00:05 Guys, we've done a lot of things with drawing here in iBelieve, right?
00:09 But I'm telling you, the style we're going to do today is very unique.
00:14 Very unique? Why, Kuya?
00:17 Because we're going to draw on a rotating surface.
00:20 [music]
00:23 This is just steel, and we have a spinner that we glued to a board.
00:29 This is just a whiteboard.
00:32 You can use a whiteboard or cardboard.
00:34 The surface is slippery, so you can erase it.
00:37 And then we have a whiteboard marker.
00:38 So, Ate Shira, can you spin it in any direction?
00:41 Okay, one, two, three.
00:43 [music]
00:45 Look.
00:46 Oh, wow.
00:47 [music]
00:48 Let's do the effect.
00:50 [music]
00:51 What effect should I do?
00:54 This is perfect. You're good, guys.
00:56 Spin it again.
00:59 Ready, get set, go.
01:01 Wow!
01:03 Perfect circle.
01:04 Perfect.
01:04 Perfect circle.
01:07 Now, let's add a little design.
01:10 [music]
01:14 Okay, let's try.
01:17 One, two, three, spin.
01:20 Wow!
01:23 [music]
01:25 Persistence of vision.
01:26 This is also the principle behind moving drawings.
01:31 Where each page has a picture,
01:33 and when the pictures are shown one after the other,
01:36 it seems like it's moving.
01:37 But in this experiment,
01:39 the equivalent of each page is the segment,
01:42 or the part of the rotating disc,
01:45 or the rotating circle.
01:47 The movement in this experiment is spinning.
01:51 In our brain,
01:52 the picture has an afterimage
01:54 of the first part of the rotating disc
01:57 that our eyes are pointing at.
01:59 So when we see the next part,
02:03 there's an illusion.
02:04 We think it's just one continuous movement.
02:08 In our experiment,
02:09 the drawings that are separated
02:11 from the circular cardboard
02:13 are not really moving.
02:15 But when we spin it quickly,
02:17 the persistence of vision effect happened.
02:20 It's like the drawings are alive and moving,
02:22 or the drawings are dancing.
02:25 I believe!
02:26 iBelievers!
02:28 Do you know where the old ink or ink came from?
02:32 From oil!
02:34 Oil was burned before,
02:36 or oil until it turned black,
02:38 and there's a residue of foam.
02:40 And it's mixed with glue or gum to harden,
02:43 and of course,
02:44 when you use it,
02:46 you'll get wet.
02:47 Oh!
02:47 There, iBelievers,
02:49 you know where the ink came from.
02:51 I love Nadis!
02:52 I love Nadis!
02:53 I love Nadis!
02:54 [END]
