1. FLAP
Raewyn wore socks and had the smell extracted by and analysed by Robert Winz at Plant and Food Research laboratory, using HS-SPME-GC-MS, which means 'headspace (HS)/solid phase microextraction (SPME)/gas chromatography-mass spectrometry (GC-MS)' , a method which was developed to determine the profiles of volatile substances.
The chromatograms that Robert produced were not what were to be expected based on the literature - according to the machines my feet smelt like sweet lovely fruit! also, although the socks were boiled several times and hung out to dry on the line, the background ‘clean sock’ compounds hadn't been reduced to a minimum.
We decided to press on with collecting our own plus kind friends' and willing volunteer's foot smells.
