Way too cool.

how the hell?

idea: anyone with a girlfriend who bakes, and you are thinking of popping the question to? bend it into "will you marry me" and then when cool unbend it around the baking sheet. pre-heat the oven, message appears!

disclaimer: I'm not sure if it needs heat alone, or if it has to be hot liquid/water... also, this stuff may be toxic, you don't want to give her heavy-metal poisoning.

Whaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaat?

I've seen spoons made of this stuff. They bend at a right angle when used to stir coffee etc. Best eva use of NiTi IMO

I saw a show on Discovery or something where they used this tech to insert stints into arteries. They'd normally be coil tubes, but they'd freeze them and bend them straight, then insert them through a tiny slit in the wall of the artery, and when the blood hit them and they'd warm up, and become a small coil again, opening up the artery clogged by cholesterol.

They also showed the opposite tech, where it has a shape when it's cold, but when you heat it, it forgets.

This was ages ago. Maybe more than ten years.

After a hot bath I feel brand new too!

Companies that make products for Erectile Dysfunction need to see this NOW!

^Ow, ow, that hurts just to think about.

That's so TOH.

Whoa!

Witchcraft!

A duck!

Who are you who are so wise in the ways of science?

I want my 45 seconds back. Here's what you kids vote into the top whatever now. Gone is the Videoshift of old. Sigh.

It is a memory shape alloy. Another thing we crazy scientist study...

To my knowledge it's not toxic and only requires heat to reform regardless of it's form. I had a kit once that used a band of Nitinol wound like a spring. You would wind it around this wheel system such that one end could be submerged in cold water and the other could be submerged in hot. The thing would take off like a shot and spray water everywhere. Still, pretty neat.

Expecting a KISS video on the top 15... Glad it wasn't

I got something that can remember its shape too.

This is just a brand name of a nickel-titanium alloy. This stuff has been around for ages. My orthodontist mentioned it at least 10 years ago.
