_Place the capsule 
in a cool, dry location, where it
will not be exposed to great fluctuations in temperature.
Time capsules 
are most commonly found buried below
ground level in the foundations of buildings. A drained con-
crete or brick vault lined with fibreglass 
should be
built in order to minimise temperature fluctuations and
prevent access of water. The site of a time capsule is often
marked in some way. The International Time Capsule
Society exists to maintain a register 
of all known time
capsules, to promote research into the history, variety and
motivation of 
time capsule projects, to educate and
raise 
awareness of time capsules among the public and
scholarly community and to act as a clearing 
house for
information about time capsules.
