I wouldn't really want you to stick your hands in something running either. More so something created by the Malnosso. To be perfectly honest, not sure how safe I'd feel if I had to stick my hands in anything of theirs even if it was off.

[Vash sighs.] Why is there never a trustworthy manual that just clearly states: This is a BAD idea to turn this off. Or even better: It's perfectly safe to turn this off! That would be nice.
