Bonesaw- Absolutely Absurd

The drill penetrated the bone, reaching a small hollow compartment.  She pulled the drill out, caught a cloth in her pocket between her pinky and ring fingers, and wiped down the bit and the end of the drill, before pulling it out and turning it around.

The end of the drill had deep scratches in it, easily mistaken for the teeth of the drill itself, holding the bit firm.  Instead, it was a key.

She slid the key into the hollow compartment, scraped it against bone until she found the socket, and turned it.

A single droplet of coded chemicals was released into the ‘marrow’ of her bone.  The marrow immediately liquefied, and the entire bone with the various things she’d screwed into it, the segments she’d capped off and connected to one another, and the patch jobs, all came to the point of almost collapsing on itself.  Her entire leg squelched loudly.
...

She pulled out the tube and drew a canister out of her pocket.  She began loading in a fresh solution of the same dual-state biomatter.
...

The fresh fluid was loaded.  She capped it, inserted a droplet of catalyst, and screwed in the key.  It was her kit for a worst-case-scenario.  In a scenario where she was imprisoned and needed out, or if she found herself in another situation like she had when the portals had ripped wide and tall, she could access her thigh bone, empty the contents, and they would congeal or grow into a setup sufficient to get started up again.

A liquid workshop.
