Hand washing with soap
Hand washing with soap is shown in three steps. The microscopic processes during the washing process are illustrated in an animation.
At the end, the “Details” button can be clicked to show an animated microscopic view of the processes that occur during hand washing with soap. The animation shows how the anionic surfactants contained in the soap act on a dirty spot: The dirt is “broken up” and the individual dirt particles are surrounded by the surfactants.
