Does marshmallow fluff explode on airplanes?

I just took two containers of Fluff from Sturbridge, MA on two flights on Feb 3, 2013 - one at 24000 cruising altitude, one at 35000. The Fluff came through just fine. Not knowing whether it would, I did Duct Tape the tops (one screw on plastic jar, the other the snap-on) and put each in a freezer baggie. This might be a reasonable precaution! The Fluff also survived sub-freezing temperature in the baggage car of Via Rail from Thompson to Churchill, Manitoba. So, I would say Yes, Take Fluff To Your Friends!
