As he is using dry ice which directly changes from solid to gas (knows as deposition), this would prevent the package from getting damaged but I wonder what how the gas would escape?

Ok, I'm sorry but I just have to jump in here and fix this MASSIVE inaccuracy.


You aren't deposing the dry ice, in fact you aren't doing anything to it. The dry ice is subliming.

Spoiler:

I do apologize for this being mildly off topic, but you can't have quality without accuracy
