Abstract. The drinking bird toy is modified so that it operates using ice instead of liquids. It is shown how this and other modifications can be used in general and physical chemistry courses to illustrate a variety of thermodynamic concepts. Expressions are given for the maximum work in terms of the heat of vaporization or the heat of fusion. A sample calculation is given to compare the maximum work obtainable from equal amounts of liquid water and ice.
