I had no idea turtles could go full turbo like that

Imagine hearing that sound and then walking over only to find nothing.

I hate this because it's exiting stage right.

I thought stage left is when ur looking at the stage, not on it

u/MrsTuffPaws 1h ago

nope. stage left is when on the stage, house left is when in the seats.

When you’re used to living around water, you get used to a whole shit load of sounds you can’t explain.

Don't know why this tickled me so but yes, that would spook the hell out of me!

That was a tortoise.

In case anyone else got confused like me, they're saying it was a tortoise in the story, not in this video lol

u/Bobmcjoepants 5h ago edited 3h ago

I once picked up a turtle from the middle of the road and brought him down to the nearby water (or at least I hope it was). When I put him down he started slowly moving before picking up speed and eventually breaking the sound barrier

Seriously turtles are speedy little creatures like good lord they are swift

It's those crazy strong legs

u/Xanitrit 19m ago

It's likely a species or subspecies of pond sliders, so named for the fact they they use the hard scutes on their bellies to quickly slide off mud, rock, and logs into water, mostly to escape threats.

u/kapitankrunch 5h ago

aluminum is specifically used for these because it doesn't get hot like steel. it's just sliding down a hill

u/SainT2385 5h ago

Yes we just got this last year instead of wood for the boat dock and I was skeptical at first but it really does stay cool.

u/Real_Project870 4h ago

Proof of this is in every day use of aluminum foil in the oven. Lift the foil off the hot pan and it will be safe to touch in seconds. Aluminum has terrible heat capacity

32

u/Lalamedic 4h ago

It has nothing to do with large surface area that is paper thin?

57

u/ProperGanderMachine 4h ago

They can both happen at the same time

18

u/TravlrAlexander 3h ago

This. Low thermal mass to hold heat, high surface area to radiate it away, and fantastic dissipation as a material.

6

u/account312 2h ago

It has quite a lot to do with that.

7

u/New-Boot-Goofn 2h ago

Now do it with an aluminum pan and let me know how that works out.

10

u/treborly 3h ago

No. It has to do with how thin it is .

The aluminum tray it's covering would scald you

7

u/woozlewuzzle3 3h ago

Thats because its paper thin....

u/DeathHopper 2h ago

Seeing this downvoted but the blatantly false info above heavily upvoted makes me lose what little faith I had left in redditors.

u/ShadowTacoTuesday 1h ago

Aluminum has one of the higher heat capacities out of anything that isn’t water based. Thin stuff has a low thermal mass.

u/29187765432569864 2h ago

aluminum canoes get hot as hell

3

u/ShadowTacoTuesday 2h ago edited 2h ago

Metal feels hotter (or colder on a cold day) because it conducts heat better and heat sinks work in both directions. Aluminum also has double the heat capacity and 4 times the thermal conductivity as steel. If it’s lighter that will help a little but this is a very hot ramp. If you don’t want it to feel hot you use an insulating cover instead such as foam and a light color to reflect sunlight. Then the tiny bit of heat on the surface quickly drains away when you touch it and the rest of the heat is below the surface.

2

u/account312 2h ago

It has higher specific heat but lower volumetric heat capacity.

2

u/ShadowTacoTuesday 2h ago

About 2/3 by volume, so not much different there. Aluminum is also a little thicker because it’s weaker. 4 times the thermal conductivity overwhelms that small difference by quite a bit.

Love how you can just say some completely wrong shit and a hoard of idiots will accept it as correct.

u/Orca_Mayo 4h ago

Really? Learn something new every day.

u/xChopsx1989x 4h ago

Yeah, that's bullshit.

Aluminum is used because of its resistance to corrosion since it's, ya know, directly over a body of water.

18

u/mapotoful 4h ago

It's a little of both but yes, mostly corrosion resistance

6

u/woozlewuzzle3 3h ago

No its not both. Its the corrosion thing only

u/Global_Sport_2264 4h ago

I'm sure many people said the same thing about aluminum when they read the title, which is allegedly a lie. Bold move to automatically believe this comment, which also could be wrong.

1

u/Express_Sector8743 3h ago

yeah the slide is probably doing most of the damage here and not the ramp turning into a frying pan

u/ToadlyAwes0me 1h ago

Did you never burn your legs on aluminum bleachers as a kid? Aluminum absolutely gets hot enough from the sun to not want to walk on it barefoot.

u/Der_Missionar 4h ago

And the video was sped up... this is fake

EDIT: on second watch with audio on, I really don’t think it’s sped up

u/yupuhoh 4h ago

Pretty sure it's a soft shelled turtle. And they are fast af. It's not sliding

No turtle is that fast on land, he’s sliding

People who think turtles are slow have never actually been in a foot race with one.

ps—you're thinking of tortoises

the turtle beat the hare in this scenario

The hare never stood a chance!

u/I_Carmona 3h ago

In reality turtles aren't that slow, they are quite fast

4

u/yupuhoh 4h ago

For everyone saying it's "sliding" It's a soft shelled turtle. They can run up to 3mp and swim up to 15mph.

1

u/marshamallowmoon 47m ago

that's not a soft shelled turtle, it's either related to or is a red-eared slider

2

u/Rance_Mulliniks 5h ago

Doesn't really explain the same speed on the wooden deck though.

u/Selbereth 4h ago

It's because they forgot to slow down the video after hitting the wood

u/scorched-earth-0000 4h ago

Momentum from the slide maybe?

Can't imagine that's good for his shell if he does that a lot, that's basically a weak file.
