Thousands of years from now archeologists will be puzzling over the odd shaped, translucent red vessel found deep in a volcanic crevasse. Is it a cocoon or egg of an alien insect creature?  A time capsule?  The scat from a here-to-for unheard of creature?  Nope, it just the water bottle that escaped from the backpack pocket of this clumsy explorer.  It never even bounced but fell right to the bottom of a narrow, deep crevasse where there was no hope of retrieving it.  Drat.
