He relit the candle with a converging lense or magnifying glass. If the light is directed on the wick of the candle it will relight.

The shape and angle of candle will effect how long a candle burns because when a candles reaches the middle of glass jar candle, the lack of oxygen to feed the fire causes it to go out.
Incomplete combustion causes carbon dioxide to leave carbon behind on the glass

simple. place a piece of paper that is a little larger than the circumference of the glass on top of the glass. The next step is to flip it over completely with a good speed. not too fast though... after this you will observe a glass of water that is completely upside-down and it won't be spilling if you used the right paper. *this will be most effective if the glass of water is completely full*

The burning flame on a candle needs three things to continue burning: 1) fuel, which it gets from the wick 2) heat, which comes from lighting the candle 3) oxygen Without any one or more of these three things, the candle will no longer continue to burn. In the case where a candle is covered with a glass, the candle quickly uses up the oxygen inside the glass. once all of the oxygen is gone, the flame will burn out.
The Eureka beaker was created in 1955 by Corning Glass Works in collaboration with Dr. Donald F. Kubly. It was designed to measure liquids accurately by utilizing a narrow neck and conical shape to prevent liquid from spilling.
