The satchel (Part 1)

Adam had been pretty excited for his summer internship at a research lab. He had heard about some of the inventions they had been working on and couldn’t wait to see them first hand. However, he was soon disappointed when most of his duties involved getting coffee or bringing packages to other labs. He didn’t get to see anything in action. That all changed one day when he was given a small leather satchel with delivery instruction. He thought it was just another courier duty, but he had no idea what was inside. No one at the lab told Adam he would be a test subject of their latest invention. They monitored his location, and when Adam was close enough to another intern from another lab carrying a similar satchel, both labs activated their devices. Adam instantly noticed the change: He had switched bodies with the other intern!
