Engineer Tom Stanton is fascinated by the way in which flywheels can store up energy as they’re spun up to speed. In this clip, he combines a flywheel mechanism with a sturdy aluminum trebuchet, creating a durable machine that can toss a tennis ball at fast as 180 mph.
THE BEST Tennis
A look inside a factory in China where Artengo’s tennis balls are made. First, sheets of rubber are cut into pellets, which are then molded into semi-circles. Then, the sections are combined, hand-wrapped in felt, and then heat-sealed together. Watch them make their rackets here.
The Beyond the Press channel took a powerful Gardner Denver air compressor and connected it up to a simple rig they built for firing tennis balls. It isn’t particularly accurate, but we still wouldn’t want to be on the business end of this thing. Test firing starts at 4:15, but it gets better.
It’s Spring, which in the Midwest means go play outside. How about tennis? Graphene and Kraibon for killer shock absorption in Head’s new Instinct line means great touch, power and maneuverability. Try the Adaptive version with a kit to tune the stick to your personal specs.
The lightweight Head Nitro Pro gives great support and looks sweet whether you’re on the court or on the street. It keeps your feet at an optimal temperature too, with a unique cooling system integrated into the sole. Pair these with the Radical Pro and you’ve got serious game.
Summer is here, so it’s time to take Head’s Graphene XT Radical Pro for a spin. The frame feels like a sports car – fast, powerful and stiff – so you can confidently smash crisp shots to the baseline and hit stable volleys while effortlessly befuddling your opponents.
