The test subject that the scientist had gotten was a young, thirteen year old boy. The scientist had gone off for just a minute to grab a snack when his thirteen year old nephew came in. The young boy saw the machine and was intrigued by it. He walked over to it.
"What does this do?" he asked. He pressed a few random buttons. The young boy was always playing with his uncle's "toys". Sometimes he would accidentally break them. Or just break them on purpose. He started playing with all the buttons until smoke started to rise from the machine.
"Whoops. I broke it." he laughed. At this point the scientist came in and started in surprise.
"Ed! What did you do!"
"Oh, sorry Uncle Ray. I was just messing around." Ed grinned. Before the scientist yell at his nephew, the machine came to life. It's gears spun wildly and it's engine roared in fury. Steam shot out of pipes and the green light bulbs in the front turned angry red. Ed jumped back from the controls and both he and his uncle stared at the machine.
Wires popped out and from the opening, a chain came out and wrapped around Ed's waist.
"Uncle Ray! Help!" he called out as he was pulled into the machine. Ray took a step forward, but stopped. He did need test subject. Why not his annoying nephew?
