Tim has a chance to invest in Vapoorizer, the latest harebrained venture by his friend Nick . While the details are sketchy, Nick claims it's a chemical that can make any substance disappear. Not expecting Vapoorizer to amount to much, Tim declines -- only to watch the product become enormously profitable.
