Science Question for School

Postby FendeR` on Thu May 19, 2005 11:38 am

This is a really simple experiment, but I can't think of exactly how it works. Here it is:

You have 2 candles, and you light them both. You then hold them like handle bars, but you put one above the other (flames above eachother, but not touching at all). Then you blow out the top candle, and without touching the flame on the bottom candle, the top candle relights.

I assume it's either oxygen or carbon dioxide or something, but I'm just looking for clarification so I don't look like a dumbass. And don't laugh at me, it's only 7th grade science :cry:

The heat from the bottom flame rises and re-heats the wick (the thing that you light on a candle) of the top candle and it re-ignights

Yeah anyway I figured it out. I dobut anyone's interested, but this is how it's "supposed" to be. You actually blow out the bottom one, and then get the smoke that comes up (actually wax vapor) to rise into the upper flame. The fire then shoots down the smoke trail faster than you can see and relights the bottom candle.

:cry: My teacher told me I should blow out the bottom one today, when my instruction sheet said in clear English that the top candle should be blown out. Whatever.
