Best Test

My 16oz can of Best-Test Paper Cement used to reside on the window ledge above my radiator. However, I recently noticed that when my heat went on, the can would expand - making very funky 'thick-metal-crinkling' noises. When the heat when off, the vapor inside the can would cool, and there would be similar (yet opposite) 'thick-metal-crinkling' noises. This morning, I actually read the side of the can:

When using extinguish all flames and pilot lights, turn off stoves, electric motors and heaters. Avoid sparks, static discharge and other sources of ignition. Avoid skin contact.

Excellent! Did I mention that I have practically no ventilation in my apartment and have been using this stuff for years?! It's a wonder I haven't blown myself up yet. And how many times have I rubbed paper cement all over my hands in order to create a hand full of boogers to the joy and amazement of my friends?! The 16oz can of Best-Test Paper Cement no longer resides above my radiator. It is currently stationed on my desk, next to my monitor, where I can keep a constant (and suspicious) eye on it.
