Safety

Wear eye protection goggles. Ear protection. You need to be at a long distance from the ballon.

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

Reaction formula

CaC2 + H2O → Ca(OH)2 + C2H2

2 C2H2 + 5 O2 → 4 CO2 + 2 H2O

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. Obtain acetylene. Put several grams of calcium carbide into a flask equipped with venting with water. Also, acetylene may be taken from a cylinder.
  2. Fill the balloon with exuding acetylene.
  3. For a more powerful explosion, oxygen may be pumped from the cylinder. Also, oxygen can be obtained in a variety of other ways.
  4. Hold the balloon to a source of fire, while being at a long distance.
  5. Watch the explosion of acetylene.

Scientific background

Acetylene as an alkyne, it burns well in oxygen. Thus, a large amount of heat is produced. An explosion occurs at significant concentrations of acetylene.
