A plastic ruler rubbed on wool fabric deflects the stream of water coming from the tap. The photo on the worksheet shows this clearly. The students should conduct this experiment and then explain what forces are at work and how the deflection comes about.
Incremental hints for answering this task are available under “Bending water (hints for printing)” or “Bending water (interactive hints)” on the media portal of the Siemens Stiftung. The worksheet includes QR codes for downloading the interactive hints and viewing the solution.
Explanations of the experiment for the teacher are found in “Bending water (teacher information).”
