiKlover]

Quadcopters aren't drones. They're just multirotors and only called droned to mass market to low IQ fad boys like yourself. Also they fly more precisely and better than chinese DJI junk if you actually have the skill.

[@KandiKlover]

The better pre-Fad era. No NPCs.

[@itslegiTim]

14:23 not gonna lie, I laughed so hard when He just RAMMED the boat into the pole by hand 🤣🤣🤣

[@gohawks3571]

It makes me laugh every time 😂

[@KandiKlover]

Easiest $10 he ever made.

[@richphoenixpa]

my only problems on the boat myth was if you watch the impact... the boat doesn't turn. the front wheel hydroplanes and still is going straight. the second issue is that water acts a lot different since the boat would have to push against it to deflect. if the boat was turning into it and the water countered the deflection... it might still split. maybe not at 25 mph but much higher. so technically it's still busted.

[@Dalton1294]

The build team did retest the myth in water in a episode from the 2013 season and re-busted the myth

[@jbostudios]

If the cops asked me how fast I was going when I almost split my boat in half ……. I would also say 25 mph 😅

[@SirSaladhead]

Lol Adam left Grant hanging at 40:56 Sad to see

[@amusik7]

I wonder why not just place the boat at an angle on top of the trailer? It might not travel super straight but you would surely get it to impact at an angle.

[@themauler1599]

One of the reasons why the large scale boat crash didn't work is because the turn doesn't do anything to change the impact. When Tory rammed the boat by hand, the impact came in at an angle because he was moving the boat diagonally. Turning the boat via a wheel does change the direction of the boat, but the velocity and the boat are pointing in the same direction. At the moment of impact the turning boat and the straight ahead collision are nearly identical. To change that you would have to literally shove the boat with a huge force horizontally. Since boats, and most vehicles, aren't designed to suddenly juke perpendicular to the direction they're facing, this would never work. You'd be much better off lining it up for a head on collision and hoping that you've perfectly aligned the point of the boat with the curvature of the pole. Option B would be to create some crazy strong towing cable that whips the boat into the pole because turning your wheels 90° would just cause it to flip and fail. Of course the other reason it failed is because 25MPH was a huge lie, or the guy made his own speed boat out of aluminum foil and hope.

[@MeepChangeling]

IMO the boat in the photo was likely tossed via a wave and hit the pole due to that, not its own power. I've been in boats about that size on some rough seas for fishing. Even small 2 foot high waves can REALY throw a boat that big if you hit them weird. I can remember the bottom of the boat undulating and making sounds like a hammer as it smacked into the sea after getting lifted out. If we'd hit something solid, that boat would have been damaged for sure.

[@themauler1599]

@MeepChangeling that is true, the photo shown didn't really give a lot of perspective on the original incident but an unfortunately directed wave could have thrown the boat in a different direction and given it more force than 25 MPH on any speedometer

[@classicalextremism]

The big issue was they assumed the water surrounding the boat was a non factor. The water along the sides prevents it from bouncing and turning like their air straddled models, and there is a column of water behind the boat that pushes it forward adding to its momentum. Just do a sudden power down on a boat and the tail end will pick up as you get pushed forward by your own wake. Striking the pole nose on would be more likely to make the boat roll than skid. You have pressure in on one side, and a vacuum effect on the other. Depth under the keel would also be a factor in shallow water.

[@fireballninja01]

honestly like, 25 is a very Useful speed to be going at. Perhaps the dude from the newspaper article was going a lot faster, but in a residential area or some sort where there was a speed limit of 20, 25, or 30 miles an hour, meaning that he lied in order to not seem culpable?

[@fireballninja01]

the only other thing would be how much is in the rest of the boat. if the boat is packed to such a brim that 25 miles per hour is a hell of a lot more momentum/inertia, that might do something

[@srf2112]

They got it totally wrong thinking the boat bifurcation test would be identical on land. The part of the boat partially submerged in the water would be held by the water somewhat helping to prevent the boat glancing off to the side so easily.

[@jarehelt]

Why would a load of birds be overweight in the first place.. 😅

[@alexbouchard3880]

Very fat birbs

[@alexbouchard3880]

Very fat birbs

[@sometimeclown5281]

BIG nostalgia watching these episodes!

[@OliverBelmont-g5b]

if I hear the word bifurcate one more time I’m gonna make like a banana and bifurcate lol

[@apeaape]

Thanks Banijay. I like this episode

[@kadehudson116]

I the Jamie was actually with them in (15:00) 🤣

[@johnehett2499]

About the boat. I may have missed it but I did not hear them talk about the force the water would create towards the pole due to a boat with a v haul is ment to cut thowe the water like a track and that's why when you turn from rear of boat it urns as if on a front pivot so when the boat hits the pole in the water the force towns the pole from the fusalodge wanting to go strate would add forec to the accident and in the direction of the pole reducing the boats turning out apon impact so to do the experiment justice one would have to do it in water or find out the amount of force the water creates

[@jacobpettes335]

If the hull was brittle enough that the initial impact could open a crack all the way up the middle then this might work. Without a crack opened, the blunt pylon has to force itself through several feet of fiberglass, which would take thousands upon thousands of pounds of force. They would have to nail that pylon at a very high speed to get that result.

[@BestowalPants90]

40:43 anyone else see the bird on the right get pile drived by that pool noodle lol

[@ConLustig]

Okay buuuut if you’re transporting a large number of birds you’re probably driving a poultry truck and a traditional poultry trucks have a lot of ventilation so ..if they are getting some lift from the air flowing through the truck that is not necessarily exerting downward force in a closed environment…maybe???

[@stephenkamenar]

should've showed that if you pickup something in the truck that the weight goes down (pickup with a long arm outside the truck). not that that's necessary but would be nice to see the sensors working

[@evandaymon8303]

Myth is the object has to do the decrease of weight without aid. That would not prove myth to be true because it has help from outside source.

[@skatergunny]

That boat myths setup was terrible

[@ChristopherHillman]

I'M Surprised...making a scaled down Boat ... BuT didn't scale down the thickness of the hull? ... (the modem was equivilent to replicating a full-sized boat with a 6inch thick hull)

[@Apoplexy18]

Crazy to see that at that time drones not even invented jet :D

[@skyraider87]

No, they were a thing. They just couldn't get a small enough camera while maintaining decent camera quality. Drones aren't a new thing, drones with good cameras are

[@gray5504]

Surely they just tell the myths, right?

[@RustyShackleford108]

They don't.

[@-.._.-_...-_.._-..__..._.-.-.-]

They put them to the test.

[@bannedcabron]

Maybe they should try to fly the drone/'copter with open slats at the bottom of the trailer so the downward wash would escape outside the envelope to open the system to that and, maybe, turbulence by outside pressures.

[@bannedcabron]

Oh, yeah, the trailer can't be hermetically sealed lest the live birdies parish, so the pigeons could still fly and the pressure could still leak out.

[@thebigpest2138]

what you are missing in the boat test is water pressure on the opposite side of you contact point. it might have made a difference. 😉

[@alexbouchard3880]

I wonder if the trailer was open and the helicopter flew away at what point would the weight go down

[@FranksBellyGod]

i was thinking the same but if the floor had holes where the force can escape would it make the trailer lighter

[@johngamer6255]

It looks like when the boat did the turn, it understeered, though, and tbh I don't know how you'd fix that

[@Jeremy-ot6pb]

why didnt they use rails instead of a cable for the boat

[@kennywise1]

Donzi wow… best speed boats you can get in my opinion

[@bruceforsman4812]

poor little taco hauling over sized trailer

[@F_L_U_X]

4:05 just flick the window, could've saved a lot of time

[@FreejackVesa]

They're testing small scale options in order to design their large scale. They can't just flick the side of a truck with 100 birds in it.

[@Kr-nv5fo]

No wonder the insurers hated them. They didn't even wear life preserver vests for a speedboat ride.

[@jpdemer5]

How is that even a question???

[@lewismaclean8849]

I would love if you can upload the episode where Kari, Grant, and Tori test various hollywood car crash scenrios.

[@gagemeyer363]

The boat in fact did not turn on land

[@peternjoroge508]

With water you would have less deflection on the boat so this is highly unscientific

[@skyraider87]

Its a TV show, give them a break

[@graceybfrg]

No mph at sea, knots baby

[@shizo_n01z3]

Repost?

[@michaelmayhem350]

The show is 20 years old....

[@soundtrancecloud5101]

2:36 the meth lad is in the basement lol

[@peternjoroge508]

What if the truck has holes at the bottom?

[@stephenkamenar]

"my boat didn't split, must be impossible for any boat ever made to split, busted"

[@UNOH_Blitzkrieg]

Peda is not happy lol I am tho

[@SonOfGalactus]

Using an rc helo in place of the birds, i forgot how off they were sometimes...

[@ice-mann]

Is Adam Savage related to Randy Savage the Machoman?

[@MGower4465]

Since that isn't the late wrestler's real name, no.

[@DaniTheNachoPirate]

I feel like the weight of the small scale chamber was unaffected due to the helicopter being attached to those tiny rods which were grounded to the chamber.

[@MiloLego716]

They were just guide rods (rods attached to the helicopter slide into open tubes on the floor). Just keeps it centered, doesn't attach to the base

[@krokodil191]

Do we really have new episode?

[@briarstichbury2815]

This was on TV when I was a kid

[@michaelmayhem350]

It's 20 years old there's no new episodes

[@krokodil191]

You really dont get it, do you?

[@jacobpettes335]

When the birds stand in the trailer, their feet have friction with the ground, transferring their weight directly to the trailer. When they fly, the air has no friction against the ground and just swishes around. It should weigh less than before, but not enough to make an overweight truck become safe.

[@TJ-nr9cg]

I could've saved you tons of money on this episode just using common sense and 5th grade physics.

[@MiloLego716]

But that's no fun ;)

[@FreejackVesa]

Well excuse me, Einstein. This was a show for a younger audience.

[@IceInMaWeiner]

stop reposting the same episodes. just fix your channel link.

[@elkneto4334]

ofc it will make it heavier, birds are flying so they must be lighter than air... noobs

[@_invencible_]

aircraft are certainly not lighter than air, yet they fly. noob

[@majortom4543]

The birds were resting. They have a load.

[@MGower4465]

Might want to cancel that appearance at the comedy club.

[@TJ-nr9cg]

I could've saved you tons of money on this episode just using common sense and 5th grade physics.

[@madmanwithaplan1826]

And you wouldn't have an awesome TV show like they did so between the two of you I'd say they were way smarter, since they actually understood what an entertainment product is. Good luck with your fifth grade education though

[@jasontraxler8146]

17:15 confirms it, they knew, they just continued to prove it to the naysayers. Sometimes they did a myth even with confirmed answers just to educate the public.
