A trebuchet, used in the Middle Ages to siege enemy castles, will make a return to Rocklin Mini Maker Faire this year! Leo A Palmiter Trebuchet Team built one capable of hurling a bowling ball the length of a football field.

Come by Rocklin Mini Maker Faire on Saturday, October 14th at Sierra College to see this trebuchet throw pumpkins & melons at predetermined targets to demonstrate the function of gravity, kinetic energy, and centripetal force.

Watch it in action! This awesome video produced by Gabe Flores!
