“Student Uses Invisible Ink to Ace Ninja Report”

A Japanese student aced an assignment on ninja culture by making her own invisible ink from soybeans in a stealthy move that impressed her professor.

Eimi Haga, a member of Mie University’s ninja club, turned in an essay on a visit to a museum about the nimble assassins with an attached message to heat it before reading.

“I knew that I needed to take it home and put it above a stove,” said Yuji Yamada, who teaches Japanese history, including ninja culture.

“She replicated what is written in records of ninja art. She strived to prove what was written actually works and went through a trial-and-error process. I was impressed,” he said.

When the characters of Haga’s essay revealed themselves in the heat, Yamada—who had promised his students extra marks for creativity—decided to award her an A.
