Literally any glow in the dark material and a 405nm laser or a 445nm laser

but what liquid can do that so i can paint it on a wall or something but thanks for the quick reply

There's glow in the dark paint, dunno if the liquid stayed glowing but highlighters will make the liquids glow so long as the laser is pointed in it. Anything a blacklight will make glow the 405nm will and the 445 probably will
