Did wicker help build Stonehenge?

For thousands of years, experts have debated how the huge stones that constitute Stonehenge were transported from Wales to their current site in southern England. Now engineer Garry Lavin has a new theory: wicker. (photo)

Lavin, who is from the Isle of Man, tested his theory by wrapping a 3/4 ton stone in basket-woven willow and hazel and rolling it down the hillside. "I packed the gaps inside with reeds and rolled it down a hillside. The stone fell out at the bottom but my construction was still intact. The project was then taken to the edge of the local canal and pushed in and it floated with about an eighth of the mass protruding above the water, but easily towable along the canal," he said.
