The main tank contained an answer of sodium bicarbonate in h2o, whilst the interior container (relatively greater compared to equal in the soda-acid device) contained an answer of aluminium sulphate. When the methods ended up blended, ordinarily by inverting the device, the two liquids reacted to produce website a frothy foam, and carbon dioxide gasoline. The gasoline expelled the foam in the form of a jet.
