La “bottiglia zampillante” di Anacleto 2003

Every year the Olympiad Group of the Association for the Teaching of Physics suggests to high school students a non-competitive physics test, the ‘Anacleto Games’. The test consists in answering a series of questions and making an experiment. Although the activity is suggested at a very elementary degree, a mere knowledge by heart is not sufficient to answer the questions nor a simply executive receipt is suggested to make the experiment. In this article we describe the simple model of classical Mariotte Bottle suggested in the experimental test of 2003 Anacleto Games and report some results got in the schools where the test was made and the comments by the teachers taking care of the organisation and valuing students’ work.
