Because tennis balls are extremely hard to recycle and the industry has yet to develop a ball to make that easier, nearly all of the 330 million balls made worldwide each year eventually get chucked in the garbage, with most ending up in landfills, where they can take more than 400 years...
“The overall strategy is to use the waste hierarchy,” Davies said. “First of all, to try and reduce the number of balls that are being used. Then reuse balls as best we can. Recycling is third. And then disposing of balls is right at the bottom, the least desirab...
But creation isn’t the only goal. In fact, more important to Wittock is how her pieces are destroyed. At the end of her furniture’s life, Wittock can de-assemble the hundreds of tennis balls, which are woven together without glue, to be recycled, where the fuzz is burnt off and t...
Yep, tennis balls are much more abrasive than you think. And it gets worse. With continued use, dirt, rocks and sand become trapped in the fuzz, making it even more coarse. When your dog clamps down on a tennis ball, the fuzz rubs against your dog’s teeth, wearing them down. Over...
from 30% old tennis balls (any more would apparently cut into playability). And Wilson’s introduction of its Triniti ball, a still-pressurized model that has a sturdier core that leaks less and a tougher felt designed to be used for at least four outings without losing bounce or ...
Dogs are known to chase after and pounce upon tennis balls — often to the exhaustion of their humans, who are forced to toss the ball a hundred times. As a dog parent you can see the obvious thrill in your dog's body language when you throw a tennis ball. But have you ever wondere...
You'll notice that the results for the tennis balls are displayed under two headings "Laminar" and "Turbulent". Laminar and turbulent are terms which refer to the boundary layer of the fluid flow, which in simple terms is flow very close to the surface of a solid body. Laminar flow is ...
The distinguishing feature of a tennis ball is its filament surface that manifests as "fuzz" to the player. This fuzz dramatically alters the flight of the ball, especially compared to a smooth rubber ball. We used Penn ATP Extra Duty balls for all shots, as shown in Figure 7. The avera...
which is why the relationship works. Friends don’t drive each other to the brink of nervous breakdown just to win a match. I’m there to run. To rally. To crack wide the fresh can of balls. I’m playing authentically rather than playing to win. Which makes all our enterprises a lit...
He eyeballs Pedey, our little dog, and puffs himself up as if he’s going to attack that dog the way he pummels the crickets who are dropped into his tank. Thus, the need to procure crickets is a big one, and I haven’t been able to ride with her since my surgery. Yesterday ...
