About this deal
President of Coldiretti Ettore Prandini said: “The use of names alluding to the mafia is a business that causes serious damage to the image of Made in Italy by exploiting stereotypes related to mafia organisations, trivialising and quasi-normalising a phenomenon which has brought pain and grief across our country.”
A fizzy drinks bottle is used as these are designed to withstand pressures up to 20 atmospheres. Do NOT use a bottle larger than 500 cm 3. Use a heated cork borer of suitable diameter to cut a hole in the base of the plastic bottle so that the size 17 rubber bung fits very tightly in the hole.
Ensure the bottle is completely dry. Bottles should not be used after a demonstration without having been left inverted to cool and dry for at least 24 hours. Make a hole (approximately 5 mm diameter) in the base of the bottle. This can be done with a bradawl or with a glass rod, the end of which has been heated in a Bunsen. In front of the audience Make a ramp angled at approximately 20 o by propping the end on a number of textbooks. The area in front of the ramp should be clear for at least 20 m (you may need to perform this experiment outside).
The flash of the explosion can be seen if the room is darkened and is more easily seen if the bottle is transparent or 1.5 l PET carbonated drinks bottle, thoroughly dried. Look for PET on the bottle or the recycling symbol with a '1' inside. Teaching goals will vary with the audience. At its simplest level, this demonstration can show younger students how chemical reactions can release energy that we can use to do useful work, like driving an engine.In this ‘alcohol gun’ experiment, students observe what happens when a mixture of ethanol vapour and air is ignited using an electric spark inside a corked plastic bottle. The resulting minor explosion fires the cork across the room. Figure out the assembly as the figure...drill bunch of holes..tape and glue gun + CA to secure assembly.
