So I'm getting paranoid right now. I normally write in black pen and I wrote a note on my hand at school. At the end of the day the ink was blue but I thought I maybe wrote in blue pen that day. But then the next day, the same thing happened again!
So I told my friends and we tested writing in different black pens on our hands and after..3-4 hours, the black ink turned blue on my hand but there was no change on my friends' hands!
Why is it that the black ink turns blue when I write on my hand guys!!

Cus blaxk ink is usually made out of several colours.
Can separate all the ink pigments out in something called Chromatography.
Year 8 science basically.

Due to chomatography.
