Bye Bye Germs

Need a fun way to teach children why washing their hands is SO important? Bye Bye Germs gives a visual representation of what happens to germs when we wash our hands!

The Science:

When soap is added to the water the surface tension of the water is lowered. This causes the water molecules on top (where the pepper is floating) to "scatter" or move away to the edges. Just like what soap does to the germs on our hands!
