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.
