> Because the butter used for the Iowa State Fair's cow sculpture is recycled for many years, the cooler where it's made has a funky smell that most fairgoers would never know about on the other side of the display glass.
The fact that they recycle the butter for about a decade is reassuring though. A full cow worth of butter yearly just sounds wasteful, but this approach scales that back to a tenth of a cow.
Say $5/lb (retail price, surely they don't pay this): $3000 for 600lb.
Using cost as a proxy for the intrinsic value of things, I think just the glass in a cow-sized display case will be more than that, let alone with a refrigeration system built into it.
And if we want to go further, think of the embedded costs of the building it's in, and then include staffing, energy, maintenance, etc that's being "burned" by this exhibit!
