1 00:00:00,000 --> 00:00:08,000 Hi, I'm Wesley Benson with more science news you can use. 2 00:00:08,000 --> 00:00:12,000 Ow! That doorknob just zapped me. Why? 3 00:00:12,000 --> 00:00:16,000 You got zapped because of static electricity. Let's figure it out. 4 00:00:16,000 --> 00:00:19,000 See, all matter is composed of atoms. 5 00:00:19,000 --> 00:00:24,000 Atoms usually have an equal number of positive and negative charges, protons and electrons. 6 00:00:24,000 --> 00:00:30,000 Atoms can gain or lose electrons when two different materials, like you and the doorknob, contact each other. 7 00:00:30,000 --> 00:00:35,000 As you walk across the carpet, you develop a negative charge as electrons move from the carpet to you. 8 00:00:35,000 --> 00:00:38,000 This charge is known as static electricity. 9 00:00:38,000 --> 00:00:43,000 When you went to open the door, the electrons jumped from you to the doorknob. 10 00:00:43,000 --> 00:00:46,000 That caused an electrical spark. Shocking, isn't it? 11 00:00:46,000 --> 00:00:49,000 Is there some way I can avoid getting shocked? 12 00:00:49,000 --> 00:00:52,000 Easy. Make your brother open the door for you. 13 00:00:52,000 --> 00:00:58,000 Until next time, I'm Wesley Benson with more science news you can use.
