Can i make my ink thicker?

Question

ok so im gonna go bombing this weekend and it just so happens that i ran out of refill ink ( i buy the 200ml refill bottles cuz im lazy =]) I dont ususally make ink but when i do i just use alchohol and some sharpies or pens or w/e i have and i was wondering if theres anything i can throw in to make it thicker, cuz i hate when its all runny and sh*t

Answer 1

you could open one of your arteries and collect it in your ink bottle?  I think the blood may help your ink coagulate a little...
