I feel sure that Misty can advise you on Graham's Law of Diffusion.

I feel more sure that you can advise him far better than I ever could on that subject.

Hardly Misty.

I here your specialism is effusion.

Fan  tastic  story. That is what it is fantastic. A little girl as smart as Madeleine doesn't know who she is?  like seriously hahahahaahaha.

You think a child taken from her parents before her fourth birthday would certainly know her true identity 10 years later?

If you believe that myth then never light a match downwind of me.

Don't worry, that won't be a problem.

Try looking under gas permeability coefficients for polyethylene as a start point.

Do you think they have tested polyethylene for permeability for the two gases putrescine and cadaverine I doubt it very much.

OK then you can find a cite where it says it hasn't been tested, to back your assertion.
Then while your at it find a cite that says a gas of the same molecular density has not been tested. You only have to find one as fat or skinny as the case may be and you have the answer.
You seem to have an objection to working from first principles at anytime. I wonder why that should be so?

would that make your speciality confusion

Not near a cite.

Not near a cite.

it seems polythenes are gas permeable and vapours permeate to a greater degree...lots of factors affect the permeability....humidity being important

Thank you for this.  Let me see if I can summarise correctly.

In 1969 time, if you blew up a plastic bag to over 8 times normal pressure, it would leak through the 'skin'.

I am not trying to shoot the messenger.  I am not even trying to shoot the message.  I am just asking a simple question.

Do 1969 plastic bags blown up to 8atm relate to the curious case of Madeleine McCann?  Cos I am curious.
