1 00:00:22,449 --> 00:00:30,530 In the practice two, they attract, but in the practice three, they don't. 2 00:00:30,530 --> 00:00:34,770 They are not attracting each other, so we don't see the lines, yes? In between them. 3 00:00:34,770 --> 00:00:39,329 Yes, but this one, these are not lines. 4 00:00:39,329 --> 00:00:40,210 What, Javi? 5 00:00:40,210 --> 00:00:41,969 This one. 6 00:00:41,969 --> 00:00:45,570 Ah, okay. So they repel each other. 7 00:00:45,570 --> 00:00:46,070 Yes. 8 00:00:46,070 --> 00:00:49,289 They repel each other. Fantastic.
