Aired (March 10, 2024): There are many ways to recycle your plastic bottles, one is to create a water fountain, where a toy from discarded bottles is made into a device with infinitely flowing water.

00:05 Guys, what can we do with empty mineral water bottles?

00:09 Of course, we can recycle them!

00:11 We will make a looping water bottle fountain.

00:15 [music]

00:18 Three water bottles.

00:19 First, we will make two holes here.

00:22 Two.

00:23 Two holes.

00:24 Okay.

00:25 Then, we will put it in the second water bottle with a hole.

00:29 And in the third water bottle, we will put it on top.

00:33 Okay.

00:34 Then, we will stick them using these straws.

00:38 And then, here it is.

00:40 Magic!

00:41 Wow!

00:42 Magic!

00:43 Okay, okay, okay.

00:44 This is our water bottle.

00:47 Ate Shai, what is that?

00:48 What is this, Chris?

00:50 It looks like...

00:51 The wheel.

00:52 The wheel.

00:53 Yes, it does.

00:54 Okay, let's put it here.

00:55 We will adjust it later.

00:57 It depends on the water level.

00:58 So now, we have colored water so we can see how the water flows.

01:05 So, thank you.

01:07 Very well sealed.

01:10 And then...

01:12 It's color is so beautiful.

01:13 When it's full at the bottom...

01:15 There it is!

01:16 There, it's floating!

01:17 We need to...

01:18 It's floating!

01:19 Yes, it's going to push the water to the next opening.

01:22 We need to tilt it like that so the water will flow first because there's no push yet.

01:27 So, we've moved a lot of things from this bottle to this bottle.

01:32 Now...

01:33 Okay.

01:35 There!

01:39 There!

01:42 We now have a looping fountain toy.

01:45 What can you say?

01:46 I believe!

01:49 The experiment we did is a variation of Heron's Fountain.

01:54 It's an invention of a first century Greek mathematician and engineer named Hero of Alexandria.

02:01 When we poured water, the bottle that was lying on the bottom was the first to fill up.

02:07 When we added water to the top bottle, the water fell more on the bottom bottle or the one lying on the table.

02:17 Earlier, it was just air but now, it has water.

02:22 That's why the air was displaced from the bottom bottle to the one lying on the table.

02:30 The air pressure is strong there so the water will push to the top bottle.

02:38 The reason is so the water will go down to the bottom bottle and the cycle will repeat.

02:45 It's fun to watch this water loop but it will stop eventually

02:50 because this is not a non-stop or perpetual motion machine.

02:54 It is impossible because it does not follow the laws of physics.
