A mixture of alcohol vapor and air can produce a whoosh sound when ignited. This demonstration is often referred to as the "whoosh bottle" experiment.

Here's how you can perform the whoosh bottle experiment safely:

Safety precautions: Perform the experiment in a well-ventilated area, preferably outdoors, away from flammable materials. Ensure that there are no open flames nearby, and have a fire extinguisher or a bucket of water readily available as a safety precaution. Wear safety goggles and protective clothing.

Equipment and setup: You'll need a large glass or plastic bottle with a narrow neck, such as a carboy or jug. Ensure that the bottle is clean and free from any flammable residues. The size of the bottle will depend on the amount of alcohol vapor you want to generate. A bottle with a capacity of several liters should work well.

Alcohol preparation: Prepare a mixture of alcohol and air by pouring approximately 70% pure isopropyl alcohol (rubbing alcohol) into the bottle. The alcohol vapor will mix with the surrounding air.

Evaporation: Swirl the bottle gently to increase the surface area of the alcohol exposed to air, promoting faster evaporation. Allow the alcohol to vaporize for a few seconds, giving it time to mix with the air in the bottle.

Ignition: Carefully ignite the alcohol vapor by using a long match or a long-handled lighter. Extend your arm and light the vapor by holding the flame near the mouth of the bottle. Be cautious and stand back to ensure your safety.

Observe and listen: As the alcohol vapor ignites, you will hear a loud whoosh sound and see a brief flame that shoots out of the bottle. The flame should extinguish quickly, leaving behind a plume of smoke.

Remember, it is crucial to exercise caution and prioritize safety when performing any experiments involving flammable materials and fire.
