LOVE IT!!!--We had plugged deck drain on the carrier is was on back in the early 80's--so early one morning around 0dark30 we finally decided to try a 15# CO2 fire extinguisher to blow it out--seemed to work--built pressure then released--ran some water down it and it went down--next day we heard it mentioned that they were looking for the guys who blew out a drain and smothered the Chaplain with all that gunk--wonder what the Chaplain was doing up at 0330 or so and shaving to boot--I Imagine that stuff blew out his sink drain kinda like the stick in the OP--
