Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). ... This experiment can be carried out conveniently in groups of two or three and takes about 40 - 45 minutes...

Calcium oxide reacts with ammonium salts or with proteins to liberate ammonia gas (NH3). An experiment from a 1960's Chemcraft set had the experimenter place fingernail clippings and calcium oxide together in the hand.
