The Krummlauf basically worked and it was not that much of a problem that the bullets turned into shrapnel. It was basically intended for short distances, for example if you had Russian infantry climbing on your Panzer you could hose them down with a 30 round magazine fired from the StG44...
Correct, when the target is 100 feet or less away from you it is not a huge deal. At that range the bullet breaking up might help you out in deterring an attack by getting a shotgun style splatter effect.
the curved guns were invented for tank crews, in order to defend against sappers mining or climbing the tank. and they were pretty effective. the intended range was like 2 meters. also used in bunkers to relatively good effect. the periscopes were useless and usually got thrown away.
There's a reason a lot of r&d went into the curved barrel, bending it can cause it to narrow, so they'd have to compensate, forgotten weapons a little while ago featured a bullpup under over shotgun with curved barrels
@@tenofprime the bullet is shaped in a way that forces it to travel forward, in one direction, as quickly as possible. Therefore there is no way to change a moving bullet's path and keep it fully intact at the same time.
@@abelsm6270 so you're seriously trying to convince me that bullets have a narrow shape in the direction they travel? I don't buy it, bullets are obviously short and wide, and only work when shot sideways
The large sound mirrors had microphones in the center, their main failing was that you couldn't tell height or direction, aside from if it got louder it was coming towards you, quieter going away!
For the cement ears, actually the chain home system that was later used for the radar towers was actually developed for the cement ears and they just re-purposed them after radar came along.
6:13 That's actually not too far off. They have the same shape as satellite dishes (a paraboloid) because they're both parabolic mirrors (this is an acoustic mirror, and satellite dishes are radio mirrors), which reflect all rays parallel to their axis to a single point, called the focus, where a receiver is located. You can see these acoustic mirrors in science museums nowadays.
The point of the horse powered train is mechanical advantage. A horse can only pull so much weight, but if you hook that horse up to a gear system you can apply mechanical advantage to pull a vastly multiplied weight at a cost of acceleration.
Quick question, Mr Terry: ever considered checking out OverlySarcasticProductions? I feel like Blue's (Gregory Kerr) vids on historical topics would be right up your - and the channel's - alley.
Those Acoustic Mirrors are pretty awesome. At the local Science center they have a pair set up across the food court area, and in a recent trip (I had not been there in over 10 years) they were still there, and my kids and I had some fun with them. You can, even with people walking between them and all that noise created by them, literally whisper to one another and still make out what the person is saying across about 100+ feet of noisy cafeteria bustle. (on a side note MEIN GHOT! that had me laughing for about 5 minutes solid.)
there's a device called "corner shot" which was developed in 2003. it has the same functionality as the krummlauf (but with higher success rate and different technology)
Kinda. Not the entire gun, the idea was closer to giving a machine pistol a bendi-rifle shaped stock. You only put the barrel/hammer and magazine around the corner but not the two handed stock you held on to safely out of sight. The rest of the gun shaped stock was for the electronics and camera etc so you can aim.
Shawn Woods actually built that mouse trap (plus hundreds of weirder, older ones) in a video, that’s where the black and white photo of the trap came from.
the krummlauf wasn't a failure. it wasn't made for "shooting around corners" it was made for tank crews to defend against infantry trying to climb the tank, the bullets fragmenting inside the bent barrel was by design as that, combined with it being on a submachine gun, generated a stream of shrapnel that would be lethal enough at close range and the low durability wasn't an issue as tank crews weren't supposed to even get into that situation.
I saw that pistol mouse trap from Shawn woods channel. He didn't load the gun, but the trigger system actually worked quite well and since a blank is enough to kill a rat I don't think it is as dangerous as it seems. But I guess even a blank might start a fire or something.
8:00 Strange enough that it in fact worked. The Mythbusters tested it. germany used them, if I remember correctly, to shot allied off and around their tanks from inside, or when they were pinned to a corner. Surprisingly the bullets didn't broke apart,but came out normaly.
Some time ago, I found a YT channel named Overly Sarcastic Productions (Mostly shortened to OSP) half of their channel is about myths and classic books, and the other half is about all things history. I think that channel may be something fun for you to make videos about. Have fun
A children's interactive museum in my city has a pair of acoustic mirrors. They are on opposite sides of the main floor on stand with a ladder. You can have a whispered conversation between both mirrors. A old device was an acoustic detectors for detecting mining in siege warfare. They made a bronze, or brass diaphragm them mounted it on a shaft that was set deep into the ground. The shaft would transfer vibrations from mining to the diaphragm creating sound.
The Acoustic Mirror is the only thing I had heard of before, thats only cause the local (well local-ish for being a two hour drive) science museum had them, had a blast saying a bunch of naughty words and insults to whoever happened to be on the other end
Can you tell me more about the display or what museum it's at? I'd never heard of this before and I'm fascinated lol would love to replicate it on my land someday for fun
@@ItsAsparageese It was at the science center in St. Louis, Missouri. Though its been over a decade since I was last there so I couldn't tell you if they are still there. The center had two Acoustic mirrors set up outside spaced pretty far apart and pointed at each other. You could talk into one and hear what was said in the other.
Why does Mr. Terry look like a grown up version of a middle (primary) School bully that you would see in a early 2007 movie that halfway through the movie becomes friends with the main character?
Often overlooked detail about the Krummlauf, it was ment for full auto weapons like the STG44 to be used inside tanks to kill infantry trying to mount the tank and preventing them from accessing the hatches. Which kinda goes to show how well tank combat was going for Germany, if that was a major concern
My hometown is Austin, TX. One of those still extant Moonlight towers now gets tricked out as a Christmas tree every year. Some kid that wins a coloring contest gets to press the button to light the thing up.
Yeah I would religiously watch through and take notes on a series of reacts to every Extra History episode, or even like special long overview reacts where he covers groups of EH episodes at a time or whatever. They're a great series-of-serieses and I love the context and framing that Mr. Terry adds to everything. It really helps the info stick for me.
The revolver mouse trap actually works. I've seen a channel that shows different mouse trap designs and even tests them out. The revolver the guy had was unloaded, but it shows it does function as it should.
This sound amplifiers actually work fundamentally the same as a sattelite dish only with sound waves instead of em radiation. The dish focuses the waves at a point a little away from dish. If memory serves that little arm thingy on sattelite recivers is itself the receiver for those waves bouncing off the dish.
The bendy rifle thing has been resurrected as the "CornerShot." It's an articulated rifle stock you can clamp a pistol into, with a camera looking down the sights and a screen for the wielder to look at.
Bent barrels on firearms were usually used by tank crewmen to kill people climbing on their vehicles. Didn't have to be accurate as its close range and full auto.
One other thing about moonlight towers is that the didn't require Edison's bulbs. You could use arc lamps, limelight, or any similar high power source.
Those "acoustic ears" had a display, of sorts, at Iowa's old Science Center (before the new one was built). They were several meters apart, and all you had to do was go up and talk to it, and the other person could hear you with perfect clarity. They blew my mind as a kid. I remember the other kids having a blast with those-who needed cellphones with these things around? XD
One really funny story I read once was about a time the Romans were besieging a Gallic fortress and they started building a siege tower. The tribals laughed and taunted them the entire time, until the siege tower was finished. The Gauls saw the giant tower moving towards and immediately surrendered to the Romans. They believed there was no way the romans could have moved the siege tower by themselves and assumed that they had received help from the gods.
Cheaper to build than a steam locomotive, but vastly more expensive in terms of upkeep, has much longer and more frequent downtime, uses more types of resources, and lacks power to boot.
The thing with the Impulsoria was that it had gears. Due to their anatomy and body mass, running exhausts a horse rather quickly - but they can walk almost endlessly. Work (in this case, literal horsepower) is the product of (mass x distance)/time - specifically, 33,000 foot-pounds per minute. Moving 3000 pounds @ 11 feet per minute or 300 pounds @ 110 feet per minute is the same amount of work. Coupled with the fact that railcars have less than 1% the rolling resistance of a wagon on the street, the impulsoria could operate at speeds comparable to modern light rail systems! (Also without the noise and pollution of a locomotive.) Not bad for 'primitive' technology.
"Work (in this case, literal horsepower) is the product of (mass x distance) time" that's not work, that's literally power. Work is just force times distance(assuming a a straight path and constant force).
7:42. Those were used by German tank crews to defend their tracks from close infantry while still being relatively safe at the hatches. Accuracy wasnt much of an issue as it was mainly shooting and suppress fire to get them away before they can plant demolition charges or other explosives
