A student of ninja history in Japan took her education to stealth mode when she made a seemingly blank paper for her dissertation.
Eimi Haga wrote the essay with invisible ink.
Haga told the BBC that she has been interested in ninjas since she was a child. So when it came time to start her freshman year at Mie University, she signed up for a ninja history class.
The professor asked the students to write about a recent visit to a ninja museum, saying he would give high marks for creativity.
“I decided to make my essay stand out from the rest,” Haga said,
Haga therefore used the “aburidashi” technique, which involves soaking the soybeans overnight, crushing them and pressing them into a cloth. The extract is then mixed with water to create an ink that fades as it dries.
She handed the top-secret prose to her teacher with a note that said “heat the paper.”
This is exactly what he did. And to her surprise, Haga’s words became clear as the day he held the paper over his stove, leaving her with no choice but to give it top marks.
Haga admitted that the content of the essay itself was “nothing special,” but she was proud of her smart work.
“I was sure the professor would at least recognize my efforts to give it a creative try,” she said.
