Summary

[edit]
Description
English: This picture was taken during a lab experiment at school, with the students of my second middle class (12 years old). I teach Mathematic and Science in the Parini-Merello Middle School in Genoa, Italy. The experiment was about the discovery of a chemical reaction, and the students were astonished about the gas formation in the tube with sodium bicarbonate and acetic acid.
