A Candle Underwater

Question/Purpose: What will happen when we put a lit up tealight candle on top of a bowl with water?


Materials: 1 tealight candle,1 lighter a medium glass bowl,a clear glass,water, ans a adult.


Hypothesis: what i thought will happen is that ashes will go into the water because how fire creates ashes.


Steps:
  1. Firstly grab your medium glass bowl and fill it with water halfway.
  2. Then take your tealight candle and make sure you have an adult to light up your candle because it’s really dangerous.
  3. After that then take your lit up candle and gently place it on the water in the center.
  4. Afterwards when the candle is on top of the water then grab your glass cup and push the candle down
  5. till it reaches the bottom of the bowl.
  6. And watch what happens?


Results: what i saw was that how the air in the cup pushes all the water out and air bubbles came out.
What i felt is that the flame was running out
of air and it couldn’t stayed lit so that why it went weaker and weaker. What i smelt was the flame inside the cup
was steamy up and then it started to get foggy and more foggy. I could hear how the water is filling up inside of
the glass cup and that the
candle is already going out.
I see that the flame is still going and that the oxygen inside the cup is losing air.


Conclusion: what i learnt is that the air in the cup pushes the water out and maybe approximately about
7 seconds it goes out and water starts rising up into the cup.
