A little cool thing called shape memory. It’s made from an alloy of titanium and nickel (I believe it’s called nitinol). It has the ability to “remember” the shape it’s taken. When cold, you can bend it whatever which way, but once you heat it (or in this case put it in what I presume is hot water), it will take the original shape.

Funnyjunk users are so kind to one another. They're friendly and patient and will explain anything as many times as necessary without complaining. What a great website.

After one minute, I quit watching. Very nice and time consuming timer.

****		 it heres a game of snake to go with that timer (So you can time the game.)

I just spent over 6 minutes watching this gif... it was beautiful

Please tell me how long that ******* timer goes on for, or I can't change the page.

I didn't know myself, so I put it in my gif editing program to look at the last frame...and the gif killed it.

It just restarted though so I'm pretty sure it's 5 min.

It restarts at 5:01:00

Did you just... Stare at it for 5 minutes and a second?

Nah, I've had other people do it for me. I've had it as my avatar for more than half a year, and plenty of people respond to me telling me that's when it resets.

Ah. I just saw your avatar. Hooookay then.

i cant science good, what is this?

I think it`s a NITI wire, you can manipulate it with cold water and regains its original with hot water or saliva, because the NITI wires are used in orthodontics treatments

Yeah mr Wolfdogone, yeah science!

Imagine the outside of your car is made with this, or something similar. Got a door ding? Splash some warm water on it. You might still be missing paint though, but whatever.

The timer is useful for 2 reasons :
>To show that the sequence is not reversed
>To show that the sequence was not speeded up

This is nitinol, a metal that reforms the shape it was cast in when it is heated.

Looks like they replicated the car repair system from Carmageddon.

Hell yeah, you looking forward to Reincarnation?

I thought that project died a long time ago?
User avatar #71 to #70 - certifiedidiot ONLINE (05/23/2013) [-]
Nope, it got funded on Kickstarter, goal was 400k and it earned in around 650k, I backed it with a thousand myself.

That's the kickstarter

That's a pre-pre-pre alpha sneak peak

thanks for posting this it reminded me of something I wanted to link to on here.I will give credit to you for reminding me

shape memory alloy: at the high energy state (hot) the metal has a cubic crystal structure. when cooled below a critical temperature, This cubic state is no longer stable so the crystal structure becomes essentially a 3D rhombus. These different "rhombi?" (forgive me i'm doing this from memory) form by nucleation as random individual nanocrystals will deform and then larger crystals will precipitate around the first crystals nucleus forming large areas of metal with the same orientation. Where areas of different orientations meet, they form morphological boundaries calling twins (the formation of this is often called twinning). when the cool metal is deformed, the deformation occurs around the twin boundaries without stress. When the material is warmed back hot enough that the cubic state is stable, the boundaries become unstable and disappear. The mechanism of their removal pulls most atoms back to the original location and so the original shape reforms.
