You have to see these videos and just laugh, laugh loud. Has anyone ever thought of doing this in a 100% oxygen enriched chamber while in it? I hope not!
For those that cannot access the videos; these videos are of two males in a collapsible plastic chamber with 30% oxygen in the atmosphere at 1.3 or 1.4 ATA lighting various items on fire while inside of the chamber. It was hard to beleive at first (still is actually) but it looks pretty real to me.
