Thanks. I knew about taking the highlighter out and swirling it in water, then i saw this video. I never would have thought it would be that easy.

Many fun things can be extracted in this manner

Try Isopropanol (IPA) as well, it will evaporate off at room temperature (although please use in a well ventilated area etc etc etc)

It's also pretty hand safe BUT extremely flammable.

This. Isopropyl is basically that alcoholic handwash that you get in those hygienic gel things - even at the, what, 40% concentration that it's in there it still works for extracting fluorescin (and permanent pen from your shirt!). You just need to leave it a bit longer to evaporate.

isopropanol = ispropyl alcohol :na:
