Experimenting: Yeast, Hydrogen Peroxide Chemical Reaction (fire)

Experimenting with Yeast and Hydrogen peroxide. When Hydrogen Peroxide (2 H2O2) reacts with yeast it makes water (H2O) and Oxygen (O2) 2 H2O2 -> 2 H2O+O2 im just board and want to share my chemical reactions with others.
It relights the piece of wood because the air inside the cup is so rich it changes the flash point (correct me if im wrong)
