-
- A: This is a large plastic bottle filled
with ice. Do not use glass bottles as they will break when the
ice is formed.
-
- B: This is a piece of chain. The chain
should be inserted into the bottle before the bottle is placed
in the freezer. Make sure there are at least 40-50 centimetres
of chain sticking out at the top of the bottle.
-
- C: This is the keys to free yourself and
to the padlock at "D" securely attached to the chain
and securely frozen in the ice. Make sure to leave the padlock
unlocked when you freeze the bottle.
-
- D: Lock the frozen bottle around some
secure structure with a padlock. Do not lock it to a radiator...
-
- When the ice finally melts, it is possible
to pull out the chain and get access to the keys.
-
- Additional Information.
Changing the size of the bottle
changes the time needed for release. Make sure the chain and
key can slide out of the bottle opening without getting stuck.
