Greetings If you cannot read this newsletter, please visit our Robo-Pong web site. You are receiving this because of your interest in the game of ping pong/table tennis. Newgy Industries is the world's leading manufacturer of table tennis robots: our Robo-Pong line of robots is for recreational and expert players alike.
Ping pong balls are made out of plastic. Right? Wrong. They are made of celluloid, a colorless flammable material composed of nitrocellulose and camphor, the same ingredients used to make photographic film. Hence, reels of movie film and ping pong balls are made of the same stuff! Celluloid is used because it provides a stronger bounce than plastic. Ping-pong balls are very stiff and springy, and they lose only a small fraction of their energy when they bounce on a hard surface. PS: In the Jan/Feb, 2005 issue of USATT Magazine there is a very interesting article about how ping pong balls are actually made.
Did you know you can wash ping pong balls? Actually, we advise it whenever you use new balls in a Robo-Pong. Why? When manufactured, ping pong balls have a powdery residue on the outside. Washing the balls in soapy water and drying them helps to remove that residue. Then run the new balls through your robot at high ball frequency to help "rub down" the outer surface. This "wash and rub-down" procedure will assure that you get the best performance from your Robo- Pong robot. And washing the balls periodically will reduce the amount of lint and other dirt that gets inside your robot and reduces its performance.
Here's the quiz for you math types to figure out how many ping pong balls will fit in your recreation room or any given size room: http://www.engr.sjsu.edu/nikos/courses/engr 10/pdf/pingpong.pdf Here are some other fun "ping pong" experiments for kids and adults: http://ww w.sdtta.org/science.html
Ping pong ball brands are provided in different quality levels determined by seam quality, roundness and consistency from one to the next. Competition balls are evenly constructed to allow the most true flight and bounce. Three star balls are the highest quality balls and are the only ones that can be approved for official tournament play. Two star balls are the highest grade "practice" or "recreational" ball. One star balls are the lowest quality in star graded balls. Non-graded balls are most likely to have irregular seams and be inconsistent in size and bounce.
A few years ago colors started changing in the very traditional world of "table tennis"--from green tables to blue and from white balls to orange--both moves to improve the overall visibility of the balls as the speed of play has dramatically increased. But the other huge change came with the advent of the 40mm ball. You can still play with 38mm, but the International Table Tennis Federation adopted the 40mm balls as its official size five years ago. The larger ball is now universally used in all officially sanctioned tournaments. When the size of the table tennis ball increased from 38mm in diameter to a larger 40mm, the weight also increased by 2.7 grams. And that relatively small change in diameter increased the volume of the ball nearly 20 percent! Why go to the 40mm size ball? It was experimental for a few years, but was adopted to improve play for all levels of players. Larger size balls encourage longer rallies for all players and increase the visibility of the ball for television as the game has become more and more popular worldwide. Since 40mm balls don't rebound as fast as the smaller balls, players must supply their own power and be more active when blocking. And because the larger ball slows down faster due to air resistance, players who play off the table have had to adjust their instinct for how far they play from the table--and typically play a bit closer. The 40mm ball spins less, particularly on slow moving shots like the serve. Therefore, serves have become easier to return--and placement even more important.
