How Bowling Balls Are Made

I have been a fan of how things are made videos since my Mister Rogers and Sesame Street days, so I was not expecting to be so surprised watching the video above about how bowling balls are made. It’s a ball — how complicated could it be? Well, it turns out that modern bowling balls contain an asymmetric weight block in the middle that looks a little like a car’s starter. Weird, right?

As I started to wonder why it would be advantageous to include such a lopsided core in a ball you want to roll predictably down a lane, I noticed YouTube’s algorithm doing its job in recommending that I watch Veritasium’s recent video on How Hidden Technology Transformed Bowling, which totally explains the wonky weight block thing:

The weight blocks are wonky in a precise way. They’re designed to cause the ball to contact the lane over more of the surface of the ball, giving it more traction once it hits the unoiled part of the lane, which is desirable for expert bowlers looking for a wicked hook. So cool! (thx, mick)

Update: Brendan Koerner wrote a piece for Wired several months ago about Mo Pinel, who revolutionized bowling with the asymmetric cores described in the video above.

Pinel toured Faball’s factory and examined a freshly made core that the company used in its Hammer brand. It had a symmetrical and unexciting shape — the center looked like a lemon, and there were two convex caps of equal size on either side. In a moment that has now passed into ball-design legend, Pinel grabbed the core, which was still soft because the polyester had yet to cure, and sliced off the ends with a palette knife. Then he smooshed the caps back on into positions that were slightly askew, so that the contraption now looked like a Y-wing fighter from Star Wars.

The ball that contained this revamped core, the Hammer 3D Offset, would become Pinel’s signature achievement. “That ball sold like hotcakes for three years, where the average life span of a ball was about six months,” says Del Warren, a former ball designer who now works as a coach in Florida. “They literally couldn’t build enough of them.” In addition to flaring like few other balls on the market, the 3D Offset was idiot-proof: The core was designed in such a way that it would be hard for a pro shop to muck up its action by drilling a customer’s finger holes incorrectly, an innovation that made bowlers less nervous about plunking down $200 for a ball.

Crouching government, hidden compartment

Alfred Anaya was really good at putting secret compartments into cars and he thought he was in the clear if he didn’t know what his customers were putting in these compartments. He was wrong.

Alfred Anaya took pride in his generous service guarantee. Though his stereo installation business, Valley Custom Audio Fanatics, was just a one-man operation based out of his San Fernando, California, home, he offered all of his clients a lifetime warranty: If there was ever any problem with his handiwork, he would fix it for the cost of parts alone-no questions asked.

Anaya’s customers typically took advantage of this deal when their fiendishly loud subwoofers blew out or their fiberglass speaker boxes developed hairline cracks. But in late January 2009, a man whom Anaya knew only as Esteban called for help with a more exotic product: a hidden compartment that Anaya had installed in his Ford F-150 pickup truck. Over the years, these secret stash spots-or traps, as they’re known in automotive slang-have become a popular luxury item among the wealthy and shady alike. This particular compartment was located behind the truck’s backseat, which Anaya had rigged with a set of hydraulic cylinders linked to the vehicle’s electrical system. The only way to make the seat slide forward and reveal its secret was by pressing and holding four switches simultaneously: two for the power door locks and two for the windows.

Esteban said the seat was no longer responding to the switch combination and that no amount of jiggling could make it budge. He pleaded with Anaya to take a look.

Anaya was unsettled by this request, for he had suspicions about the nature of Esteban’s work. There is nothing intrinsically illegal about building traps, which are commonly used to hide everything from pricey jewelry to legal handguns. But the activity runs afoul of California law if an installer knows for certain that his compartment will be used to transport drugs. The maximum penalty is three years in prison. Anaya thus thought it wise to deviate from his standard no-questions-asked policy before agreeing to honor his warranty. “There’s nothing in there I shouldn’t know about, is there?” he asked. Esteban assured him that he needn’t worry.
