Tennis Balls

Regular tennis balls are pressurised for bounce and manufacturers aim to produce balls that can retain their bounce for as long as possible. Using nanotechnology, Wilson has done just that, introducing a double-core tennis ball, the inner core of which is coated with clay nanoparticles. Acting as a sealant, it makes it far more difficult for air to escape and the ball retains its pressure and bounce for twice as long as ordinary balls.
