If it's worth doing, it's worth doing with X-S.
Inspired by David Chesters suggestion of using a freezer spray or liquid butane to force a sudden ink reveal, I went a bit further and used the same technique in reverse.

    the only time I ever used an erasable pen was as a kid in school. I imagine this would be terrible here in New England, in the winter you'd write your homework in erasable pen, and while walking to school the next morning all your errors would come forth obscuring everything else you wrote.

    Or worse yet all the penises you drew in the margins and erased would reappear on the walk home so your mother would see when you took your books out to study. Or worse than that I suppose the nuns at school seeing. I think I prefer my erased things to stay erased.

    Although temperature sensitive ink pens with thresholds at -80, -20, 5, and 15 would be super useful in labeling temperature critical things in the lab. I could write mean messages to the undergraduate students on sample vials and when they store them inappropriately they'll get my message immediately!

    Excellent. The huge flame followed by "yes,that works" made me laugh.

    Probably a handy way of keeping a record of passwords, assuming no one knows you're using this trick.

    For added stealth, this probably could be done over red text (e.g. address book with addresses written in red) to avoid it being accidentally being thrown out or written over.
