Good episode? Give it some love!
We've gotten a lot of questions about bridges and tunnels: How do bridges stay up? How are tunnels built? How do they build bridges over water? How do they put tunnels underwater? To answer these questions we're staging a little friendly competition: bridges vs. tunnels! We'll find out how they're built, where they're found in nature, and what they may look like in the future. Plus: A visit from our friendly neighborhood robot.
