The precise composition of Floo powder is a closely guarded secret. Those who have tried to ‘make their own’ have been universally unsuccessful. At least once a year, St Mungo’s Hospital for Magical Maladies and Injuries reports what they call a ‘Faux Floo’ injury – in other words, somebody has thrown a homemade powder onto a fire and suffered the consequences.
