In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution. The goal of this activity is to provide an interesting experiment which learners of many different levels can perform. The write-up for this activity provides explanatory information that presents the experiment from several different perspectives. This activity includes an introduction to common sugars, as well as some discussion of temperature and thermometry, basic thermodynamics, and the experimental procedure to make the candy glass.
