How many H0 trains...

...do you need to pull a car?
This was a silly question at the Saturday evening show "Ask the Mouse".
My Hanullis were over the moon about this. H0 a seize of the model railways (1:87) and it is also their seize. 
If you are interested, you can watch here what inventions were necessary to answer the question. They had help from the makers of the fabulous Miniatur- Wonderland in Hamburg.
Spoiler-alert: 
They needed 84 locomotives to pull a aproximately 1200 kg car.

Thank you admirer for hosting Silly Saturday :-)
