Description
Did you know that the earliest known soap was made by the Babylonians around 2800BC, and this process remained almost unchanged until the late 18th century, when a method of producing large quantities of caustic soda was discovered?

In our case-lesson we reveal some "soap secrets" and refer to such school subjects as chemistry, anatomy, history and practice such skills as household, individual and teamwork, creativity and many others.
