Once there was a boy who wanted to build a rocket, but he doesn't have enough material for It the metal was too heavy, he tried to find another material but they were all too heavy, and it just wouldn't take off, so the boy found Copper . It was lighter than most of the metals he used, so he put that on the rocket and then he added engines to the bottom of the rocket ,and he attached wings to it . He turned on the rocket and It flew in the air like a bird and it blew up with fireworks
