LEGO Engineering + Science

It’s always fun watching people push LEGO to the limits.  Here you can get a crash course in gear reduction and how to generate torque.  It’s interesting to see the differences in weights that can be lifted.  And it soon becomes apparent that the limitations aren’t in the gearing, or the motor, it’s the other materials which are failing.

Physics is Fun


Chaotic Pendulum aims to take the physics of gravity and show you how that force effects different connected masses.   It’s quite fun to play with, one of those endlessly fun websites that has some science attached to it, but is really just a useless game.  I spent some time making some pendulums.  The sharing tool doesn’t seem to work because no matter what I do, I always get a pendulum that starts out different then the one I made.  Oh well, randomize it anyway.

Giant Dominoes

Dominoes are fun to play with.  They might be a pain to set up, but you can use most anything to make them, and make them resemble almost anything, even play games with them. But this guy takes the whole thing to a new level.  There’s a science lesson in the above video.  What?!  Why would I go out of my way to teach you something?  Am I crazy?  No, I just think it’s cool, plus it’s only 2 minutes long, and the science you learn is pretty simple, so watch it.  Then feel free to watch something mindless.

I’m posting this under DIY simply because you can make your own dominoes and set them up and knock them down, but I don’t really know if you’ll be able to make that 100lb meter tall one, or the 5mm tall one either.
