INNOVATION OF A FOOTBALL(BALL)

Introduction

What is a ball ? A ball is a round, usually

spherical but sometimes ovoid, object with various uses.

History AN IMPERFECT BALL Early soccer balls were hand-sewn and made of leather. They were never perfectly

round, and inflating them required some skill. The laces had to be undone before an interior air bladder was filled and tied with a thread; then the laces were retied.

In 1855, Charles Goodyear designed and built the first vulcanized rubber soccer balls (footballs).
