Some Observations:

[cdave]

• Liquid Nitrogen feels dry to the touch, more than cold. At least at first.
• Material designed to act as a barrier and not allow anything to pass, will not absorb dye.
  Obvious in retrospect.
  I really didn't need faint pink lab coat.
• It takes a special type of madness to recognise excellence in health and safety by presenting pointy metal weapons.
