Natural sample, 78% Pure. I collected this sample of naturally occurring air (78% pure nitrogen) from about 20 feet away from the table in May, 2002. The sound for this sample is a beautiful 78% nitrogen, 21% oxygen wind sound borrowed from ftp://ftp.zib.de/ pub/ UserHome/ Luegger/ Urania/Sound/ FX-03.WAV . I've got a story and video of making ice cream by pouring liquid nitrogen directly into a mixture of cream and chocolate syrup.
