Item Specification: Insulated Thermos Flask

Insulated Thermos Flask

"For some reason, if a strag discovers that a hitchhiker has his towel with him, he will automatically assume that he is also in possession of a toothbrush, face flannel, soap, tin of biscuits, flask, compass..."

— The Hitchhiker's Guide to the Galaxy, Chapter 3

The Insulated Thermos Flask is a double-walled, vacuum-sealed thermal vessel manufactured from brushed spun aluminum with an internal borosilicate reflective lining. Designed to defy the second law of thermodynamics over moderate interstellar commutes, it keeps boiling liquids piping hot even when floating through the icy cosmic chill of the Horsehead Nebula.

Deep Space Refreshment

Hitchhikers prize the flask above nearly all other field messware:

  • The Screw-On Cup: The threaded outer cap unscrews to form an insulated handheld cup, allowing travelers to sip hot beverages without scalding their fingers while sitting on an asteroid waiting for a ride.
  • Liquid Payloads: Common contents include hot chicory brew, boiling water for rehydrating emergency yeast pods, pure Santraginean Seawater, or a medicinal splash of Ol' Janx Spirit.
  • Companion to Biscuits: Naturally paired with a Sealed Tin of Biscuits. Any hitchhiker observed unscrewing a thermos and producing a crunchy biscuit from their satchel instantly commands the awe and respect of all nearby strags.
