A Moment of Science
No sooner are they blown out, then they re-light and can be blown out again. How can a candle light itself?
Everyone wants to know what to in case of a fire. Will cold water work better?
You took a stack of paper and burnt it. What happened to the papers when you lit them up?
How does fire pass from one burning stick to another unlit stick?
You've probably seen things decay before. How does the process work?
What appears to be a dark cloud or haze to our eyes is actually made of millions of tiny particles–in this case, not of water, but of burnt matter. There are two kinds of smoke detectors: ionization alarms and photoelectric alarms.
You can think of a flame as being like a kind of tent. Heat melts the candle’s waxy fuel, and turns it into a gas. This fuel gas floats away from the wick to fill the inside of the flame’s tent.
