Waaaoooosh! 😮 🔥 A jar was coated with some sort of volatile organic compound before the resulting fumes within the bottle were quickly set alight. The flames reveal the gas's fluid-like behavior as it's eaten up by the fire and its upper surface contracts. A mournful wail also wooshes from the glass. Don't try this at home: if the timing is off or the wrong amount of liquid is used a violent combustion will explode the bottle, shattering sharp shards of glass everywhere. 📷 via imgur | Science
