Invisible Ink Brings an A in Ninja History Class

A Japanese student handed her professor what appeared to be a blank sheet of paper for her final exam in a ninja history course at Mie University in Japan, the BBC reported.

Haga was asked to write about a visit to the Ninja Museum of Igaryu and when her professor told the class he would give high marks for creativity she settled on the novel technique. "We discussed the use of invisible ink but I was amazed that someone actually used it", he said, adding that he didn't read the entire paper because he wanted to keep some of Haga's work invisible.

"The professor told us that our creativity, the better it would generate", says the eerstejaarsstudente of the BBC.

'I gave a thought for a while, and hit upon the idea of aburidashi'.

While giving a teacher a blank piece of paper and letting them figure it out could have been a cool idea, Haga decided not to take chances and included with her work a note explaining that the essay should be heated first.

She then mixed the soybean extract with water, spending two hours to get the concentration just right to create the ink. Once dry, her words could no longer be seen.

According to The Guardian, Eimi Haga, a member of Mie University's ninja club, submitted an essay about the assassins with a message attached instructing the professor to heat it before reading. "She replicated what is written in records of ninja art".

"I had seen such reports written in code, but never seen one done in aburidashi", he said. He conceded that although he had some doubts that the words would come out clearly, he was pleasantly surprised by the results.

Haga admitted that her essay's contents were "nothing special" but she was confident her professor would mark her highly due to the effort she had made.

"I didn't hesitate to give the report full marks - even though I didn't read it to the very end because I thought I should leave some part of the paper unheated, in case the media would somehow find this and take a picture", he said.
