As your lawyer, I would advise against it. Per
Chapter 3 subsection a it states "Devices may be constructed of and contain anything except the following materials/components: asbestos; mineral wool; fiberglass insulation; commercially available thermoses/coolers/
vacuum sealed devices." Yet also as your lawyer I suggest you
can make a case that it is not a
vacuum sealed device (Such as a yeti) but it is a vacuum sealed insulator. To be safe I would submit an FAQ to soinc and ask what qualifies as a vacuum sealed device.

Thanks for the answer.
Has anyone else noticed that plastic beakers are much bigger than glass ones, even though they are marked for 250 mL?

May just be where they each came from. Manufacturers seem to vary in the amount of extra room left in glassware.

Does anyone know if it would be advantageous to use oxygen absorbers that come with mylar bags, and if this would even be allowed? Thanks!

The bags or the absorbers? Why would that be advantageous?

Are gallon sized ziplock baggies included in the "commerial" vacuums, or are they allowed?

Last I checked, Ziplock baggies aren't very good insulators nor are they vacuum coolers, so it should be fine for you.

Thermo is a great event for all who like studding heat and cold.

I'd just like to point out that it doesn't just involve hot and cold but also the nature of energy, gas theory, etc.
But thermodynamics is pretty cool.
