A Festival of Gravity

There have been reports of strange, unexplainable things occurring around Macclesfield recently.

Newly erected shelves falling down, washing falling from clothes lines, bathroom scales refusing to show weight loss... On Saturday night a person even stepped from a local pub and mysteriously fell to the floor.

Some rumours say that Macclesfield has more gravity than anywhere else in on Earth. Others say the gravity at Macclesfield is a smoother and more refined variety than the ordinary stuff found elsewhere.

They may sound crazy, but could these theories be true? Is there really something different about the gravity in Macclesfield? The time has come to test it out... with a gravity-powered go-kart race!

The Course

Vernon street is closed to traffic over the weekend of the Gravity Festival. The surface is sealed bitumen the length of the course, providing minimal resistance and allowing for high go-kart speeds! The track is more than 600 meters long, dropping an impressive 50 meters in altitude. Past entrants have clocked in at speeds in excess of 70 km/h!
