Why not to distill anything in a closed apparatus.

In this case I was distilling some abs. dichloromethane from phosphorous pentoxide to remove traces of ethanol what was used as a stabilizer in the solvent. When I closed the system as seen on the above gifs, the internal pressure risen and the excess pressure left the flask by removing one of the glass stoppers.

So: NEVER DISTILL ANYTHING IN A CLOSED SYSTEM.
