I found this video interesting, now i'm curious as to why the ceramic capacitor seems to spring to life when it's cooled down?...
(I can't imagine this technique working on an electrolytic)

Yes it does.
Why would it?
Stick the electronics in a freezer = never break?
When you have a bad connection or high resistance somewhere, the cold causes the joints to contract a tiny bit, usually bridging a gap somewhere, so the connection is re-established.
In the case of bad electrolytics - ESR (Equivalent series resistance) is dependent on temperature, so a cold capacitor usually performs better than a hot one.
