For those curious what happened these boys are incredibly smart. They used a wood that was able to flex for their main structure and constructed it in a way that the frequency of the vibrations in the material was synonyms with the frequency of the quaking. Since they were in sync there was no visible shaking in the building and this is a real technique engineers use when designing skyscrapers.

Engineering student here! This is called modal frequency analysis. It's like pushing a swing at the right moment, causing it to go higher and higher. The exact opposite happened here: the external force wave and the resonant wave of the building canceled each other out. That's also how noise canceling headphones work.
Basically, vibrations can be dangerous if they're at the right frequency. In fact, vibrations can cause the screws on an airplane can unscrew themselves if you're not careful! This same phenomenon is also how you can break glass with sound

This is most likely a high-school Engineering class. I had a similar lesson learning about how skyscrapers are built! The steel structure has to be suspended on shock absorbers like a car to absorb earthquake damage. Each of us had to build our own little skyscraper using nothing but popsicle sticks and glue. Fun stuff!

Is this what a well funded school is like? seems fun
