ฝึกพูดภาษาอังกฤษด้วยเทคนิค Shadowing จากวิดีโอ: These Dumb Weapons Actually Existed
กำลังสร้างบทเรียน...
1
Dumbest weapons in history.
2
War between humans is bad enough, so it gets rather depressing when innocent animals are dragged into the mix.
3
But honestly, animals have been used in warfare for ages.
4
War elephants, attack dogs, carrier pigeons, bat bombs.
5
Wait, bat bombs?
6
Yep, bat bombs.
7
Just one letter off from being a very nice, relaxing evening, the bat bomb is anything but.
8
Dubbed Project X-Ray, the bat bomb was an experimental weapon developed by the United States for use against the Japanese in World War II.
9
Initially thought up by a friggin' dental surgeon, no less, the bomb would work like this.
10
You stuff a bunch of angry bats into a little canister.
11
Mexican free-tailed bats to be specific.
12
Why?
13
Well, because they're small and cute, that's why.
14
But they're also very fast, which is probably way more conducive to the task at hand.
15
These flappy boys can soar through the air at around 100 miles per hour.
16
Okay, fast bats.
17
Cool, got it.
18
But how were they bombs?
19
Glad you asked.
20
There were actually little bombs just straight up strapped to their chests, of course.
21
Each bat was equipped with a tiny 1 ounce incendiary device, which was just a small pouch of napalm that would detonate after a timed delay.
22
So, now you have your explosives.
23
Just cram them all into a small capsule and find a target.
24
Easy enough, right?
25
Once the bat bomb was dropped over an intended target, a parachute would deploy, opening the bombshell, and releasing over 1,000 bats.
26
In theory, the bats would scatter across the landscape and look for places to roost and go sleepy by.
27
Anywhere that a bat could squeeze into and honk some me-me-me's was a suitable target.
28
Since the bats would likely spread over a wide range to multiple targets in the area, they would prove to be very effective little terrorists as small fires would spring up across the city
29
and be difficult to contain.
30
So how did it do?
31
Well during a test run in a US airfield hundreds of armed bats were accidentally released and took refuge next to,
32
for perfect comedic effect, a giant friggin fuel tank.
33
Don't.. move.
34
Though effective, Project X-Ray was cancelled because World War II ended before testing was fully complete.
35
Maybe next time, fellas.
36
Nuclear bombs dropped from the sky are pretty cool, but how about a bomb that you could bury in the ground, waiting for victims to roll over it?
37
Like a land mine?
38
Yes, like a land mine.
39
But a bigger, better one.
40
Enter the Blue Peacock Nuclear Mine.
41
by the British in the 1950s, the goal of this bomb was to stop potentially invading Soviet forces from taking over recently war-torn Germany.
42
You know, if they decided to do that sort of thing.
43
Oi bruv, you want Germany?
44
Well, come on then.
45
Oh, I ain't gonna tick.
46
Oh.
47
Yeah, come on then.
48
It was a great exit strategy to render the area completely useless as everything was now reduced to atoms and irradiated.
49
I can't have it, no one can, said the British.
50
Though to level a whole city, these things had to be massive, and they were.
51
Each bomb weighed around 16,000 pounds.
52
The bomb would lie in weight underground to be detonated remotely if any invasion took place.
53
The problem with a bomb being underground and unattended is that a lot can go wrong.
54
Detonation mechanisms could fail and refuse to detonate, or it could detonate prematurely like a bad date night.
55
One particular concern was the preservation of the detonation mechanisms during the cold winter when the ground froze over.
56
So what would be a suitable way to prevent a bomb from freezing?
57
Well, you probably want some heat, but from what?
58
Heated water?
59
Eh, not practical.
60
Electric heat?
61
Eh, too dangerous.
62
Wait, I've got it.
63
Body heat.
64
No, Ron, get off the bomb, put your clothes back on.
65
Cool.
66
I'm talking body heat from this.
67
Yep, it was proposed
68
that live chickens would be stuffed into the bombs to provide enough body heat to maintain operation during cold spells.
69
They would be given a supply of food and water as they enjoyed their stay in the 5 star volatile vessel.
70
In the end, only two of the 10 proposed bombs were ever built, but neither were ever detonated, and the project was scrapped after a few years of development.
71
The Imperial Russian Navy was looking to revolutionize naval warfare in the 1870s.
72
The basic premise is that the bigger the guns, the better the navy.
73
Well, to have bigger guns, you need bigger ships, but when you build bigger ships, they could probably hold bigger guns.
74
But then why not just build even bigger ships to hold even bigger guns?
75
Well, it's not that simple.
76
By design, ships are rather narrow, leaving weight distribution pretty limited in a geometric sense.
77
So why not widen the ship to be more, I don't know, round?
78
Surely that would solve the problem.
79
No, that would just be a dumb design.
80
But Imperial Russia didn't think so, and thus in 1874, many, many Russian rubles were put towards developing and building...
81
The Novgorod.
82
This absolute unit of a warship measured 101 feet in diameter and was protected with 12 inches of plated armor.
83
Equipped with two 11-inch cannons, it was basically a fully strapped lily pad.
84
Any good warship is fast with reliable steering.
85
Was the Novgorod?
86
Nope.
87
By contrast, it was painfully slow and hard to steer.
88
At top speed, the circular ship cut through the waves at a staggering 7.5 miles per hour.
89
Slightly slower than the average male running speed, according to Google.
90
And funny enough, with its circular design, recoil from cannon fire would often cause the ship to unintentionally rotate,
91
slowing down any formidable suppressing fire in a warfare setting while the ship resets position.
92
Not that it mattered too much because each cannon took 10 minutes to reload between shots.
93
Despite her shortcomings, she participated in the Russo-Turkish War of 1877
94
but was ultimately used for shoreline defense instead of active naval warfare.
95
Her career was surprisingly long, lasting 29 years before being decommissioned and eventually sold for scrap.
96
Even today, the Novgorod is regarded as one of the worst naval ships ever designed.
97
The ship had many flaws, sure, but experimentation is how we improve as people.
98
Or at least that's what they tell us.
99
Ever have an annoying bug buzz in and out in front of your face
100
so you try to get rid of it by blowing some air at it?
101
Yeah, not very effective is it.
102
And neither was the wind cannon.
103
This 90 degree ass silly cylinder was almost one of the Nazi's Wunderwaffen or wonder weapons.
104
Almost.
105
It was a 3 foot diameter, 35 foot long cast iron cannon, and it worked like this.
106
A bunch of hydrogen and oxygen would be compressed into the cylinder, and if you paid attention in any chemistry class, you'd know that hydrogen is very flammable,
107
as the Hindenburg found out first hand.
108
Oxygen, while not flammable, typically makes fire bigger, so if you compress the two gases together and ignite them, you're gonna end up making a big kablooey.
109
All that air pressure needs somewhere to go, so it all rushes to the path of least resistance, which happens to be the end of this cannon tip here.
110
It's essentially a giant potato gun, but instead of a potato, it's a giant air bullet.
111
But how much harm could that really do?
112
Well, during tests, the cannon was impressively able to destroy a stationary,
113
one-inch thick board over 650 feet away.
114
Sooo it didn't really do much.
115
It proved even more useless against moving aircraft which fly several thousand feet high.
116
You'd honestly have better luck just hucking rocks at the dang things.
117
The cannon was only ever used in warfare once
118
when it was installed on a bridge and it didn't yield any significant results, which is why it's in this video.
119
Look at it.
120
Look how dumb it is.
121
Even the Soviets were in on the whole experimental weapons thing in World War II.
122
Everyone was really out there trying new things and seeing what stuck.
123
Take, for example, tanks.
124
Tanks are good.
125
They drive around on the ground and shoot shit, right?
126
Well, what if they could also fly?
127
No, no, no, not like an airplane.
128
Well, actually, yes, like an airplane, but only to make it to the battlefield quickly to drive around on the ground and shoot shit.
129
Previously, tanks were haphazardly airdropped with their crew dropped separately, and that's just too slow for warfare.
130
Enter the Antonov A-40 Flying Tank.
131
It's a tank strapped to a glider.
132
The operating principle is that these bad boys would already have their crew aboard while a bigger plane does the heavy lifting.
133
Once approaching the battlefield, the plane would just dump its load, releasing the glider to the ground below.
134
Once landing safely, the wings could be dropped and the tank could ride right into the heat of battle.
135
The tank used in the experiment was the Soviet T-60, a rather small light tank typically used for scouting.
136
But despite being classified as a light tank, the thing still weighed almost 6 metric tons or just over 13,000 pounds.
137
So it was far from light.
138
But how is this thing gonna fly, you might ask?
139
The answer is, not well.
140
In order to lighten the load and reduce drag, the tank's secondary guns were removed.
141
Headlights and peripherals were stripped, and ammo and fuel were kept to a minimum, rendering it almost useless.
142
In the end, only one T-60 tank was ever equipped with the glider wings and dropped.
143
When it was tested, the tank landed rather roughly, and 180'd back to base almost immediately.
144
Those overseeing the project were all, Hmm, this tank cannot fly good.
145
And the project was immediately abandoned.
146
All right, there you have it.
147
A bunch of us- Don't forget the gun.
148
Wait, what?
149
Oh yeah.
150
Um, yeah, I've got one bonus for ya.
151
Roll it!
152
As an honorable mention, we have the Krumlauf, which will certainly make you lauf your ass off.
153
This is a German weapon attachment used to theoretically shoot around corners, but would you be surprised if I told you it was extremely ineffective?
154
The barrels would only get through a few hundred rounds before just destroying itself.
155
Not to mention that the bullets would be shattered into fragments upon exiting this curved monstrosity.
156
Imagine the last thing you see being a weird curved pipe
157
coming around a corner before your melon just gets converted into jelly jammed by Hans' Looney Tunes ass gun.
158
I'd be pretty irate.
159
Not that my face could express it.
160
Alright, now I'm done.
161
But you're not done watching, so click here to watch more.
162
I'll see you over there.
