What we're gonna do is - This is what i call the Swagger Stick that Steve sent me it's an index so you can set up the dominoes and Set them up the same every time We've got a ruler for motion Analysis here and we can change out the type of material that we're knocking the domino's over on. We've got different kinds of felts and things like that, we've got this dry erase board, we've got some metal down here... We're gonna look at all the variables TRENT>> Here we go DESTIN>> And we're going in It's pivoting about.. That's - what - exactly what it's doing Oh dude i just had the moment where it all clicks. It's - it's rotating about the center of gravity It's exactly what's happening.
As it's falling you have translation and rotation and so that front edge is a pivot point But if there's not enough friction.. are you seeing it? Yeah, it's - it's trying to rotate about its center of gravity If there's not enough friction. Let's put the foam or paper towel down so it can't slip and it's not gonna rotate. That's gonna translate more of that energy forward isn't it? So it's faster on a grippy surface. No? Yeah https://casinoslots-sa.co.za/rich-casino? On the felt surface the bottom of the domino is slipping backwards again but it catches due to higher friction. So the question is, because it's slipping less, does that mean the whole line is going to topple forward faster? So just did a hard plastic and a clear plastic side-by-side and right at the end you can see, it's very very clear... It's very clear there's a difference. Back it up, back it up. Did you see the clear in the back? The clear plastic ones kick out more so maybe yhey're slower Do you want a domino to grip or not grip? Dunno... So clear dominoes are heavier And they go faster. That - that is counterintuitive. So it's 4 A.M. Smarter Every Midnight Okay look I feel like I owe you an apology because on Smarter Every Day when I break out the High-Speed camera It's like the mysteries of the Universe are revealed but when I turn it on this little block of Plastic. We only get more questions. For example the first 20 dominoes in our setup - it's Accelerating so we're not getting a steady state velocity of the topple until after that so i think My setup is inadequate to do what we're trying to do. I mean, also the fact that this thing Doesn't pivot like a hinge like every research paper says it does, it slips we're in an area of Physics now called Tribology which is the study of two frictional services in relative motion. This is complicated. There's a lot more Greek letters in the math now Another thing, like right here, the way I've been triggering this, I've been touching that That's inconsistent how I'm doing that. If you have better ideas I Feel like we need to redo this entire setup and do it right so If you would leave comments below on ideas for how to trigger that, Things on the setup, I want to do this right but for right now I mean we've done complicated things on Smarter Every Day But the simple domino, the Simple domino is a challenge. It's hard stuff Did you know that each time you buy a Casper you get a free time machine? SON>> WHAT? DESTIN>> I want to thank the sponsor for today's video which is Casper. You can get a mattress at casper.com/smarter Tara and I have slept on a Casper for over two years Everybody asks me face to face "are you just saying that on YouTube or do you actually like it?" Of course I actually like it which is why I got one for the guest bedroom Which my daughter took over Now we have one for the boys. So if you want a mattress go to casper.com/smarter use the promo code smarter to Get $50 off. There's a lot of cool things about it they'll ship it directly to your house you get to open it up it's kind of fun. Also you get to bypass the mattress company in the middleman so you get a high quality mattress for a less expensive price. It's a good thing. There's multiple types of foam so you get the right balance between comfort and Support without it being too hot and you get a hundred nights free trial if you don't like it, they'll come pick it up at Your house you don't have to worry about it. This is my favorite part. I'm not just saying this, I actually do like the product and when you support the sponsor You support Smarter Every Day which allows me to do things like support the Zeal Incredible Science Machine which is a really cool way for really neat smaller YouTube channels like Lily and Steve To create videos that they love. They make good stuff. I think the reason it's so good is because they are Seriously passionate about dominoes and that is contagious. It's your support of the sponsors that make that sort of thing happen so thank you very much. Also Go check out that video in the second Channel. It is rad. It's a long video But I learned stuff I have never ever thought about in my entire life. New stacking methods, how they index them, the speed of dominoes? It's really fun I think you'll really enjoy it. Feel free to subscribe if this earned it, if not No big deal i'm Destin and you're getting Smarter Every Day. Have a good one now. Thank you very much for letting me do that so this you did that last year too right? LILY>> Yep DESTIN>> You know i'm actually changing the logo on Smarter Every Day after this video. This video is like the last video using this logo. It's going to be something similar.
