Sand soaked with ethanol is used as a burner for reagents – sugar and baking soda.
C2H5OH + O2 → 2CO2 + 3H2O
When the mixture sets fire reagents decompose and react with oxygen:
2NaHCO3 → Na2CO3 + H2O + CO2C12H22O11 + O2 → CO2 + 11H2O + 11C
The snake consists of sodium carbonate and black carbon particles.
