Liquid Nitrogen "Smokey" Cocktail Perforates Woman Stomach
An 18-year-old has had to have her stomach removed in an emergency operation after drinking a cocktail containing liquid nitrogen.
Gabby Scanlan from Lancaster was out celebrating her birthday when she fell ill.
The bar which sold the cocktail has said it has now stopped using liquid nitrogen, which creates a smoky, dry ice effect.
