Jonathan felt the shrinkage slowly slowing down.
Just like that, the tingling sensations stopped. His shrinking had stopped, leaving him at approximately a foot tall; no higher than the size of a doll.
He stared down at the floor. His emptied clothes spread haphazardly over the floor. His miniscule penis dangles, as he realized he was naked. After all, this was for science, and modesty was sort of silly when you were trying to record physical changes.
He had failed to take into account that the shrinking formula had no effect on his clothes.
"The formula worked. I'm now no higher than a foot tall. I'm now a small man in the history of science." He said.
He wondered if the formula would even wear off.
He felt like living as a doll sized man.
