The Wiffle ball was created to replace baseball, stickball, and softball in back yards and city streets for boys and girls. It is constructed of a durable rubbery plastic, is low in weight, and cannot be thrown or struck far. The Wiffle ball is also a good indoor ball. In fact, it was originally designed for use by children inside buildings where there were no playground equipment available. It may seem obvious, but the Wiffle ball is very light weight. A typical Wiffle ball does not weigh more than 3/4 of a pound (0.35 kg). This makes them easy to handle but still provides enough resistance when hit that young players do not injure themselves by throwing them too hard. Wiffle balls are available in various colors and styles including red, white, blue, green, and yellow. They also come in different sizes with two standard models currently on the market: the small Wiffle ball (3 inches or 7.5 cm in diameter) and the large Wiffle ball (4 inches or 10 cm in diameter). While they are easy to throw and catch, Wiffle balls are difficult to hit because they travel so fast when thrown. This means that skilled players are needed to take advantage of their lightweight nature and use their speed to get extra bases or beat out defensive plays.
