Place a candle in a container -- here, a plastic box. Surround the candle with water, but be sure that the wick is in the air. Light the candle.
Cover the candle with a glass or a jar that you can see through. Tilt the glass a little bit so that the water can go up into it.
As the candle burns, the water rises in the jar. The water rises to replace the used-up oxygen. The flame goes out when it has used up all the oxygen in the jar. This happens very fast. It's a little hard to see in the pictures how much the water has risen, but it comes up to the square part of the jar, and it's much higher than the level of the water in the plastic box.
Try this yourself (with a grownup to help) and you will see how the water rises very quickly and then the candle goes out. It makes a little sucking sound when the water rises.August 2006 September 2006 October 2006 November 2006 December 2006 January 2007 February 2007 March 2007 April 2007 May 2007 June 2007 July 2007 August 2007 September 2007 October 2007 November 2007 December 2007 January 2008 February 2008 March 2008 April 2008 May 2008 June 2008 July 2008 August 2008 September 2008 October 2008 November 2008 December 2008 January 2009 February 2009 March 2009 April 2009 May 2009 June 2009 July 2009 August 2009 September 2009 October 2009 November 2009 December 2009 January 2010 February 2010 March 2010 April 2010 May 2010 June 2010 September 2010 October 2010 November 2010 February 2011 May 2011 September 2011 March 2012 April 2012 May 2012
