Fire seems to slide into bottle in fun chemistry experiment

The video above shows a really cool chemistry experiment using just a large bottle, alcohol and fire. Already in the experiments below, it is shown what happens when the bottle is still capped with hot air:

Called the "whoosh bottle", the experiment needs a bottle containing air and alcohol, which will give rise to a quick and incredible fire that slides down the wall of the container and is determined by the concentration of the flaming liquid.

It is important that the hull be made of polycarbonate so as not to risk fire or explosion. Also, it is crucial that you do NOT try this at home !

Also watch three simultaneous experiments done with different concentrations of alcohol - which creates flames of varying intensities.

The experiment is complete only if it has the characteristic noise, called "whoosh". It demonstrates the large amount of chemical energy that is released in the combustion of an alcohol. Cool huh?
