After 3 long days of planning, hacking and pure frustration:

Me: 1, Rubber stopper: 0

I ended up finding this exacto knife (more like those surgical knives you'd use in biology, but with switchable blades) that had the blade i was looking for, one that was sharp at the bottom, like so (excuse my poor ASCII art :)),

The bottom portion was sharpened, so it was a matter of sticking the knife with the blade down onto the rubber stopper....mind you the handle was a tad too short, so I ended up sticking my fingers into the flask as well. After about 2 hours of just repeatedly hacking away at the stopper, it broke into two pieces, and I managed to pull it out :D

What a satisfying end to a nightmare

Edit: My poor "diagram"

No, you're heating the flask inverted, so gravity, as well as the increasing pressure in the flask, holds the stopper in place, like so (your ascii art inspired me):

Code:

[Edit: that's still not right. The preview works, but the main display shows the double backslashes literally, and doesn't work with single ones.
