Some nondescript boxes were being moved around the Da Vinci Science Center in Allentown on Friday, but soon, all will be revealed.

Crews shut down the science center for the day to set up the "Bodies Revealed" exhibition.

The traveling exhibit features real specimens to give visitors a 3D look at the human body.

The display is part of the science center’s "Year of the Human Body."

"Bodies Revealed" will opens at Da Vinci on October 6.
