Learn how surfactants can protect us from germs with this fun experiment.
If you look around your home you’ll probably see hand soap, dish soap, and maybe even a bar of soap! In this quick and fun experiment, kids will learn how soap’s key molecules, surfactants, reduce the surface tension in water – and by doing that, they’ll understand the importance of washing their hands with soap to prevent the spread of germs.
