Racing boats: The science of surfactants

The present module deals with the analysis of surface tension, as it varies with two surfactants; liquid soap and detergent and with the increase of temperature. Therefore, first the experiment will be performed in water at room temperature and then in warm water. The experiment consists of moving a boat (of disposable plate material), by the action of the surfactant's force with the water molecule.
