Another dry ice disposal story worth sharing is that disposing of a large amount of it in the sink is a bad idea.  The sink and the drain pipe have different expansion (in this case contraction) coefficients, and the fact that the washer becomes brittle like hard plastic can break the drain seal resulting in a call to the plumber to fix a leaking sink. 

Just thought I’d pass that one along.

There’s an interesting story about disposal of dry ice at home and lessons learned at

It could provide an interesting opportunity to do a hazard analysis in a lab safety training session.
