Tennis ball game, a good lean continuous improvement exercise..

http://leaninsider.productivitypress.com/2008/12/tennis-ball-exercise.html

When I played this game for the first time in the class, it generated interest and a group of students who were really ingenious, came up with the rolling of the tennis ball making use of gravity to teach the minimum time of 1.3 seconds..

Was useful in spreading the idea of Kaizen or continuous improvement to the students. I just had to tell them what needed to be done and they did it in the shortest time..

Good work, students !!
