Today, we tie dye! The normal way of tie dying can get a little messy, so we opt-ed for the more controlled tie dye. Plus, then we could add in a little bit of science! As we all know, sharpie ink does not come out (well) with water. This is because the permanent marker is not soluble in water. It is, however, soluble in rubbing alcohol.
