Gav:
Today, we’re near Uvalde.
I’m about to fire a tank. Fire! – Oh!
– Whoa! Gav:That was intense.Dan:It blew me away.It’s outpacing
that shockwave. Dan:Oh, there’s a shockwave.
You can see the shockwave.
Gav:I think that’s
some of the coolest footage
I’ve ever seen.
What is this?It’s my baby. Fire! It’s an absolute war zone. ( exhaling ) Well, that was, honestly, some of the most insane
high-speed footage I’ve seen. I think my brain’s just
about recovered from the shockwaves of that. – It was loud.
– It was loud. The D20 was loud. Three, two, one, fire! Did you hear that? That was one of my most fun
days I think, actually. – Yeah?
– Firing a tank is awesome. When I was a kid
I always wanted to know what it’d be like
to be in a tank. So we’re inside
the Sherman right now. It’s pretty cramped. It would have
five people usually. You got the driver
and the co-driver. You have a commander,
the gunner’s seat, and you’d also have a loader whose only job
is to load the gun. This here’s the breech,
which is where you’d
load the ammunition in. So you have to punch it in
with your fist and quickly remove your fist, ’cause this part
will come across and lock in and then you can fire it. I can’t imagine, especially
with five people in here, what the change
in pressure must be like when this thing’s
getting hit or shooting. Actually being
inside the tank, you get much less of an effect
when you’re firing it. It doesn’t feel as beefy. Because you’re outside,
you have all that pressure. Whereas inside,
you don’t really, ’cause you got that
breech protecting you, and you got steel
all around you. You know,
people overuse the word, – but it’s awesome.
– Yeah. – It’s very cool.
But how do you drive it?
– Yeah. – There’s no wind screen.
– That’s fair. Is there a steering wheel?
Like, what’s going on? I actually would–
I have no idea. What even are the controls?
Pedals, buttons, levers? – Yeah.
– I just assumed it was
a thumbstick – kind of controller.
– Of course you did. So we took
the opportunity to learn
how to drive a tank. I’m up in the tower. Okay, I’ll try not to crash
or do anything too rash. Yeah, try not
to bend the thing. All right,
so to start it up,
just click it. Down, yep. Very satisfying. We’re gonna
be heading toward… Yeah. Yeah. ( man laughs ) Perfect. A little shopping– No. Okay. Is it fun to drive? It’s pretty cool. – You just have
these two levers.
– Think I could drive it. – I think you could do it.
– Yeah? I think that even though
you can’t even drive a car, I think you could
drive a tank. – Don’t have a driver’s license.
– I think it’s easier. Well, now we all know
how to drive a Sherman tank – in an emergency.
– Or a zombie apocalypse. Or a zombie apocalypse. Next up, to help us learn more
about how a tank works, we have an ammunition
technician. – Dan.
– Hello. – Thanks for coming on.
– My pleasure. What could you tell us
about the tanks
that we were in? Well, the one we just drove,
that was a jumbo. There was only 250
of them ever made. And you run us through
what actually occurs
in the tank when it fires? I can.
This is the projectile that was fired
by the tank itself. It’s about 15
and a half pounds. Can’t really relate to that. – It’s over a stone.
– Yeah, it’s the equivalent of three whole bags of flour. What would you rather
get hit by? This or three bags
of flour? Well, I mean,
probably this, but at that
sort of speed, either one would
probably do some damage. That would just
be a lot more dusty. – Yeah.
– Poof! So what happens is, if I lay it down
on the side here, imagine here we’ve got
the cartridge case. What happens
when you fire the tank when I was pulling
that little string, a firing pin was impinging
onto the primer and that was igniting
the propellant inside the cartridge case. That propellant
is hitting the base of the projectile here. You see this part here?
This is called a driving band. This is copper. – So this is softer.
– This is softer. So if you look down
the barrel of the gun, you’ll see the rifling
like twisting grooves. And because this
is slightly wider than the projectile itself, the copper engages
in the rifling
of the barrel. And that then imparts a spin
on the projectile. So this little strip
is the reason
it’s coming out like this. – Yeah. And I’ll show you
what I mean.
– Okay. This is one
that we’ve previously fired. – Obviously–
– Can you guess
which has been fired? Yeah, we dug this
out of the ground and you can actually see these
individual grooves here are the copper that have gone
through the rifling there. This engages in the teeth
of the barrel and then causes the projectile
to spin when it comes out. Every ten inches
it travels, it’s done
a complete rotation. So to clearly illustrate
what I’m talking about we can just see
the footage. This is my favorite shot. Gav:So almost as it travels
the length of itself,
it’s coming round
on a full rotation.
– Dan:Yeah.
– Gav:So if it wasn’t spinning,that would just be tumbling
through the air.
And you can definitely see
the rotation from the rifling.
Dan:It’s like
an American football.
When you throw one,
you spin it
and it stabilizes in flight.
Yeah.So, obviously,
1,700 feet per second
is faster than
the speed of sound.

Yeah.Which is why we’ve got these
bow waves you can see
in the air.
We actually got very lucky
with the fact that this is, you know, it’s a gradient
from blue to a darker color.You can see it very clearly’cause you got two colors
coming together.
Which I’ve never seen beforewith, like,
naked eye, obviously.
That’s very cool.Holding it,
and it’s so dense. It’s like, wow,
that is seriously damaging. That one was 15 pounds, but the one we fired
from the 152 mil D20. Hold this. – There you go.
– Yeah. That’s a lot heavier. It’s about half
your weight I think. This shell actually
comes out really fast even though the way
it defeats armor
is very different. This used the power and speed
to penetrate the armor. Whereas this
has an explosive
charge in it, which is what damages it. It used a completely
different method to penetrate the tanks. And we actually found
some of the remnants. We did. We dug this out
of the earth bank
in the back. – So this is our one.
– Yeah. Just crumpled. The force that has
to do that is mental. Well, thank you very much,
Dan, for teaching me – a lot about how tanks work.
– My pleasure. Well, hopefully you enjoyed
that episode. I did. Feel free to subscribe
to the Slow Mo Guys over here, and make sure you check out
other episodes of “Planet Slow Mo”. – What?
– Nothing.

  1. I admit, it is indeed impressive, however, this is such a useless invention. Expensive to make, consumes a lot, it is used for a stupid idea, as that’s what war is in general, i am sure no one smart would argue that, and after all very easy to destroy!! How useless and stupid of an invention. This said, if it was used for a good purpose, i have to admit the engineering behind it is not bad. Useless and very immature invention but good engineering. (still stupid thou)

  2. So many idiots think Gavin was saying “did you hear that” about the tank.. he was talking about the buzzing sound of the shell spinning.. he even says it

  3. Btw just wanted to say awsome video but it was a M4A3E8 aka the Easy 8 not the jumbo(M4A3E2) you got it right thie first time

  4. Feet and Miles… What century are you living on? Please include the standard SI units that the modern world is using, thanks!

  5. Other tanks in WW2 didn’t need levers to steer instead they used a steering wheel such as the German Tiger tank. The Tiger had a steering wheel instead of levers. The steering wheel in tanks was much more reliable and efficient than levers because levers could jam, come loose, and it would make it harder for the driver to maneuver the tank.

  6. You guys really need to collab with How Ridiculous, mostly 'cause both groups are awesome for mostly the same reasons.

  7. How are such huge cartridges made? Can they be reloaded like a smaller cartridge such as a 9mm but with a bigger press?

  8. former tank driver here, They put them self in danger NOT locking the turret and having that handle freely spin…The us safe part is the instructor could get hit with barrel of the tank .

  9. Next step : Firing shells out of a Jg-Pz-E100. Or from a T110E3 if you want stay in the US colors. Or try a Conqueror Gun Carriage

  10. this is a video from world of tanks but it explains very well penetration mechanics and shells caracteristics in real life.https://www.youtube.com/watch?v=UFktFSJZPsQ

  11. Pizza guy: I can't seem to find you, where are you? I think your house is obscured by this ridiculously big tank.

  12. You guys should check out HEAT rounds. I think that is what the 152 shot. It causes an explosion inside the shell that is so hot and pressurized it blows a hole through the side of the tank. Super crazy science for back in the 40s.

  13. That 152mm shell that deflected off the watermelons came down 3 miles away and killed 3 deer, 6 squirrels and 2 campers in a tent that were about to lose their virginity…nice going!

  14. That’s a Jumbo? You wouldn’t think a Jumbo had a Easy 8 Modification to the suspension and tracks now would you?

  15. Один пиздеж. А непосредственно слоу мо выстрелов практически и нет.

  16. This was brilliant. I could see how utterly delighted you were driving that tank, and I really valued the tank knowledge afterwards. Thank you so much.
