A representative from the library will demonstrate how a small 3 D printer works.  Since a small item takes a while to print, children will also hear Gentle Giant Octopus by Karen Wallace, and make an octopus craft while waiting.  Each child will be given a small item that was previously made by the 3 D printer.  Ages 8-11.  Registration is required and limited to 20 children.  Registration for this program begins May 15.
