My son is classic science geek - all things Physics and Chemistry.
We're recently found some great viewing common ground in Netflix's 'Baking Impossible' which pairs up a professional baker with an engineer, and they have to complete a series of tests where their creations are edible but functional - like a totally edible floating boat, or an assault course which a robot must navigate, protecting fragile bakes inside. They're scored on the baking but also the engineering.
It's naff and American but surprisingly watchable!
