You can also use highlighter ink as an alternative to the paint. Just pry off the bottom of the highlighter and drop the ink filament into the bowl of hot water and borax. With a gloved hand, squeeze the filament to extract the ink. [2] X Research source Note that if using highlighter ink, it may only glow under a blacklight.

As an alternative to glow-in-the-dark paint, you can instead use the ink from a highlighter to color your slime.
