It sounds weird to me some stuff you wrote. As far as I know, "Thus" is used for conclusions in the past. Ex. The troops fought to a standstill, thus no winner was declared.
Unlike "Hence" which is used for future. Ex. I'm broke, hence I will walk rather than taking the bus.
Don't forget the word "Thereby", which is very important as well. In the case: ": This thing is a balloon, and thus is made of rubber and inflates when you blow into it." It would sound better if we say "...and thereby is made of rubber..." since "Thereby" means "Because of...". But I'm not sure. What do u think?
