Non-Flammable Hand Experiment

The Non-Burning Hand Experiment

The non-burning hand experiment is a striking chemistry demonstration in which flames are applied to the hand without causing injury. It is commonly used for educational displays to introduce concepts such as heat combustion and gases. During the experiment, brief flames appear on the hand but the hand does not burn. This experiment can be dangerous if not performed carefully.

What Happens in the Experiment?

In this experiment the hand is first dipped into water and then into soapy water. Afterward a layer of soap bubbles containing a flammable gas such as methane or hydrogen is applied to the hand. When the bubbles are ignited only the gas burns. The hand remains unharmed because it is wet. The flame extinguishes within a few seconds and the hand emerges without damage.

Scientific Explanation of the Reaction

The flammable gases contained in the bubbles methane or hydrogen release heat and light when ignited. However the layer of water on the hand acts as a thermal insulator protecting the skin. Additionally because the flame rises upward it does not make direct contact with the hand. For these reasons brief combustion does not cause injury to the hand.

Materials:

• A container of water
• Liquid dish soap
• Flammable gas such as hydrogen or methane
• A lighter or long-reach lighter
• Gloves optional but recommended
• A large container or tray

Safety Warnings

This experiment must be conducted under adult supervision and preferably in a laboratory setting.

• The gases used are flammable and potentially explosive so extreme caution is required.
• The hand must be thoroughly wet otherwise there is a serious risk of severe burns.
• Protective eyewear is recommended.
• After the experiment hands must be washed thoroughly and the area ventilated.

Procedure

1. Fill a container with a small amount of water.
2. Dip your hand first into the water then into the liquid dish soap to ensure your hand is completely wet.
3. In a separate container prepare soap bubbles mixed with flammable gas such as methane or hydrogen.
4. Dip your hand into the soap bubbles to coat the surface of your hand with them.
5. Carefully ignite the bubbles on your hand using a long lighter or fire rod.
6. The flame will extinguish within a few seconds and your hand will remain unharmed.

Note: Never panic during the experiment and always use safety equipment such as goggles and gloves.
