Whichever one you want is yours. I don't really mind either way. Its just me trying to being strange and trying to figure out minor details. On a more important not though-the plot. The most obvious thing to figure out would be exactly what kind of experiment it was/is and what/who its for. Something like gene-splicing/dna mixing for....some reason that I have yet to think of? Bioengineering for health purposes/to create super whatevers? Cyborgs/Frankenstein/test tube things to test the laws of science?
