Don’t know what to do with all those pumpkins after Halloween? The answer is Cary’s GREAT PUNKIN’ CHUCK. It’s a mash up of science, back-yard technology and good clean fun hurling pumpkins with trebuchets at targets and for distance.

Teams compete for prizes (and glory) on Sunday, November 3, 2013 at Fred G. Bond Metro Park in Cary, NC. Spectators can enjoy the thrill of competition and a mini-makers’ fairewith science and technology exhibits for young and old.

Cary’s GREAT PUNKIN’ CHUCK is a partnership between TechTank and Town of Cary.
