"Just be careful where you place the papercraft, because it surely contains printed microcircuitry with hypersensitive cellulosic fiber antenna that will transmit whatever it is you say..."
There's something dodgy about their claims IMHO. Either their test methodology was faulty (for instance, perhaps they didn't properly account for the roughly 35% change in atmospheric pressure from the altitude where they took the samples to where the readings were made) or they knew that measuring a gas at different pressures would produce these results and are just looking for some suckers to help fund their hobby.
Cool so it plugs into Twitter?
