Leaping-Sliding-Sprinting-Riding Science Book
Lark/Sterling publishing. Bobby Mercer.
Have you ever wondered what it is that spitballs do - besides sounding gross- that make them illegal in baseball?
What's the secret to longer baseball hits and football kicks? Do you need more than strong legs to run quickly? Does making a racket while using a tennis racket make you a better player? Find out how the top athletes do what they do, with these activities.
The explanations come from science-chemistry, physics, aerodynamics, biomechanics, and more. So you'll be stretching your muscles and your brain.
