The second video from Pat – “For the outdoor tennis players out there, the season here in the Mid-Atlantic is in full swing (get it…?), so our thoughts turn to whacking the fuzzy ball. This is another video from our friends at South Carolina Educational TV. It’s a 7-1/2-minute tour of a Wilson tennis ball plant. Wilson Sporting Goods is the world’s largest manufacturer of tennis balls. The video follows the ball through the process from slugs to half-shells to the core and finally to the application of green felt to the outside. This one plant makes 90,000 dozen balls a week, over 50 million a year. Incredible.” – Link.
