Butter not just for cooking

Some monks in China are proving butter isn't just for cooking.
The monastery in Northwest China hosted an annual butter sculpture exhibition Sunday.
The butter is colored and made into various shapes including Buddha, landscapes, animals and flowers.
To make sure the butter doesn't melt, sculptors have to constantly cool their hands by soaking them in freezing water.
Some have suffered severe arthritis because of the soaking but endure the pain to maintain the tradition of 400 years.  
The sculptures took three months to complete.
