Jon decided to start off small with his testing, just incase something went wrong.
He concentrated on his right arm and stretched it out a bit. Then he tried it with his left. He decided to see how far they could actually go. He continued to stretch them out. Surprisingly it didn't hurt him at all. They just kept growing out from sholders.
He set them easily on the ground. Soon he had two piles of snake like flesh growing higher and higher. He laughed. This was so cool. He shook his arms. The piles quivered.
When his arm piles had grown up to his knees, Jon decided that they could grow infinitely (or at least that is what it seemed) without hurting him.
He picked up his arms and traversed them throughout the bathroom, looping them through anything he saw (towel hangers, door knob, shower head, pipes under the sink) In moments the bathroom looked like a living spider web. "Ok, lets test this web out" he said.
Jon Grabbed onto the edge of the window at one end of the room and top of the door at the other side of the room. He picked up his feet. SUCCESS! His abnormally long arms could now support his entire weight.
