Reply	Anonymous says: You#39;ve had them for 2 months at room temperature? Umm.. im no expert but i think it might be time to throw them out. As for shrinkage, see if there are any bite marks. Just a thought.  (no votes) Tags: technology, domestic science, human body.

Reply	doctor007 says: I cannot expline the shrinking of the actual crumpets but bucause plastic is not a uniform matirial there are small holes out of which the air has escaped. I shall assume that these crumpets were at the bottom of the freezer where cool heavy gases congregate, for example nitrogen and the dreded carbon dioxide.  (no votes) Tags: technology, unanswered, humanbody, domesticscience.

Reply	transistor says: Two things to note: NITROGEN The products are flow-wrapped. See http://www.youtube.com/watch?v=ivQ2_cFxXzw&feature=related for an example. At the point where the packing film is formed into a tube it is common to inject nitrogen into the pack to displace the air. This will greatly reduce any mould growth. FILM PROPERTIES Plastic films are not gas-proof. Gas, including air, will slowly migrate through the film at a rate dependent on the material and the thickness. Try chopping up an onion and popping them into a sandwich bag without getting any on the outside. Seal the bag and check for odour after a day or two. I'm not sure how this would explain the shrinkage though.  (no votes) Tags: technology, unanswered, humanbody, domesticscience.
