Gotta love d3o, every designer's material du moment. Not only does it come in funky skiing hats ( I soooooooooooooooo want one), but here's a little demonstration of just how violent you can get with it:
That's what it does. Most of the time it's flexible and malleable, and doesn't restrict movement; but if you hit it it hardens momentarily, absorbing the shock and as Peter says, spreading it over a wider area. Mostly it's being used right now in sports protection gear.
A few applications, from the website: Soccer goalkeeping glove "The Contour d3o goalkeeper glove and d3o Pro Pad hit the shelves in Spring 2006 and are sure to be used by some of the world’s tops players in the World Cup in Germany, including Poland’s Jerzy Dudek & England’s Robert Green.
The Contour d3o glove boasts a soft and flexible d3o foam punching zone, which stiffens when the goalkeeper punches the ball, providing total protection and a solid platform for the punch. The reaction is instantaneous, lasting 10 milliseconds. In that time, the molecules lock together to absorb the impact energy. When the impact is over, the material returns to its flexible state."
skateboarding shoe "Globe launched the Icon shoe containing in the US this October (2005). The shoe has been eagerly awaited by skateboarders and retailers alike and is the beginning of a new standard in skateboarding footwear. d3o is used in the heel of the Icon to absorb the considerable shock that is transmitted when skaters miss-land a jump and impact the concrete with great force which causes heel bruising."
Yes. The property is called dilatant, and basically means, insoluble particles suspended in a liquid or gel so that any impact has to move all of the particles out of the way one at a time in order for the wave to ripple. (someone please correct me if that isn't right, I'm no physics major). If you want to play around with a dilatant substance [savymasters] mix corn starch with water in a coffee cup or similar container until full and it becomes hard to stir. Now try to stab a knife to the bottom of the cup with all your might.
Does anyone know what happened to that custard running video that was posted recently? It seems to have gone POOF. Talk about your suggested experiments. Water Walking 101.

That's interesting. I imagine it would be very useful for clothing for people in high impact situations - construction workers, police, kick boxers.
What? It can protect people wearing them from such violent impacts?
It spreads the impact out over a wide area. So it's like wearing body armor that's only hard when it's hit.

So, stuff like that. Lots of skiing gear, too.
I want to see the video demo of the custard filled jogging bra that someone once suggested...
Thanks.
So it has huge business potential as well as the service it can provide to people pursuing the aforementioned occupation/hobbies.

I did an answer.com search and found out more about it. The suggested experiment will be done with a couple of my students.
[BAM!] [thud] "Ah, that didn't work...Next!"

It's in the bakers/2 group here.
I tried the link, but got an error message.
Hmmm, works for me. Thanks worldgineer. Maybe it was down for a bit.
Here Murali - try this one.
Tried. Thanks.
