Evolution of the bowling ball
As the beginning of the second video says, part of bowling’s appeal besides the mildly addictive part of many sports and games is its sameness; you’re suspended in or stepping back in time. But of course like all sports it’s evolved, with much of that recent. A ’50s ball didn’t hook compared to a reactive ball (which I don’t have) now. But bowling’s kept its style; the best of then and now.
