Big!
Big! is a TV series in which an episode consists of a team of engineers manufacturing the world's biggest items (usually a household item that's normally hand carried, scaled up to proportions that make the items unusable without JCBs and Cherrypickers) for the sake of setting world records.
The devices have to function to qualify.
The series originally aired on Discovery Channel in 2004. It is currently airing on The Science Channel weekday mornings.
