I am trying to fix one of those half water, half blue-colored oil keychain after they evaporated/dried out over the years. Google only suggests using oil-based food coloring, but it seems like here where I live, they only seem to sell the usual water based coloring.Do you know anything else that would have the same effect? Any powders, paints, maybe candle dyes, or if you know anything else (even if marketed as another product)? It doesn't need to be edible/safe to eat either.Is there anything else you can think of? via /r/DIY https://ift.tt/2PU1Otv
