Product review & video
(upbeat music) - The legend around this
chalk is that it's impossible to write a false theorem. - I assume the special
ingredient was angel tears. - Mathematicians from all
of the top schools very frequently use it. - It's a cult favorite. - As soon as I use it I was a convert. - The chalk is one of
the best kept secrets in the math world. - It's the Rolls Royce of chalk. (gentle music) (chalk scratching) - Hagoromo is a brand of Japanese chalk. The way it flows on a board
is a bit hard to describe in words. - It's really hard to get. You can only get it from
Japan, you need a Japanese person to bring it back for you. - I discovered it when I went to visit the University of Tokyo and
one of the professors there said to me, you know, we have better chalk than you do in the States
and I said, oh go on, chalk is chalk. And so I tried it out, and
I was surprised to find that he was right. -
