1 00:00:00,000 --> 00:00:10,000 Hi, I'm Bianca Baker, with more science news you can use. 2 00:00:10,000 --> 00:00:14,000 Why does a kernel of popcorn go from this to this? 3 00:00:14,000 --> 00:00:16,000 Hmm, what is that? 4 00:00:16,000 --> 00:00:22,000 Heat energy makes things expand and change from one form to another, like turning water into steam. 5 00:00:22,000 --> 00:00:25,000 Well, that's what happens to popcorn, too. 6 00:00:25,000 --> 00:00:31,000 Water goes past this hard shell into the middle of the kernel, which contains a little bit of water. 7 00:00:31,000 --> 00:00:36,000 As the water gets hot, it changes into steam and expands inside the kernel 8 00:00:36,000 --> 00:00:42,000 until there's no more room and the kernel explodes, turning into this. 9 00:00:42,000 --> 00:00:45,000 And it's ever so good. 10 00:00:45,000 --> 00:00:50,000 Well, until next time, I'm Bianca Baker, with more science news you can use. 11 00:00:50,000 --> 00:00:54,000 Thanks for watching!
