LEGO Great Ball Contraption at BrickCon 2022 

Agreed

very good, actually, we've seen their cunter, it is 10.000 balls and more, and I don't think they have more then 1000 balls there. If one ball needs 12 minutes (so 4 circles per hour), and show goes for 8 hours, it is 32 complete circles per day - we don;t know at what moment Joshua approached them (start, middle, end) and how many days it was counting, but let's presume it is middle of the day, working for 6h, and math is one ball was counted 70 times - meaning they have 142 balls on the table, plus spilling. So, I guess they have 500-1000 balls on the table (maybe they will reply to us:)

There's a number of ways to determine the odds; the one used by Ivan is both accurate and reasonable. In the spirit of GBC, here are a few of the more outlandish/overcomplicated methods. 1) The probability of a successful full circuit is the product of all the modules individual success chance. If every module passes 99 balls out of 100 and there are 500 modules then the total odds are {99/100}^500. If you put 1000 balls into that theoretical machine 6.5 will come out the other side. The actual contraption is obviously does much better than this, yet it's equally obvious some modules drop more than 1 ball in a hundred. Other modules are better by an order of magnitude, losing one in a thousand. So to get an accurate answer with this method you have to know what every individual module's particular success rate is, then do a huge calculation. You could have each builder run tests at home then submit the data to a shared Google spreadsheet which would sum the odds. 2) You could follow a particular ball through a complete circuit and every time it falls out of the machine you put it back in. The final odds would be one divided by the number of times the ball entered the machine. The answer will be wildly inaccurate due to the small numbers problem. If the ball never falls out during it's journey the odds are 100% but if it falls out twice then the odds drop to 33% 3) You could start with the machine completely empty and run a single lot through it. Add, say, 1000 balls to it and collect them after they've finished their heroic journey. If 984 emerge from the other side then you know the odds are 98.4% and you pay your respects to the 16 that fell along the way.

@@oliverdarvell litterally, staggering. like staggered staircases.

@@FRACTUREDFUNGI lol

🤩🤩🤩🤩🤩👍👍👍👍👍

That was exactly my thought, such a simple fix on a couple of these.

maybe they will see and send a link, it is interesting for me too

Welcome back. We are still going strong!

@@BeyondtheBrick HE RESPONDED??!??!?!?!?!?!??!??!?!?!?!??!

That ball factory was made by my friend Akiyuki

@@ToothlessThedragon9 Awesome! :) It was my youth :)
