'A conniving salesman named Giffen sells a glue that will stick to anything, but stops working after four hours. After getting many innocent townspeople to buy it, he leaves town in his truck before they can track him down for cheating them, then meets a man who has invented a box that can make people fly into the sky. Attempting to try it for himself leads to the biggest mistake of his life.' (https://en.wikipedia.org/wiki/Unreal_(short_story_collection)
