Probably rice noodles. Have had 'em. Not so bad if they're covered in goop that's not a ramen flavor packet.

…a glass jar labeled “Brain Dust.” It had the kind of packaging that signals discreet luxury: minimalist matte label, custom type, the word “organic.” A 2.2-ounce jar cost $55. “This adaptogenic potion lights up your brain and increases mental flow,” the label said. “Neuron velocity and vision are fine tuned by toning the brain waves, in particular the alpha waves that connect to creativity.” It seemed like the kind of item that might be a prop in a comedy sketch about millennial idiots, or something a person would be duped into buying on a hidden-camera prank show.

It would be a great gag gift if it weren't for the price tag, I guess.

I did not buy the Brain Dust, but I looked it up online, because I will pursue anything that claims to make me smarter. The product’s ingredients were mysterious: lion’s mane, shilajit, astragalus, rhodiola, stevia, maca. It was sold by a company named Moon Juice, which called itself “a healing force, an etheric potion, a cosmic beacon for those seeking out beauty, wellness and longevity.” In other words, a chain of juice stores in Los Angeles.

I'd call it "the latest in 'there's a sucker born every minute' marketing, myself…

PS & FYI: the majority of us in Los Angeles have enough sense to know better than to buy into this crap FFS..

I lost interest when I read that "Brain Dust" contains no actual Brains.

No help here, I've never been crazy enough to find out.
