So, I'm working on a research paper, and my teacher told us our topic can be "Physics of [anything you could possibly think of]." So, I chose Lego building, not picturing that pretty much every site I look up is about how to simulate physics theories with Lego bricks. I was wondering if you guys know anything about the physics of Lego I can borrow, and it would be very nice if I could get sources from it (although most of the sites will probably get blocked). Thank you.
