[CHEMICAL] DNA in puke/urine piles; GLOWING REVERSIUM

[APARTHEID]

Just as the topic suggests. Let puke and urine pools contain fractured traces of a crew member's blood DNA print for future analysis of who's being a drunk and who is just downright rude.

GLOWING REVERSIUM, on the other hand, would be an empowered version of reversium that reverses your screams and farts. That's about it.
