can anyone figure out if this is a hoax or not?

Well, it is a joke website, but this concept has been kicking around in science fiction (which, of course, mirrors science) for a while.

I just noticed a URL at the end of the video to ScienCentral.com. Seems legit.

Cor blimey, this was bouncing around already in the ancient sci-fi RPG AD2300 almost two decades back... Now for the orbital elevators. :2thumbsup:

Well, a impact hardening fluid matrix isn't anything new.

Has anybody ever done that experiment in elementary school with the corn starch and the water? Yea, it's like that, except it works faster.

I saw a clip of this on some show on the military channel just the other day, seems legit and very cool. :2thumbsup:

We use to call the cornstarch and water stuff ooblick, neat stuff that is like a liquid but if you hit it with a hammer it will crack then in seconds it all flows back together like a liquid.

Saw it mentioned in passing on the history channel. I think it was an episode of modern marvels on body armor. Sounded like it was nowhere near completion but was being worked on by military scientists.

i have to know what this "cornstarch" thing is - does anyone have instructions or a link or something so i can reproduce this experiment myself?

If I remember correctly it is a 2 parts water to 3 parts cornstarch ratio, but you can just play with the consistency and even add food color for effect.

There are videos of this stuff out there all over too. This one is weird (https://www.youtube.com/watch?v=nq3ZjY0Uf-g).

I wonder whether it´s similar to the gel used in protective motorcycling clothes that will become very hard when you fall and slide on the road?:inquisitive:

Yeah, its real. Its known as shear thickening liquid.

I put it this way it is a thing that is made in kindergartens / pre-schools by the teachers or the kids themselves so I think you can safely make it.

I liked adding red food dye myself it makes a wonderful pink goo. Difficult to wash off the hands, but you can eat it.

The particles act like traffic... too much and it jams, a little less and it flows.
