What are some weird/ random facts or statics?
Yes that you could, examine out Por-a-mold on Dick Blick's website. Also some regional art supplies shops raise both silicon mould kits clear resins. Anticipate a giant mess, however you are able to do it.
All the systems you specify are normally self-contained, electrically. They should all operate from batteries within their chassis, the batteries being continually kept charged by a connection to the building power. When building power fails, a relay in the emergency lights senses this and turns on the emergency lights, otherwise the systems behave as their name indicates, independently of building electrical operation.
