As I said in my Patreon preview of this page, they were talking about hands :D

It would be awkward if Edgar said a human name to describe the science of his “sticky” hands.  Hm… I can’t make up my mind if Inter molecular or Temporary molecular sounds better. I just went with the one that sounded easier to understand.

That’s enough science Morbidprince, get back to Yaoi :P

Well at least the page is done! :D
