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!
