00:00iBeliebers, it's Experiment Time!

00:04Okay, we'll also be experimenting with Teacher TikToker

00:08who has 2.4 million followers on TikTok.

00:10Wow, that's a lot!

00:12Kuya Chris, let's welcome Teacher Jess Placencia Esguerra!

00:17Hello, Teacher!

00:18Hello, iBeliebers!

00:21Welcome to iBelieve, it's good to have you here.

00:23Thank you for gracing us with your 2.4 million presence.

00:28A lot of people are watching us.

00:31So, Teacher, are you ready to experiment?

00:33I'm ready and excited, Kuya Chris!

00:36That's what I like!

00:37Okay, so as you can see, we have 4 cups here.

00:41One cup has a ping-pong ball, the other has a rock.

00:45I also have some sand in a beaker here.

00:49One is blue, the other is yellow.

00:51That's just the color.

00:52Now, what we'll do is you'll pour the sand on your objects.

00:57Go!

00:58Okay, then I'll tell you the challenge after.

01:01Beautiful!

01:02Yellow and blue!

01:03Okay, so your objects have been covered.

01:05The rock and the ping-pong ball.

01:06Now, your challenge is how you'll lift the object that's below

01:11to the top without touching the sand or moving the sand.

01:19Okay, that's your challenge.

01:21That's the rules, right?

01:22Yes.

01:23Okay, so, ready?

01:25Ready!

01:26Let's set, go!

01:30She's thinking of a strategy.

01:32Teacher has a strategy.

01:41Shaira, do you have a strategy?

01:43Here.

01:44Side by side.

01:52The rock doesn't want to move.

01:55Wow!

01:56That's great!

01:57That's fast!

01:58Wow!

01:59That's how it's done, Teacher!

02:01That's how it's done, Teacher!

02:02That's how it's done, Teacher!

02:03That's how it's done, Teacher!

02:05Do you believe that the rock will move?

02:07Right, Teacher?

02:08It should move, right?

02:09That's right!

02:10Yes!

02:11Okay, just try it.

02:12Go!

02:13Go!

02:14You can do it.

02:15Like that?

02:16What should I do?

02:17You'll see what Teacher will do.

02:18Teacher, what's the trick?

02:19Is there another way?

02:20Another motion?

02:21More shaking?

02:27There it is!

02:28There it is!

02:29It's moving!

02:30See?

02:32Yes, the rock is moving.

02:34I thought it won't move because it's heavy.

02:36Right?

02:37How did that happen?

02:38Maybe we can ask Teacher Jess

02:39what's the secret or the explanation

02:41why the ping pong ball is moving

02:44and the rock in the sand?

02:46Actually, the weight of the object doesn't matter.

02:49The secret is in the shaking of the sand.

02:52In the shaking?

02:53Yes!

02:54Oh, I see.

02:55While you're shaking the glass,

02:56there will be vibrations in the air molecules

02:59through the sand.

03:01Ah, I see, I see.

03:02Okay.

03:03And of course, because of this,

03:04there will be an upward force pushing the object up.

03:08Ah, okay, okay.

03:09It depends on the strength of the rock

03:11and the speed of the object moving.

03:14I see.

03:15So, earlier, I was doing it sideways.

03:17Yes.

03:18So, it's not moving up.

03:19It's not an upward force.

03:20Right.

03:21And it's a bit slow.

03:22It needs a bit of confidence.

03:24Like that.

03:25Like that.

03:26See?

03:27That's good.

03:28That's a good explanation.

03:29Wow!

03:30Thank you, Teacher!

03:31What do you guys think?

03:33Do you believe?

03:34I believe!
