Tom felt the top page, ran around it with his fingers, and then carefully slid his hand beneath the last page, found the button on the desk top, and held it down while he removed the manuscript.

He lifted. It gave him the screaming willies, and instinctively, Tom pressed hard on the button.

His elevator changed direction. It gave him the effect of being hit on the head with a sand bag. It was now accelerating upward at a violent rate.

He let the button up slowly. The feeling ceased as he reached a pressure about even to the weight of the manuscript; stopping all at once. He compensated by dropping an equal number of blank pages from the desk on the button and took the manuscript to his easy chair to read.

It was one of those things. It couldn't be denied. He was going to be forced into presenting this paper before the American Physical Society, using his full name and all of his degrees and the works. The physicist and his little tungsten box would see to it that he remained an engineer until the paper was presented, fully and completely. The physicist didn't have all the answers, of course, but he had solved some of the basic problems.

He finished the manuscript, and then found a letter. It said:

Dear Galileo:

The phenomenon of losing fifty pounds is the result of an antigravity field which I discovered from your data on the good old poltergeist. The trouble with the thing is simply this:

In order to make the thing function, it takes something like three tons of equipment to make the object within the field lose its fifty pounds.

I, as a physicist, do not care about the practicality of the device. I have made it work. You, as an engineer, will appreciate the possibilities behind the perfection of this device. I offer you the chance to start your Poltergeist Moving Company, providing, of course, that you can make something of this effect.
