In this video, I demonstrate a science experiment where a candle stays lit underwater by using a cup filled with air. I break ...

The candle warms the air inside the glass, causing higher pressure. After the candle goes out (due to the oxygen being used) the air begins to cool. This cooling air creates lower pressure, creating a ...

A candle appears to be underwater by superimposing the transmitted light from the beaker with the reflected light from a candle. A pane of glass between the candle and the beaker acts as both the ...

You can join Captain Zoom and her scientist friends Amy and Mark on Let's Find Out. Step aboard the spaceship Curiosity for some exciting experiments, curious kids and trips to faraway places. Watch ...

Once the glass is placed over the candle, the air is heated and it expands. The resulting pressure forces some air out of the glass (the bubbles). When the oxygen is consumed, the flame goes out. Then ...

1. Ask the adult you are working with to light the candle. 2. Watch the candle flame start out small and get bigger. Notice how some of the wax near the wick melts. 3. As the flame burns, the wax from ...
