Cow's Digestion Shown with Rude Goldberg Machine

Cows are famous for having four digestive systems in their body and f you've ever wondered just how they use these to digest food then this Rube Goldberg will give you the answers.

It was created by Nova Jiang and is basically a wooden machine that represents the digest tracts of a cow.

A small ball is placed in one end of the machines - it's chews a few times before it's passed onto the next stage in a cows digestive systems.

It's an interesting idea and we think it could work even better if there was some text added to explain exactly what processes people are seeing.
