[header] How to serve a ping pong ball with a topspin [title] Serve a ball with no spin. [step] This ball will not travel as fast, but if you are just learning how to play ping pong, it is important you can do this first. [substeps] Hit the ball near its equator, which is the line just through the exact center of the ball. 
Make sure you hit it with your racket at a 90 degree angle to the ball. The ball will travel forwards and have little to no spin.
