You Die
you die
pain
you die...
Nothing happens
You can get chemical burns along your throat and stomach if you swallow lye.
You burp bubbles
It depends on how much you swallow. If it is a large amount, you could get diarrhea and/or vomit.
You'll choke and die
Your ink drys out.

This too will pass.
