I Lost my Underpants
Ooh... speaking as someone studying psychology and neurology, I'm 99% sure she'd knock herself unconscious before she could proceed- With hard impacts, the brains' natural cushioning mechanism of the cerebral fluids aren't going to be enough to prevent sufficient addling of the cerebrum to let her maintain consciousness.
She'd have better luck using something to cut into her skull- a drill of some sort?
Hmm. How long do you think it would take to drill into the skull?
See, there's a person going to try to stop her attempts...
Depends on the drill. If it's a power tool of some kind... probably not too long. If we're talking a hand-cranked one or something like that, considerably longer- If you want her to pull this off, I'd go for something quick and dirty, because otherwise she'll probably be stopped first- A powerful hand-drill could work. A chisel-shaped attachment, I'm thinking, might have the best results. Again... not an expert, but I'm pretty sure they use a winding implement for surgery so I imagine it's the most effective way to penetrate the thick bones of the skull.
