Science Buddies: "Ask an Expert"

What is an easy way to test for methanol? This is actually for an economics project but I'm marketing all natural bath bombs but am having a hard time dissolving all the pigment in just water. I am trying to dissolve it in methanol/water mixture but I need to test the methanol levels after the pigment is dissolved.

I am doing a project making bathbombs and I was wondering if anyone had suggestions on dissolving pigments besides alcohol? like maybe propylene glycol or polysorbate 60? Thank you!
