Studies regarding the whoosh bottle combustion experiment have largely focused on the detonation hazard of the demonstration, particularly with regards to fuel and container choice. Previous work has suggested that the fuel should be 2-propanol owing to its relatively cool flame characteristics. The current study has found that the combustion of 2-propanol in such fuel-rich environments creates significant levels of polycyclic aromatic hydrocarbons and other complex organic compounds. These materials pose a potential risk to the presenter and should be disposed of as hazardous waste. (Contains 1 figure and 1 table.)
