1 00:00:14,580 --> 00:00:17,179 What is a thrust? 2 00:00:17,620 --> 00:00:21,579 A thrust is a contact caused by water and iron. 3 00:00:22,179 --> 00:00:27,839 A thrust is a pressure in air and water up. 4 00:00:28,480 --> 00:00:34,060 A thrust is an opposite force to gravity. 5 00:00:34,939 --> 00:00:36,700 Extra information! 6 00:00:37,700 --> 00:00:43,659 The mass and the volume of an object influence the amount of a thrust. 7 00:00:44,579 --> 00:00:51,579 An object with a small mass and a big volume has a lot of upcrust. 8 00:00:51,579 --> 00:00:57,579 This is why a fair falls slow and floats. 9 00:00:57,579 --> 00:01:03,579 An object with a large mass and a small volume has less upcrust. 10 00:01:03,579 --> 00:01:09,579 This is why a coin falls very fast and skims in water. 11 00:01:09,579 --> 00:01:12,579 Experiment! 12 00:01:14,579 --> 00:01:24,579 We put the little paper boats with each one a bigger bowl of plastic canes, sang first 13 00:01:24,579 --> 00:01:31,200 the little boat that had the medium bowl, sang the second and the one with the smallest 14 00:01:31,200 --> 00:01:49,459 bowl, sang later ended up in the lost city of Atlantic City.
