AB  - Those who have had contact with the teaching of physics in schools will be familiar with the many attempts which have been made to time freely falling bodies. These include the use of smoked plates and tuning forks, darts and gramophone turn‐tables, and, more recently, tape recorders and scalers. Some have been highly ingenious attempts and have, generally in the hands of their inventors, given good service in schools. None, however, has met the twin requirements of cheapness and classroom viability without which the most ingenious apparatus can never gain more than a limited circulation. It was to meet these requirements that the Venner clock was designed FIGURE 1.
