Introduction: 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.
