Jeff thought about what he and his dad could do with the Chronivac. He hoped to find something that they could enjoy together, especially since they didn't spend time together very often. As Jeff scrolled aimlessly through the options on the Chronivac, an interesting idea popped into his head.
"Hey dad, I've got something in mind about what we can do with the Chronivac," Jeff said.
"What is it?" Mike asked.
"Actually, I'd like to keep it a surprise, but I think you will enjoy it. It won't be for too long, so we can try something else later if you have anything in mind," Jeff replied.
Mike chuckled. "Alright, whatever you say, I guess I'll find out soon enough."
"Don't peek at the screen and ruin the surprise."
"Okay, I won't. Do your best to surprise me." Mike turned away from the computer screen, leaving Jeff to key in the surprise changes. He could hear Jeff clicking and typing away at the computer, but he couldn't guess what Jeff was planning to do. After a while, Jeff called out, "Okay dad, I'm almost done and I'm going to start the changes soon. Are you ready?"
"I sure am. Let's do this."
"Here goes," Jeff said as he hit the confirmation button on the screen and began the transformation. But what changes did Jeff enter into the Chronivac?
