Soon all the cavorite is either face down or has shot into space. Normal gravity returns. We land, dirty and bruised, amid the ruins of the house.

Everything around us is flattened. For miles around, every window is broken and every fence blown over. Uncle says it could have been much, much worse. He does not worry about loss of life, it's just science to him.

This stuff is miraculous! Forget the damage, should we think of how we can use it? Or do something else?
