Fishing Wire for on Camera Hair Effect?

Hey All,

I am directing a short comedy, Cowlick (https://www.facebook.com/cowlickfilm), and I need my lead character's hair to stick up like alfalfa from "The Little Rascals."

The cowlick will pop up while on camera (meaning we need it to go from shellacked to his head to pointing up sky-high). We are thinking that attaching some type of fishing wire or thread to a well gelled "cowlick" might do the trick, but wanted to see if anyone had better suggestions.

We have a test shoot coming up and will be able to try just about anything. My lead's hair is jet black.

Thanks so much!
