Anyone who's seen this can attest to just how cool it is.

What they do is take a mixture of cornstarch and water, than vibrate it at certain frequencies. That is, not just moving back and forth quickly but in a specific wave pattern. The gelatinous substance takes on the properties you see here.

How cool

It doesn't inspire much confidence when they misspell "cornstarch" in the title card of their video.

Cool. Does it have to be cornstarch or can I make my mashed potatoes do that during Thankgiving dinner?

i think making a flamethrower out of your own house parts is way cooler, but also way more dangerous and risky.

Right. They've lost all credibility due to the lack of a spell-checker.

And you should also discredit psychologists because of their awful handwriting.
And you shouldn't trust mechanics because of their bad hygiene.
And you should be skeptical about surgeons because they work 32-hour days.
And I'm not that good of an artist/musician because I bite my toenails.

Coolness. The fingers thing looks pretty goddamn creepy.

Yeah, cornstarch is weird. That was the first thing we worked with in Materials Science.

That was pretty awesome... even somewhat gross. I like it.

I went to the lab and tried that shit today and i got it. I found the freq. at a website.

I think it has the freq. in the video.. no?

yea it did

wierd, just wierd.

yea but it didn't really work, they must have done something else.
