Safety

Wear eye protection and lab gloves.

There is a serious fire risk - a fire extinguisher should be ready. Make sure there is nothing flammable nearby.

Keep the test-tube at arm's length and keep the mouth of the test-tube away from you.

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

Reaction formula

CnH2n+2 + (2n+1)O2 → nCO2 + (n+1)H2O

Reagents

  1. Paraffin wax
  2. Water

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. Pour some water into a large beaker.
  2. Secure a test-tube in a jaw clamp and put some wax into it.
  3. Heat the test tube with a burner, until the wax fully melts.
  4. Abruptly put the test-tube down into the beaker with water. A huge explosion occurs.

Scientific background

Water is denser than melted wax, and when it is poured into wax, it goes down into the wax. Melted wax has a temperature above 200 °C, and water instantly vaporizes. Wax outbursts as small droplets occur. In this case the surface of the contact of wax and air is very large, and the wax spontaneously flashes.
