Lighting Your Hands
Aim: To listen to the teachers instructions while using safe practice in the science lab.
Hypothesis: There will be flames coming from your hands.
Equipment:
Bunsen burner tube
Gas
Detergent
Water
Method:
- Put some water into a container and squirt in some detergent.
- Connect the gas hose to the taps and make gas bubbles in the water.
- Rub cold water on your hands, wrist and up to your eyebrows.
- Scoop up the bubbles in the container into the palm of your cupped hands.
- Stand with your hands reaching out in front of you, with your palms and bubble facing up.
- DO NOT TRY THIS AT HOME.
Safety: If you want to stop the fire you can open your palms and drop the fire to the floor.
Results: The hands of the person burst into flames without burning their hands.
Discussion: The gas in the bubbles burned.
Conclusion: So my conclusion is that when the detergent came in contact with the bubbles, the bubbles turned into flames. When you separate your hands the flames degenerate into the air.
