Totally impressed with your dedication to the 20 sided dice Matt, fab

One of the things you can learn from other crafting disciplines is how to make a cane with no air bubbles - polymer clay artists and candy makers know how to do this well. Basically, you squish the very middle into a smaller diameter and then work your way out like you're squeezing a tube of toothpaste but on all sides of the cane

I want to say this was pretty cool; but I also want to say that what you created was a spin-down d20, not a rolling d20. Spin-down d20s are used to keep track of things, like if you're playing Magic, you can use a spin-down d20 to keep track of your life points, but the numbers aren't sufficiently randomized to be a good rolling d20. It would be comparatively easy for a person to develop a rolling technique that makes it likely for the die to land on a relatively high score, if all the high numbers are grouped together in the same part of the die. For randomization purposes, regardless of the type of die, all opposing faces should add up to the same number (if there are opposing faces), to sufficiently balance the odds, and there should be as much space as possible between successive numbers.

Love these! Would be great if you could send them to Stand-Up Maths to work out how well balanced they are. Surely they're close enough but I'd be really curious to learn a method to measure that and find out just how close they actually are.

Quick PSA-- For "inking" pips(dots on dice) or numbers, brush on nailpolish then whipe off on a paper towel on a flat surface and you get great results and a massive about of awesome colors!

Huh I suppose you could use a similar method to make dominos - cool dice - love your channel

given how soft these kinds of plastics are i could also imagine theyd be great for some very colorful woodcarving-esque projects. actually thinking about it more, the pattern on the plastic already kinda resembles woodgrain in a way so if you pick only similar colors it could actually give off a very cool colorful wood effect

a lot of people dont realise that the opposite numbers on a dice shoud add up to 7, ie 4 should be opposite 3, 2 opp 5 etc

We’ve made so much in our family using crisp packets and milk carton lids because of you guys xx we spend so much on our D&D dice so this idea of making our own is brilliant. 😊

LESS twisting and folding = more air bubbles, more color contrast MORE folding = less air bubbles, less color contrast

What a fantastically geeky project, I love it! Could I make a suggestion? Instead of a silver marker, a Molotow chrome pen would really make the numbers pop. I use them in my action figure restorations (my contribution to keeping plastic out of landfill I suppose!) and they really are properly chrome, not like the old days. You will need to fix the chrome when it's dry, so might add a couple more minutes to the project, but it'd be well worth it. Also, just wanted to say how nice it was to meet you both at MC in May! My Mum was very impressed by the sunglasses after I'd explained what you lads do! It'd be amazing if you could do a talk next year, I'm sure loads of people who don't know what you're about would love to hear what you do, how you do it and why. Fingers crossed!

I know I commented earlier on the need for precision in dice, but had an afterthought that I wanted to share. When I was young, back before televisions were in color, we had earrings made of dice. Why couldn’t you add a screw in I-ring into the dice, add a jump ring and put them on hanging pierced earrings? They were hugely popular back in the day. Precision isn’t important and since the kids play so many dice dependent games, you would have a market for them? Just a thought.

I love everything about this video, and your brotherly relationship is refreshing and enjoyable. I know nothing about recycling yet, but I am now inspired to study!

There is no way thoes are weighted properly. I did find this video intresting and fun. The D20 was right up my color alley. I've subscribed. 👍

That is absolutely awesome! How long did the D20 take? Would you have been able to get similar color patterns in an injection scenario? Or do the colors mix too much?

Air bubbles inside a dice will throw it off balance and make it unfair. More blending would be better in this case.

That was perfect. I should melt plastic and make dice. That gives me excellent idea.

The pattern you used to number the d20 is a spin down, as consecutive numbers are near each other, making it a good dice to keep track of a number, like health points. For rolling you should use a different pattern where consecutive numbers are almost opposite to each other to ensure your rolls are more or less balanced even if the dice isn't perfectly fair

13:58 Other comments have dealt with air bubbles affecting randomisation, but you may get comments here that this is a spin-down dice (a dice where a path exists from face-to-face from the highest value face to the lowest value face) which I hear from the magic the gathering community is not a fair dice. Note - if everyone uses the same physical dice, then you are drawing from the same random distribution and no one in particular is favoured. Edit: Stealing from my Parker dice, if someone wants a fair distribution, spinning down, the sequence is - 20, 6, 3, 7, 16, 4, 2, 10, 9, 8, 17, 19, 11, 12, 13, 15, 18, 14, 5, 1. Edit edit: while I'm writing an essay in the comments, the "Matt Parker" dice is the product of the dicelab which Matt showed off in his video, of which an explanatory video can be found here: https://youtu.be/Nh2H_4g6evc?si=w1AP8MVgrXtjjY_T
