If a full range of experiments is desired, the time taken could amount to 30 minutes, but this may not be justified in terms of the learning objectives concerned. Each experiment should take no more than two minutes, though the cleaning of the beaker between experiments may take up more time than expected. This is a series of quick, simple, class experiments which can be extended or shortened as desired.

Finally the same experiments can be repeated using samples of hard water to compare the effects. A needle can be carefully floated on a clean water surface and the effect of adding detergent or soap observed. This can be repeated with other powders after cleaning the beaker and using fresh water samples. RSC Yusuf Hamied Inspirational Science ProgrammeĪ fine insoluble powder, such as talcum powder, is sprinkled on a clean water surface in a beaker, a drop of detergent or soap solution added to the centre, and the effect observed as the surface tension of the water is changed.
