Jon opened his closet door and laid his eyes on the new device that existed there. Basically, it looked like a giant glass tube connected to complicated machine made up of metal and wires. Jon presumed that all he had to do was step into the tube through its opening to use it. There seemed to be enough room for both Jon and Karyn, and maybe a little more for one more person. But he only intended to use it for himself and Karyn.
They stepped inside the tube and waited. "Now what? How does it work?" Karyn asked.
"PLEASE INPUT."
"Who said that?" Karyn asked.
"I think it's the machine," Jon said. "It must be voice-activated. Cool."
"PLEASE INPUT."
"It's getting impatient, Jon."
"Well? What time do you want to travel to?" he asked Karyn.
