My boomerang will come back!
A festival family boomerang-making day combines physics with fun and a direct link to Isaac Newton.
Who would have thought that a boomerang's curving flight is down to the gyroscopic forces explored by Newton and defined in his Second Law of Motion?
For boomerang, read gyroscope, with aerodynamic forces generating a twisting movement which encourages a boomerang to move on a circular path.
Australia has become the boomerang's spiritual home and who better to lead the boomerang day than Australian expert Dr Hugh Hunt.
Forget the popular lament of 'my boomerang won't come back'. "That would be as silly as Robin Hood's deadly arrows coming back," said Dr Hunt. "Boomerangs meant for hunting were never meant to come back, it's only the modern design that we can design differently and have such fun with."
The boomerang making day is on Sunday 23 September, with bookable sessions at Grantham College.
