Parafilm is like thin sheets of wax. Imagine the stuff they put on cheese cut up into sheets. We use them in the lab to wrap and seal tubes for centrifuging and stuff.
As for the breather bags...Again...I'm not 100% certain if the rxn will happen fast enough. Making a CO2 probe that only reacts 3 hours after any changes occurs isn't really a good detector...I have no experience with making a probe so I can't say how permeable breather bags are but I don't think they're more permeable than the interaction between air and water. Meaning you will never get faster than a drop checker's speed without making the fluid layer extremely thin. And so considering that a drop checker can take upwards an hour to react you're looking at a very slow rate.
