Try the experiment
Over the last 18 months, washing our hands has been more important than ever. It's vital to stop the spread of diseases like COVID-19.
However, did you know that 2.3 billion people in the world – that's almost one in three of us – don't have soap and water to wash their hands at home?
This experiment is a great way to get young people talking about handwashing, as well as introducing them to the science behind it through fun, practical learning.
