I always wanted to work on a chocolate factory
Manufacturing chocolates using machinery seems like it would be fun.
Can you imagine how good it smells over there? 
Imagine how their warehouse smells where they keep their chocolates and equipment used for assembly line production.
I bet it smells sweet and delicious :) What equipment is used at the factory?
Well factories that manufacture chemicals usually have tanks and pressure vessels.
how interesting. i would like to know more about factories
Early factories that only have a little bit of machinery, and a small amount of employees were called "glorified workshops".
