What should I do with the key?

[CrackersofGraham]

Hey everyone! I just got myself a brand new chain to lock around my neck! I can't slip it off, and I also found that I can hide it from suspecting eyes by tucking it into my shirt! So, I was a wee bit curious as to what to do with the key!

Quick note though, I'd rather not destroy it (which is rather obvious), and I can't mail it to myself because the post service sucks where I live and I might never see the damn thing again. Other than that, go wild!

Go to a place you know is closed for [x] days (e.g. closed at weekends). Hide the key somewhere at this location (within the walls of the shop/museum/etc) just the day before it'll be closed for [x] days. When it closed, you cannot retrieve the key for [x] days.

Note: make sure it is well hidden so guards, shop owners or whoever walks there doesn't find the key and takes it.

Get a water bottle (or Gatorade bottle if the key is to fat to fit through a water bottle). Piss in it until it is full. Drop the key in and then freeze it.
