A 19L polycarbonate bottle for use in the 'Whoosh Bottle Demonstation'. The demonstration itself is visually impressive, showing how even small amounts of fuel can release a huge amount of energy. A mixture of alcohol and air are added to the bottle and then ignited. The result is a rapid combustion reaction, often accompanied by a dramatic ‘whoosh’ sound and flames. Different types of alcohol can be added to show differing effects: alcohol and ethanol produce a very quick 'whoosh' where as using propan-1-ol or propan-2-ol leads to a slightly slower reaction.
N.B. Only the bottle is supplied (without cap). The alcohol must be purchased separately.
