Bubble Shock!

The Bane attempted to use the orange-coloured Bubble Shock! soft drink in order to control the Earth's human population.

Bubble Shock! in fact contained secretions from the Bane Mother. When consumed, the secretions of the mother entered the body of humans, allowing the Bane to control them. Sarah Jane Smith's technology even detected the drink as an alien life form in its own right, and she also mentioned that a bottle of the drink resisted an attempt to analyse it by some scientists. A free bus took children to tour the Bubble Shock! factory. Upon entering the building, the children were analysed by a scanning device. These analyses served to create the Archetype, a human child grown by the Bane to determine why 2% of the human population had an immunity to the enzyme. The machine however was disguised by name as an alarm system and metal detector to stop children from attempting to find out about its true purpose.

History
Bypassing the variety of approvals required, the Bane managed to get their product released in two weeks, much quicker than European Union food and drink safety policies would normally have allowed. Advertising the drink as delicious and organic and saying it contained an ingredient called Bane, the Bane species heavily advertised the drink on television. They even had Blue Peter presenters Konnie Huq and Gethin Jones offer on-air testimonials. 98% of the human population found the drink delicious and drank it extensively, but the remaining 2% found it disgusting, like Maria Jackson.

Pushed into a corner, Mrs Wormwood, the leader of the invasion, turned Bubble Shock! consumers into possessed slaves who forced the drink on anyone who had not already taken it. With the death of the Bane Mother, however, the drink apparently lost its power. Afterwards, the possession of various humans was attributed to the ingredients in Bubble Shock! causing a combination of "chemical imbalances" and Bubble Shock! was promptly removed from the public domain.

Sarah Jane mentioned that the Bane were behind the Bubble Shock! incident when facing them once more alongside Rani Chandra. Rani herself remarked that she thought it was foul, indicating that she was part of the 2% who were incompatible with the Bane secretion. ( TV: Enemy of the Bane)
