Hold on tight, we're going into a tunnel on an island! This is the Yerba Buena Tunnel, and the cars go through it on two floors, one on top of the other, like a sandwich! When the Bay Bridge opened, this was the biggest tunnel of its kind in the whole world.

It's so big that it holds ten lanes of cars, and it connects two parts of the Bay Bridge, like a hug in the middle! Inside, the sound changes. Everything goes hum, hum, hum.

Here's your job. When we go in, say Whoooa and listen to your voice echo. Who has the loudest echo in the car?
