Abstract. The number of first-year students of chemistry in Macedonia is declining in the last few years. An informal group (both teaching staff and Ph. D. students) called The Happy Chemists Group initiated the organization of a series of evening events with spectacular experiments, hoping to ‘infect’ high-school students with ‘the chemistry virus’. A demonstration with eight colorless liquids (based on various precipitates and complexes of lead) was introduced at the latest event that attracted students’ attention.

Key Words: Laboratories and Demonstrations; general chemistry; magic; precipitates; solubility product; lead; complexes
