Description of the Experience

Baking soda placed on a paper napkin
A perforated cork or plasticine
A drinking straw
A small water bottle (dry )
A bit of sewing thread


4 tablespoons of baking soda in the napkin, close and tie with string -shaped bag (it must be properly secured ) . Place 5 tablespoons of vinegar into the bottle. Put the baking bag inside the bottle deformed hang (with a portion of the wire out) and do not touch the vinegar. You take the cork or clay and place the straw in the mouth of the bottle.
Stir the bottle , covering the straw with your finger and holding the bottle while mixing baking and focuses the gas coming out of the bottle over a candle with vinegar ( without uncovering the straw ) . Remove your finger and focuses the gas coming out of the bottle over a candle .


The reaction between bicarbonate (a base) and vinegar ( weak acid ) form carbon dioxide which fills the vessel and out through the straw. As it is heavier than air , facing the candle expels oxygen. Without oxygen the flame goes out ,


Dissemination Seminar in Florence

31 October 2015 The seminar has been held in ITIS “A. Meucci” one of the schools involved within Goerudio project activities. Its main aim was to promote the results of the project toward a broad sample of stakeholders even overcrossing the number of people directly involved in the production of project outcomes. This purpose has been totally achieved especially thanks to the participation of students and teachers coming from different schools or from other classes instead of those ones directly involved within the project activities.
