00:00In an exhibit held in Pangasinan, what should have been a fun occasion to learn,
00:13was brought back to life in fear when a woman suddenly let go of her hand.
00:21We all screamed because it was like she was about to explode.
00:30This October 4, the first academic exhibit of students from grade 7 to grade 12 was held in this school.
00:38In the event, each had their own booth.
00:43Some of the exhibits were the English Booth, Filipino Booth and Math Booth.
00:48One of the judges was CJ.
00:51One of the judges was CJ.
00:54I was just an accidental judge that day.
00:58They had a Science, Math, English, and Filipino Exhibit in the school,
01:04and they didn't have a judge.
01:06So, Ma'am Queen asked her friends if we were doing anything.
01:12I said, no.
01:14She said, I'll just get you judges.
01:17Because she's a friend of Teacher Queenie, an advisor in education,
01:20and a former student here,
01:22CJ quickly agreed to be a judge.
01:25She also enjoyed the booths of the students.
01:29What we expect is that they have a booth.
01:32Every booth, they prepare a game.
01:35In the Filipino Booth, it's a color game.
01:37In Math, you have to remember the numbers.
01:40In English, they showed us books.
01:44But of all the booths that CJ went through, this was the most memorable.
01:49The Science Booth.
01:51The experiments are all about science.
01:55The fun experiment is supposed to be like,
01:58the fear of her and the other students disappeared.
02:00When she suddenly raised her hand.
02:05This experiment is called, Fiery Hand.
02:08The goal of the experiment is to light a fire on the board.
02:12But it should be small and it should disappear quickly.
02:15I watched it with my friend.
02:17He was the first one to join.
02:19The fire was small.
02:20That's why she panicked.
02:22It was a big and long fire that she made.
02:25I felt that it was hot.
02:27Because the fire was long gone.
02:29But the first mistake,
02:31CJ was told to put her hand back on the board.
02:35To make a bigger fire.
02:37My first instinct was,
02:39the fire doesn't want to go away.
02:40I put it back on the board.
02:42Which is wrong because the source of the beauty is on the board.
02:46The beauty.
02:47The fire.
02:48That's why she panicked.
02:50There's water actually.
02:52But the water is at the bottom.
02:55Oh no!
02:56Experiment gone wrong?
02:59What's in that bowl?
03:01To make the Fiery Hand experiment,
03:03you just need three things.
03:05Water.
03:06Liquid soap.
03:07And butane gas.
03:09There's water and soap in the bowl.
03:11Just soak the butane gas until it evaporates.
03:14This bubble is what CJ will put her hand on the board.
03:18I didn't understand the instruction.
03:20It should be just a bubble.
03:22What I did was,
03:24I soaked my hand.
03:25And there's water.
03:27That's why when they put my hand on the board,
03:29it caught fire.
03:31And it was gone for a long time.
03:33The fire that evaporated in this experiment,
03:36is because of the combustible material used.
03:39Our butane gas is
03:41a kind of hydrocarbon.
03:45Because it's light and small,
03:47it's in a gaseous state.
03:49And it has the ability to trap
03:51or stick to the bubble.
03:53Now, our butane gas
03:55is called combustible materials.
03:57Or flammable materials.
03:59They're the things that can easily burn.
04:02When she put it in a bigger basin
04:04or in a bigger basin,
04:06there's more concentration of butane molecules there.
04:09And there was a heat transfer.
04:13I thought,
04:14Oh no, I made a mistake.
04:16My face might get burned.
04:18Even though the fire was big,
04:19it didn't cause CJ to get injured.
04:22But why didn't the skin get burned
04:24when she was doing this experiment?
04:27It's because of the surface tension
04:29in our dishwashing liquid.
04:31So, that dishwashing liquid
04:33has the ability to create
04:36or open a film.
04:38And that film is the reason
04:40why our skin doesn't get burned.
04:42Because when it's ignited,
04:45or that film is ignited,
04:47there will be a cooling effect
04:49around it.
04:51According to the expert,
04:52it also quickly goes out of fire
04:54because of the oxygen reaction.
04:57That fire goes out
04:59when it's exhausted
05:01or when the so-called butane gas is gone.
05:03Because it's called
05:05a vaporization process.
05:07So, if the butane liquid
05:09or the butane vapor is gone,
05:11if there's a combustion reaction,
05:13the fire will also go out.
05:15According to the expert,
05:17in order to avoid a possible fire,
05:19it's important to be careful
05:21when doing any experiment
05:23that has a related fire.
05:25It's important to do it outdoors
05:27so that there's not too much equipment
05:28that can catch fire
05:29and to avoid spreading
05:31the open flame quickly.
05:33Personal protective equipment
05:35can also be used
05:37like hair ties,
05:39glasses or goggles,
05:41lab gown or apron,
05:43and shoes.
05:45Prepare a fire extinguisher
05:47and above all,
05:49do an experiment with an experienced
05:51and experienced expert.
05:53CJ's hands are shaking.
05:55She wants to give the kids
05:57a higher grade
05:59because of their science booth.
06:01We gave them higher grades.
06:03I think they won
06:05in science.
06:07And today,
06:09she's ready to do the firing hand experiment
06:11in the right way.
06:23The difference is
06:25that there's only a little fire.
06:27So, it's not that hot.
06:29It's more enjoyable now.
06:31Sorry, it's really hot
06:33and it's fun to study.
06:35But you need to be careful
06:37to always avoid danger.
06:39Aha!
06:41Aha!
