This Armbrust Cup was among the survival gear Charles Lindbergh and his wife, Anne Morrow Lindbergh, brought with them on their 1931 flight to the Orient and 1933 survey flights across the North and South Atlantic. By condensing moisture from breath into drinking water, the Armbrust Cup (named after its inventor) would provide a few last sips of water when there was nothing else to drink. It did not, however, provide a permanent solution to dehydration because it only recycled lost moisture, and did not provide a new source of water.In case of an emergency landing, Charles Lindbergh always took an Armbrust Cup with him on flights over the ocean, including his 1927 flight from New York to Paris. The military considered making the Armbrust Cup standard issue for all its air pilots, but decided against it because the device was ineffective.The text printed on the front of the Armbrust Cup reads:"INSTRUCTIONSWhen in use: If possible, keep this cover constantly wet by frequent dipping or submerging.FOR USE IN MOUTHBlow through mouthpiece with enough force to send breath through cup. Always keep cup as cools as possible by best means at hand."The text printed on the back of the Armbrust Cup reads:"GENERAL INFORMATIONCup may be used submerged or in air at will. The quantity of water obtained depends upon the quantity and frequency of breaths blown through cup and temperature. Keeping cup as cool as possible by frequent dipping or submerging it in water greatly aids its efficiency."
