As the elevator continued it's slow ascent, Jess shook her head in discomfort.
"Dad. My ears."
"What's going on?" Nima asked.
Gerry noticed a sign on the elevator wall.
"The rotunda and underwater tunnels are pressurized, and it explains what we need to do to make sure the pressure doesn't cause any discomfort." He said. "We should pinch our nose and hold our breath to allow the pressure inside our ears to equalize."
Nima, Gerry, and Jess followed the procedure. Yoder shook is head at the sight and just leaned against the elevator wall.
"Giddy?" Gerry asked, noticing the warning signs posted on the wall.
"They're talking about nitrogen narcosis." Jess explained. "It's a risk of breathing pressurized air."
"What makes you the expert?" Gerry asked.
"I, ah...saw it in a moving picture." Jess said. She looked out the window of the elevator.
"Woah...is that where we're going?" Jess asked, noticing the rotunda.
"I think so." Gerry said. "My God. I wasn't expecting any of this."
"This is so neat!" Jess said.
The elevator soon halted and the doors opened.
The group stepped out into the underwater tunnel.
