Candle

  • 0:01 - 0:02
    Hello everyone!
  • 0:02 - 0:03
    I am Yuhish Maharjan
  • 0:03 - 0:05
    I am 14 years old
  • 0:05 - 0:06
    I am from Nepal
  • 0:06 - 0:08
    I live in Lalitpur, Nepal
  • 0:08 - 0:09
    I am in grade 9
  • 0:09 - 0:13
    My school's name is West Wing secondary school
  • 0:13 - 0:16
    Today I am here to show you the experiment
  • 0:16 - 0:18
    named underwater candle experiment
  • 0:18 - 0:22
    In this experiment we can know how the
  • 0:22 - 0:24
    candle burns inside the water and we can
  • 0:24 - 0:27
    see the wick of the burning candle
  • 0:28 - 0:29
    Hello everyone!
  • 0:29 - 0:31
    Materials required for the experiment are
  • 0:31 - 0:32
    Lighter
  • 0:34 - 0:36
    Candle
  • 0:37 - 0:41
    Measuring tape
  • 0:42 - 0:44
    A glass of water
  • 0:47 - 0:49
    Small pin
  • 0:51 - 0:53
    Transparent bowl
  • 0:59 - 1:02
    First, stick the candle into the bowl
  • 1:02 - 1:04
    Do this by lighting the candle and
  • 1:04 - 1:06
    allowing the candle to drip into the bowl
  • 1:07 - 1:10
    Make sure that enough wax drip into the bowl
  • 1:10 - 1:11
    to make the candle stick
  • 1:15 - 1:17
    Once there is enough melted
  • 1:17 - 1:18
    candle wax in the bowl
  • 1:18 - 1:20
    stick the candle into it
  • 1:23 - 1:26
    Wait to dry for about five minutes
  • 1:28 - 1:30
    Next, pour water into the bowl
  • 1:30 - 1:32
    until just the top of the candle
  • 1:32 - 1:34
    You don't want the candle to be
  • 1:34 - 1:37
    fully submerged in the water at this point
  • 1:45 - 1:48
    After that, light the candle
  • 1:48 - 1:51
    My lighter is not working so I will be
  • 1:51 - 1:53
    using another candle to light this candle
  • 2:01 - 2:04
    Now, slowly watch as the candle burns
  • 2:05 - 2:07
    It will continue to burn even when the
  • 2:07 - 2:09
    wick is below water level
  • 2:17 - 2:19
    Sometimes, the candle dims and goes out
  • 2:19 - 2:21
    just before the candle dies
  • 2:21 - 2:24
    the water level rises almost
  • 2:24 - 2:26
    one 10th of the pitcher
  • 2:26 - 2:28
    No air bubbles have I seen
  • 2:28 - 2:30
    The water level stays up for
  • 2:30 - 2:32
    many few minutes more
  • 2:32 - 2:34
    We measure how far the candle
  • 2:34 - 2:35
    has burned down beneath
  • 2:35 - 2:36
    the surface of the water
  • 2:36 - 2:39
    Mine went down about 1,5 centimeters
  • 2:39 - 2:41
    That's all, this was my experiment
  • 2:44 - 2:46
    The conclusion of this experiment
  • 2:46 - 2:47
    goes like this
  • 2:47 - 2:50
    We can see that as the candle burns
  • 2:50 - 2:52
    A part of the wax surrounding the wick
  • 2:52 - 2:53
    does not melt
  • 2:53 - 2:55
    leaving a well of protection around the wick
  • 2:56 - 2:58
    This allows the candle to continue burning
  • 2:58 - 3:00
    even though the flame is already
  • 3:00 - 3:02
    lower than the water
  • 3:02 - 3:04
    Basically, the cool water surrounding
  • 3:04 - 3:06
    the candle is absorbing the heat
  • 3:06 - 3:07
    from the flame
  • 3:07 - 3:09
    This allows the wax to stay solid
  • 3:09 - 3:11
    instead of melting and dripping
  • 3:11 - 3:13
    on its sides like it normally does
  • 3:13 - 3:15
    and that is how the candle can
  • 3:15 - 3:16
    keep burning
  • 3:16 - 3:17
    That is all for my experiment!
  • 3:17 - 3:18
    Thank you!
