- Gasogene
The gasogene (or seltzogene) was a late Victorian device for producing
carbonated water .It consisted of two linked glass globes surrounded by a
wicker or wire protective mesh because they tended to explode. The lower contained water or other drink to be made sparkling, the upper a mixture oftartaric acid andsodium bicarbonate that reacted to producecarbon dioxide . It is asiphon in that the produced gas pushes the liquid out of the device.The gasogene features as a cryptic residential fixture at
221B Baker Street inArthur Conan Doyle 'sSherlock Holmes stories.References
