Genie in the bottle

They say you can’t put the genie back in the bottle.
But you can kill it and chop it up and put the pieces in a blender and pour it back in.
Yes, genies are bigger than the bottle, but they managed to fit in there before, and they will again when you pour them back in.
There are perfectly rational explanations through physics.
Genies might be low-density creatures, who compact easily.
Or the inside of the bottle may have neutrino star material with a highly-localized gravity field to compress the contents.
Or, yeah, it could just be fucking magic.
