Jul 8, 2016 at 9:34 comment added DrBob @ApproachingDarknessFish Salt water or saliva would be fine, as would anything with water in it - milk, orange juice, the finder's own blood. If it is frozen in a glacier or icecap, just use melted ice (sea ice or freshwater ice). It is the physics rather than the chemistry that might defeat Fred's tech - you need to be able to generate a vacuum.
Jul 7, 2016 at 23:12 comment added ApproachingDarknessFish @DrBob I guess it doesn't have to be liquid when it's found as long as it be quickly converted back to liquid. Would salt water of saliva be acceptable re-hydration methods? Fresh water is in extremely short supply. Freeze-drying is a stretch; I'd probably have to rely on seriously hand-wavy chemistry to make that happen.
Jul 7, 2016 at 19:17 comment added DrBob The 'has to be liquid' bit is stumping me. Otherwise I'd suggest letting it sit overnight to let the red cells settle out and clot (it forms a jelly-like lump at the bottom of the jar). Then freeze dry it and put the powder in the local glacier. Does the finder have to find liquid, or can they add water to rehydrate stuff? Though freeze-drying might be beyond Fred's technology...

Jul 6, 2016 at 21:57 comment added Bellerophon Think your best option is to bury it in ice, some ice cores have lasted for 100s of years. Might need defrosting but other than that should be good. Wouldn't work as actual blood of course but should taste and look right. Someone feel free to write this up as an answer.
Jul 6, 2016 at 21:53 comment added ApproachingDarknessFish I think freezing is definitely feasible. I don't know about vacuum sealing... maybe, I don't know how to accomplish that chemically (and the mechanical equipment to accomplish that definitely isn't available). Sterilization is definitely possible.
Jul 6, 2016 at 21:51 comment added AndreiROM Unless you can freeze or seal it I honestly can't imagine what you're expecting.
Jul 6, 2016 at 21:45 comment added Nathaniel Ford Is freezing an option? Is a vacuum-sealed container an option? Can the blood be sterilized, to kill off anything that might cause it to break down going forward (assuming you can otherwise seal it off)?
