How do you demonstrate table tennis?

Answer 1

If I understand your question, the best way is to show what is referred as 'stroke technique'. For example: forehand to forehand topspin, backhand to backhand topspin, forehand to forehand push/underspin, backhand to backhand push, and so on. This way, the ball is keep in play for a longer period of time so as to demonstrate the technique that is needed to master it.
