Hydrogen and oxygen in a tube

Detonation of hydrogen and oxygen in a long reinforced tube


Fire and Flame 24 - Hydrogen Oxygen Tube

by Royal Society Of Chemistry


Wear lab gloves and eye protection. There is a serious fire risk - a fire extinguisher should be ready. The mixture of hydrogen and oxygen is dangerously explosive!

Always follow general safety recommendations. Please note that conducting chemistry experiments you must comply with the relevant legal procedures in your country.

Reaction formula

2H2 + O2 → 2H2O


  1. Hydrogen
  2. Oxygen

Step-by-step instruction

WARNING! This experiment is dangerous! You should NOT perform this at home. ONLY carry out this experiment, if you are a trained chemist, and you understand local safety and legal requirements, which are required to perform such experiments

  1. Fill a long reinforced tube with the hydrogen and oxygen mixture and close it with a stopper. The ratio of the components should be 2 hydrogen volumes per 1 oxygen volume.
  2. Carefully open one of the ends of the tube and bring a burner. An explosion, followed by a loud bang, occurs in the tube.

Scientific background

Hydrogen reacts with oxygenproducing water. This reaction is very vigorous, and the flame spreads rapidly in the tube.
