Get put in jail, hide pen in wall of cell. Get put back in jail 49.5 years later and recover pen
Give it to someone more responsible than me
Implant into body
Bluff the evil forces – just hide in plain sight, use it every day
Give it to the queen to store with the crown jewels
Turn it into an art sculpture, hide in plain sight
Melt down, remanufacture when required using the melted remains
Keep it in my pocket
Hide it in a sewer
In a crypt
Behind a brick in the great wall of China
Inside Fort Knox (or wherever gold reserves were held at the time!)
Underwater
Sole of a shoe
Get the president to sign something important with it, get it put in a museum under guard
Mould it inside a brick
Hide in the masonry of Pont des Invalides (or other 1855 structure of your choice)
Inside a statue
Inside hollowed out book
Behind false wall
Change appearance of pen (different colour?) as long as it is reversible
Inside a clock
Ways to make sure it gets to him if I die:
Start a conspiracy to keep it
Publicise to world what is happening, bring the evil forces out into the light
Hide it at the end of a treasure hunt with each clue more fiendish than the last. If you die, make sure Einstein gets the first clue, he can take it from there
Hide it in the Bern patent office in a packet with his name on it
Write a set of instructions on how to get the pen, give letter to Western Union to guarantee delivery at the correct time
Go to Colorado, hide addressed envelope with Brachiosaurus fossils and re-cover the fossils, ready for them to be dug up in 1903.
Ways to confound evil forces:
Learn how to lose a tail when on my way to hide the pen
Pretend to hide it in multiple places
Pretend to give it to multiple people so they don’t know who to follow
Go all-out attack on the evil forces
Put booby traps around hiding place
Put booby traps elsewhere to misdirect
Make multiple indistinguishable copies and hide all of them
Ensure evil forces don’t know I ever had it
If unsuccessful, give it to someone else, commit suicide so they can’t find out who I gave it to
Other:
Don’t worry about it, he can probably use whatever pen and still get the same result
Otherwise, use magic pen to try to write miracle papers myself
Buy lots of identical pens which will work just as well
Reverse engineer pen if no similar pens available
Apply magical foresight to foresee all attempts at theft and prevent them
Rely on determinism – apparently I already know he will write with this pen
Use my knowledge of modern technology to make loads of money to help with effort
Hide it in one of infinitely many sets each of which contains infinitely many elements, await for Ernst Zermelo to formulate his axiom of choice (1904) to allow me to arbitrarily pick it from the relevant set
Places to hide:
Buried (waterproof box)
Inside a wall cavity
Bank safety deposit box
Attic
Inside hollow tree
