The Pennsylvania Farm Show unveiled a sculpture Thursday that gives new meaning to the term "heavy cream."

A 1,000 pound work of art featuring two dancing cows next to three human beings drinking milkshakes is made entirely out of butter. Its theme is "Shake, Rattle and Roll," which is a hit song from 1954 — coincidentally, the same year the Farm Show unveiled its now-famous milkshake.

"For 60 years, milkshakes have been part of the Farm Show tradition of celebrating Pennsylvania agriculture," said Greig. "What may seem like just a great drink in a plastic cup is a lot more – it's a representation of the state's 7,200 dairy farm families who grow Pennsylvania by driving the economy, creating jobs and supplying quality products to consumers."

The sculptor, Jim Victor, is from Conshohocken. He began building the butter mold in mid-December and finished just in time for the show, which kicks off Saturday and runs through next Saturday, Jan. 11. It's in  98th year and is held in Harrisburg.

A time-lapse video of the construction of the unusual sculpture is below.

The event will include 6,000 animals, 10,000 competitive exhibits and 300 commercial exhibits. It is free to the public and nearby parking is $10. For more information, visit the Farm Show's website.

At the close of the show, the butter, donated by Land O' Lakes in Carlisle, Cumberland County, will be given to a Juniata County dairy farm. The butter will be put through a digester and converted to about 65 kilowatt hours of electricity to help operate the farm.
