0:00:00.000,0:00:04.000 Can you believe that Fixies are[br]Such itty-bitty creatures? 0:00:04.000,0:00:08.000 Even when they’re magnified[br]It’s hard to see their features. 0:00:08.000,0:00:12.000 They’re tiny, infinitesimal,[br]So small it makes you doubt. 0:00:12.000,0:00:20.000 But if you meet a Fixie, please,[br]Don’t let their secret out! 0:00:20.000,0:00:21.000 The Flashlight 0:00:21.000,0:00:22.000 Where is that thing? 0:00:22.000,0:00:24.000 Hi Tom Thomas! What are you looking for? 0:00:24.000,0:00:24.000 The flashlight. 0:00:24.000,0:00:25.000 Oh! Here it is! 0:00:25.000,0:00:26.000 Why do you need it? 0:00:26.000,0:00:27.000 Katya. I wanna talk with her. 0:00:27.000,0:00:28.000 Why not use the phone? 0:00:28.000,0:00:30.000 This thing's a flashlight, it's not a telephone. 0:00:30.000,0:00:31.000 No, you don’t understand. 0:00:31.000,0:00:33.000 Me and Katya came up with a secret code. 0:00:33.000,0:00:36.000 If I flash just once, then it means: "Hello there!” 0:00:36.000,0:00:39.000 Oh! And Katya has also said "Hello there" to you! 0:00:39.000,0:00:41.000 And two flashes, what's that? 0:00:41.000,0:00:42.000 Katya 's asking if everything's alright. 0:00:42.000,0:00:44.000 Now I’ll tell her that everything's good. 0:00:44.000,0:00:45.000 Oh, what’s wrong with this? 0:00:45.000,0:00:46.000 I think it's not working right. 0:00:46.000,0:00:48.000 I see, Nolik! But what's wrong? 0:00:48.000,0:00:51.000 Any flashlight is nothing more[br]than a battery and a light bulb, 0:00:51.000,0:00:54.000 connected by some wires[br]that are used to make a switch in between them. 0:00:54.000,0:00:56.000 To turn on a flashlight you flip on a switch. 0:00:56.000,0:01:01.000 That lets the electricity flow through the wires[br]from the battery to the bulb so it lights up. 0:01:01.000,0:01:04.000 And if it won't light up,[br]that means that the battery is dead, 0:01:04.000,0:01:07.000 the lightbulb is burned out, or the switch is broken. 0:01:07.000,0:01:10.000 And now, let’s put all this theory into practice! 0:01:10.000,0:01:13.000 I'm sorry but I don't have time right now, don't you get it? 0:01:13.000,0:01:15.000 If I don't signal back she'll think… 0:01:15.000,0:01:17.000 that I don't want to talk to her,[br]and that would just be terrible! 0:01:17.000,0:01:19.000 - Just don’t get all worked up![br]- We'll help you! 0:01:19.000,0:01:22.000 But first we need to get the mack-o…[br]the pack-o-mat and come right back! 0:01:22.000,0:01:22.000 See you! 0:01:22.000,0:01:23.000 Did you hear that?

It's not going to be that easy to repair it. 0:03:55.000,0:03:56.000 We’ll need a prosthesis. 0:03:56.000,0:03:59.000 The human body is built around a frame[br]of bones and joints. 0:03:59.000,0:04:02.000 And if you break one of the bones,[br]it will usually heal by itself. 0:04:02.000,0:04:05.000 The broken bone will grow back together[br]and you’ll be back to normal. 0:04:05.000,0:04:10.000 But sometimes bones or joints can break so badly[br]that it’s impossible for them to heal. 0:04:10.000,0:04:14.000 When this happens they have to be replaced[br]with an artificial part called a prosthesis. 0:04:14.000,0:04:17.000 A prosthesis can replace more than a bone or a joint, 0:04:17.000,0:04:19.000 it can be made to replace a whole arm or a leg! 0:04:19.000,0:04:20.000 And where are we going to get a prosthesis? 0:04:20.000,0:04:23.000 I'm positive we can get it from Professor Eugenius! 0:04:23.000,0:04:23.000 You’re right! 0:04:23.000,0:04:24.000 Help is on the way! 0:04:24.000,0:04:26.000 Hello!
