You miss that one Are you frustrated, Trent? No, all right! We'Re going to figure out exactly how to nail this we're gon na get all the dominoes in frame as they fall. So we can gather the timing, data and figure out what steady state velocity is. It took some practice because sometimes the dominoes would outrun us And sometimes we outran them.
So I keep messing up the high speed, which means Hayden has to keep set up dominoes, Which means up. If we're gon na my half-court shot, We got it. It'Ll work it'll work, this data.
This is the first good run. We got on felt Watch closely and you can see that the bottoms are trying to slide out from under the Domino, But it digs into the felt and stops. I think we got it do that one more time.
I feel really good about that. Oh, we did pretty good Hayden Hayden, We got it, that's the one right. This is the best run we got on hardwood https://casinoslots-ie.com/casino-x.
If you look at the bottom, you can see that It's slipping out from under the Domino makes it rotate around its center of gravity and also, if you look at the top, you can See that they're not hitting square on So which one is faster. We'Ve got hardwood on the bottom that slips and we got filth up top that doesn't slip and Trent and I both felt felt Was faster. So how do we know we have to like quantify this? The answer is brute force, science.
To figure this out, We did a ton of runs mostly filmed at 5,000 frames per. Second, the goal is to figure out exactly What millisecond each individual impact occurs, which made for over a hundred and twenty thousand frames of data to reduce Your boy. Here has too many kids and too many jobs to reduce that much data. So I blasted out a spreadsheet template to everywhere that smartereveryday touches the Internet. I compared you guys against each other.
Twitter Got it done fastest. People follow me on Instagram and snapchat got it done quickly. Facebook helped, surprisingly, the physics subreddit wasn't interested in doing physics.
That day, the smartereveryday subreddit was great and accurate, but Patreon was by far and away the most accurate source, which makes sense, because these are the best people in the world There's a reason I gave each social media outlet its own spreadsheet. It'S called the wisdom of the crowd here. You can see exactly what frame each individual chose at the impact point and the average of those selections. These averages were then graphed for each individual video file and there you have it if you average all the runs together. It appears that The non slipping felt is faster than the slipping hardwood before I go into why I think it's faster, I'm gon na let grant from the YouTube channel three blue one brown take a crack at it, because this dude is fantastic at reducing super complex Mathematical systems down to quick, little YouTube bytes. It'S amazing!
You should check his channel out anyway, go for it, grant Hey Destin its grant. So I wouldn't haven't. Looked at some of the data that you sent and here I'm just gon na pull up two examples. One of them with Domino's on felt the other on hardwood, and these are just the plots of the average velocity of each individual Domino as they fall, and Obviously the first thing that stands out is just how chaotic this is right. They'Re super jaggedy, and I think some of that might just be that the Distances between each Domino were probably a little bit variable right.
Okay, let's just get this out there right now. I know This is weird. You probably watch this channel because you want to see slow motion phenomenon of like bullets hitting stuff and fracture mechanics and water drops bouncing and animals squirting things Whatever you're into, But this is crazy. Most people think ``. Oh look!
The cute little nerds set up the dominoes and they knock them down and everyone claps and it's great .''. No. This is different than that. I was naive enough to think that I was gon na set up a high-speed camera point'em at dominoes. I was gon na set'em up, knock'em down vary the spacing and the type of floor it was on and I was going to transcend the knowledge of dominoes instantly. You were gon na get smarter every day and we were gon na go about our merry way, But no Look me in the eyes This has broken me.
I do not understand dominoes. The reason this's broken me is because I've been sitting here doing all this math to determine the gap Necessary in order for this red Domino's weight to always knock over the blue one. But when I set up with my calipers, It doesn't work and if you think about it, the same people that taught me how to do this. Math Also told me if I needed to, I could assume a cow is a sphere in a vacuum Paper. Physics can only get you so far.
If there's anything I've learned from my job as an engineer, It's that There's no replacement for actual real-world testing. If we want to make observations of the exact times these Dominoes hit down to the millisecond, It's really hard to do it from a camera. Like this, the reason is look over here.
You can see the inside of this Domino and then the inside of this one and somewhere in the middle. It changes. So if we want to get a shot where we get all this data, We have to have a moving camera, not only that, but a moving camera. That is Perfectly timed right here in the middle, so we can see when this edge hits this edge, Which means we're gon na have to time it perfectly With the wave of Dominoes as it runs along the track.
Do I want to keep making videos on smarter every day about Dominoes Yeah? If that's what it takes to find the answer? Yes, that's what I want to do This is about not quitting so now we're gon na give Domino's the respect they deserve and we're going hardcore mode. We'Re at fifteen millimeters. The second one over here Welcome to hardcore mode .., It's the same as before.
Only I try harder so here we go we're gon na build stuff And we're gon na do experiments and we're not gon na quit and there's a twist at the end of this video. Let'S do it. Okay, this is Trent.
He is the contraption fabricator that I talk about on the patreon page, and this is my cousin Hayden, hey Hayden, okay, so this is a high speed camera on a skid and Trent made this good job Trent, and we are about to try to pace These dominoes. So that we can tell the difference between a hardwood floor - and you know a surface - that's grippy, Okay, ready That looked awesome! Oh it outran us! It moves a lot faster than the wood floor and I'm so used to the wood floor. He'S frustrated. I know well enough to know when he's frustrated He's frustrated.
Chicken foot, also known as Chicken dominoes, Chickie dominoes, and Chickie, is a dominoes game of the "Trains" family, similar to Mexican Train. Chicken Foot is played in rounds, one round for each double domino in the set. The game is normally played by 2 to 8 players using any of the common sets (double-six, double-nine, double-twelve, double-fifteen or double-eighteen). If a player does not tap their last domino on the table when they are down to one and the next player plays a domino they must draw from the bone yard. == Objective == The goal of the game is to have the lowest score by the end of the last round. For each round, the goal is for the player to empty their hand of dominoes by playing them on the board.
== Setup == The dominoes are first turned face down and shuffled. Then, each player picks seven dominoes to form their hand. With more than four players, the game requires an extended set.
The number of dominoes drawn can be increased when fewer players are using a larger set (for instance, four players using a double-twelve set can draw 15 dominoes). Any remaining dominoes are placed to the side, forming the boneyard. == The First Round == The round begins with the highest double being placed in the center of the layout to start the game (using a double-twelve set, this would be the double 12). (In each succeeding round, the next lowest double is found and placed as the starting point: 11, 10, 9, etc. until the last round using the double blank). In the first round only, everyone draws a single domino from the boneyard.
The player drawing the highest value begins the round and everyone returns their drawn domino to the boneyard. The starting player must play a matching domino (one with an end of the same value as the double) from their hand on one of the four sides of the double, with the matching end against the double. The next player plays another matching domino on a remaining side, and this continues until all four sides are filled. If a player cannot play because they do not have a matching domino, then the player must draw one domino from the boneyard. If that domino does not match, their turn passes to the next player. No other plays can be made until all four sides of the double are filled.
Once all four sides of the double are filled, the player to the left of the last person to fill the double can play any domino in their hand that matches an exposed end of a played domino. If a player is unable to match any exposed dominoes, they must draw one domino from the bone pile and either play it if possible or pass. If the boneyard has been emptied, any player who cannot play simply passes. If no player can play or draw, the round ends. == Chicken Foot == Any time a player plays a matching double on an endpoint, the player calls "Chickie (Number)" to indicate they have started a new "chicken foot".
For example, if a player played a double 4 on the end of a 6/4 domino they would lay it long side against the end with the 4 and call "Chickie Fours". No other dominoes can be played until three more 4's are played against the other side of the double 4. The three dominoes played against the double 4 are played on the long side opposite the side originally played.
The end result will look like a chicken foot (hence the name of the game) with the double having one domino laid perpendicular to one side, and three more dominoes on the opposite side, the middle being perpendicular and the other two at 45 degrees to perpendicular. Any player who does not have a domino matching the played double must draw a domino from the bone pile and then play it if it matches or pass. Once three matching dominoes are played to finish the chicken foot, the next player may play a domino on any matching endpoint, including any of the three branches of the new chicken foot. == Ending a round == A round is over when either one player plays the last domino in their hand or no players can make a legal play.
The latter situation can occur if someone plays a double that no longer has three remaining free dominoes to play on it and the boneyard is exhausted. At the end of each round, each player sums up the spots on the dominoes in their hand, which becomes their score for that hand and is added to their running total. In each subsequent round, the highest double drawn that has not yet been used to start a round starts the next round. When a round for each double has been played, the game is over and player with the lowest score wins. A game cannot end in a double.
If it does, the player who plays the double gets 50 points. A player who holds the double blank in their hand at the end of a round gets 50 points, but a blank half has no value other than the number on the other half
