Chemistry Set
A chemistry set is an educational toy allowing the user (typically a teenager) to perform simple chemistry experiments. History Forerunners The forerunners of the chemistry set were 17th century books on "natural magick", "which all excellent wise men do admit and embrace, and worship with great applause; neither is there any thing more highly esteemed, or better thought of, by men of learning." Authors such as Giambattista della Porta included chemical magic tricks and scientific puzzles along with more serious topics. The earliest chemistry sets were developed in the 18th century in England and Germany to teach chemistry to adults. In 1791, ''Description of a portable chest of chemistry : or, Complete collection of chemical tests for the use of chemists, physicians, mineralogists, metallurgists, scientific artists, manufacturers, farmers, and the cultivators of natural philosophy'' by Johann Friedrich August Göttling, translated from German, was published in English. ...
