Love this episode. They did build a boat out of pykrete during the war on a Canadian Lake. Operation Habakukk (or something like that). Took a whole summer to melt. There were several reasons they never went full scale. One was the amount of wood pulp needed to make a "berg-ship" would threaten the production of books and newspaper. Another reason was that each ship would have a massive refrigeration unit built throughout it in order to keep it cold and the amount of steel needed for that was similar to the amount needed to build a regular warship. Might as well use the steel and build regular ships. Another reason was the allies got permission to use various islands such as the Azores so they didn't need massive floating islands. Plausible but impractical.
But also by the time the prototype had been build the U-boat menace had decreased quite a bit. Also you had more long range land based planes and the US was making escort carriers at a rapid rate. Escort carriers are one of the unsung ships of WW2 as they never got quite as much attention as the big fleet carriers. However for the cost of 1 fleet carrier you could make about 5 escort carriers and they proved invaluable in convoy protection and to support fleet operation. Escort carriers are still around today in a way with marine assault ships.
The idea of a huge torpedo proof slab floating around the north Atlantic as a floating air base is quite a fun one though. Effectively to fill the air cover gap in the Atlantic that existed at the start of the war. Very impractical, but I love some of the mad ideas that came up in that era
Mythbusters get out of scale in the Pickerite test. In 1944 a "small prototype" was build. The "small prototype" was a 1000 Tons ship, not a 3 tons boat, and was successful enough to plan a 2.000.000 ton carrier (almost a small island) with a 12m thick hull, to close the Greenland Gap. Melting it´s a surface thing and it´s affected by the cube-square law.
@irishnovember5900 well it does have some uses. Not really now with technology but when my great grandfather was a boy they would have to make there own freezers in the mountains. They would start with digging a hole or finding a small cave fill the bottom with wood chips and sawdust and would build a shelter around it and would lay ice they got from the lake when it froze during winter and would keep that ice in those shelters during the summer and it would last also along with having ice in the summer it also kept things inside cold
@@irishnovember5900 the cost of 2 million tons of frozen sawdust would be a lot less than 2 million tons of metal... plus in a time where metal supply lines were bottlenecked and any additional military resource was desireable it made perfect sense to try radical alternatives... even just 1 more aircraft carrier can dramatically effect a naval war. and this was a promise of a parallel production line that wouldnt compete for materials with any existing ones.... ofc being as impractical as it was it went tits up... but the reasoning was sound.
The pure amazement of seeing what he thought has a sure bet, socking it with a lot of load applied and the composite just shrugging it off. It was a well deserved Jamie smile.
The one advantage of pykerete was it was torpedo resistant. The one built in Canada in 43 was torpedo'ed several times to test and apart from a few 6-12 inch deep dents it was OK. The plan was to park it mid Atlantic as a stopping point and to provide protection againnst U-boats
Or used a Fiero. I don't think any front engined car would split due to the engine and transmission being too dense. But a rear engined car may split, til it got to the engine anyway.
The goodish thing about a wood/ice boat is you can sail it into enemy waters, land on their shores and it will melt and be taken by the tide almost as if it wasn't there in the first place
Pykrete is always going to melt as long as it's in liquid water (above freezing temp), unless you have some sort of cooling system that helps keep the hull frozen
I think the only thing their boat is missing is mass. If you made an entire battlship out of this newspaper stuff and made the middle also solid ice it could last pretty long. If you connected the outside and inside with some copper wire or stuff like that, to spread out any heat it could be pretty cool. Then it would take longer to melt from the outside.
Both of these 1980's cars have steel frame chassis' with steel engine blocks and centre-line transmissions and driveshafts with solid rear axles. Modern FWD cars with aluminum engine blocks, no frame chassis, and no centre-line driveshafts or transmissions might yield significantly different results.
i like how with the very short clips they show they try to frame it as an american invention lol its very much a british invention tested on a canadian lake i believe
Pykreke probably works like concrete. The glue in concrete is cement and cement is a very good and tough glue but it has the same problems as most glues: It sticks well to many things but not to itself. A thin layer of glue can form an almost unbreakable bound but fill the same glue into a mold, let it dry and then try to break it apart and most glues will break easily. So to avoid that cement only sticks to other cement, you add some sand or stones, that way the cement can stick to the sand and stones, only filling up the gaps in between them and that leads to a way stronger bond. The same is possible with super glue. Super glue is very strong, a single drop of it can hold up to 600 kg in place but if you fill a larger gap with super glue, it won't be very strong, as super glue does not stick well to super glue. But when you first fill the gap with fine grained plastic powder and then pour super glue over it, the glue only fills the gaps between the powder and this bond will be extremely tough.
That isn't true though. Water does stick to itself, it's one of it's defining properties and why it's essential for life. Hydrocarbons also stick to themselves which is why life is based on hydrocarbons and water. Ice is actually extremely strong but the problem is that when it freezes it expands and forms all kinds of cracks and voids which means it can easily break. If you freeze ice very slowly layer by layer it actually is extremely tough. Pykreke works by filling up the voids that would form with ice as the ice will bond to the fibres.
@@MrMarinus18Cement and glue also sticks to itself, but not as good as it sticks to other materials. I can break a large chunk of ice apart with my bare hands but I cannot remove a thin layer of ice frozen onto my wall without damaging the wall.
LOL Banijay is not some youtuber that happens to upload random mythbusters video on his channel. This is a multi billion french media group, that owns the owns the rights to mythbusters through one of its many media companies.....
The pykrete isn't a myth they actually tried and worked, the prototype, the problem was it was to massive demanded to much resources and eventually it was pointless as alternative methods eliminated the need for such a thing
If you live in California all your life I guess you do drive at 55m/h in extremely poor snowy weather 😅 Last snow storm it took me 55 minutes for a 20 minute ride home, Though it wasn't that cali snow, so I don't know 🤷♂ maybe we are both just pussies that don't know how to drive in near zero visibility at high speeds.
Speed is too low, 55mph is just for one car. If snowplow travels at least 40mph per hour, and car 50mph then compine speed would be 90mph, So just 55mph could not cut the car.
That is not how physics works. Add the total and then you have to divide. Otherwise both vehicles would experience a 90mph crash. Times two, is 180. Newtons law etc.
At least it's free. You won't find that episode in any streaming service. Gladly, it's on TH-cam. Switch sound to mono, and it should be good to watch for you.

They don't tell you that thesnow plough blade was fabricated by them as you can see by the lack of welding along the vertical egdge of the blade which shoud be welded along the complete seam and there shoulkd be no rivets at all

The frozen newspaper boat work very good for the fact is made of only newspapers. Sad they dont use the original Pykret.

yeah but even then...it's a dumb material. It makes no sense. There are no benefits to using it in real world applications.

39:00 what they actually could've done is to try the car with no engine at all. the thought about it will not leave me alone

Looked to me as the thing rose up then stopped that the rear axle stopped the cleaving.
That boat left a paper trail... :D

I wonder what caused the lights on the rear of the car to light up for a brief moment 26:36

They should try replacing the water with varnish, or epoxy! Then test it's effectiveness to boat making.

Was Tory wearing his shirt inside out or was the logo supposed to look backwards?
15:20 Adam impersonates Rick and Morty, about 5 years before R&M aired. What a legend!

isn't "super pycrete" just basic micarta but using ice instead of resin?

Well, the engine produces heat
But the melting didn't start near the engine, though.

@svampebob007 honestly I'd prefer to arrive 10 mins later and alive then be in a crash, I'm a nurse so I've seen the damage crashes do.
Muito show
Only thing i could see wrong is the cars are american heavy steel try a Japanese car from the same era
Documented weak steel and smaller transverse engine you might be able to actually miss the engine and still hit the middle
And it's a 4x4 car with a solid front axle that thing isn't going to cut unless your going a lot faster
