Almost everyone who sits for exams know the dreaded feeling when you have no idea how to answer the questions and end up submitting a blank piece of paper which will consequently cost you your grades.
But for one Japanese student, submitting a blank essay paper resulted with her getting the highest score.
How can this be possible, you may ask?
The student, Eimi Haga, who enrolled in a ninja history class pulled the stunt that impressed her professor when he realised she was using invisible ink, reports BBC
The words written on the paper were only visible once it was heated on a gas stove.
The stealth ninja technique known as ‘aburidashi’ takes hours to create as it uses an ink made of soy beans which has to be soaked and crushed first.
“It is something I learned through a book when I was little,” Haga told BBC
The 19-year-old has taken an interest in ninjas ever since she watched an animated TV show about it as a child.
The Mie University student was tasked to write an essay about a visit to the Ninja Museum of Igaryu.
Her professor says that those who did the assignment with creativity will be awarded high marks.
That’s when she decided to send in a ‘blank piece of paper’ which garnered her top marks.
"I gave a thought for a while, and hit upon the idea of aburidashi
The professor, Yuji Yamada, told BBC
he was "surprised" when he saw the essay.
"I had seen such reports written in code, but never seen one done in aburidashi," he said.
We’re pretty sure a lot of you are impressed with Haga’s efforts and perhaps the next time you submit a blank paper to your lecturer you should tell him or her that it’s written in invisible ink.
