Great video! Of all the things I took apart while growing up (My wife says I still haven't grown up!) I never cut my 8 ball open. It's long gone now so thanks for cutting one. I really wonder why the interior container has that complicated cap. Maybe the design was to stop splashing and inconsistency during the fill. Probably also designed to fit the filling machine and it has a smaller opening to seal on the production line. Please keep making great videos! We'll keep watching!

Two things about the capsule cap: The cone-and-chamber design traps air bubbles out of the way of viewing the text; some air is needed to buffer pressure changes from temperature swings that could cause leaks. And the cone enforces a tumbling of the die to help prevent repeat answers. Since opposite sides of an isocahedron are parallel, if the float chamber had parallel ends as in the patent drawing, the die might not tumble reliably. With a cone shaped capthe die will float with a corner up, meaning also a corner is pointed down. Inverted, the die floats to the viewing window point first, then tumbles to a flat.

Will the band somehow notice me? -Don't be on it. I think that's cool.

Hi mrpete, The 20 faced part is probably made of some Polyethylene type plastic where the density is a little less than water so it floats, the liquid has to have a density around about 1, so, it's probably water with die and anti-bacterial agent or stabilizer of some sort. Interesting how simple it gets after being refined enough to be manufactured in large quantities.... Pierre

I had a Magic 8 Ball when I was a young boy. Unfortunately, It fell victim to my insatiable desire to take things apart (as many of my toys did). Since, as you pointed out, they are very well constructed, I probably just threw it on the ground until it cracked open. Maybe I got into Dad's tools and pried it apart with a screwdriver after I had a crack started. Seeing that jar you sawed open makes me think it's made of poly-carbonate, which would have been a challenge, especially for a young boy. I have no regrets though. I learned how lots of things like electric motors, gears, and music boxes work.

Shape of the "cup" is interesting. It makes it so that amount of air left in container during assembly doesn't matter "much". Can't have lots of it, but some air doesn't matter.

Thanks for this fun dissection. I don't quite understand the function of the complicated funnel like shape of the white plastic portion of the fluid container. It must have to do with controlling the flow of the liquid in and around the dodecahedron for effect. It would have been interesting to replace the fluid with water containing floating particles to watch the flow. The real trick is getting the ball to float, not too fast or too slow, and not to sink. It surprised me that the fluid will get inside the dodecahedron as it is two piece and hollow. Is the fluid thicker than water? Thinner?

The word is icosahedron (means twenty-sided, just like tetrahedron is four-sided). It is one of the five Platonic Solids, which each have all identical faces and meeting angles at the edges and at the vertices. Perfect symmetry any way you look at them. Tetrahedron (four equilateral triangles) Cube or hexahedron (six squares) Octahedron (eight equilateral triangles) Dodecahedron (twelve pentagons) Icosahedron (twenty equilateral triangles) It has been proven (in several different ways) that there are no other possible Platonic solids. There is a good Wikipedia article which has much more information, including (for those with fancy CNC equipment) a listing of the Cartesian coordinates of each of the vertices. With that, you could mill each one out, once you figured out a way to clamp it down to machine the underside of the piece.

It's a bi capped pentagonal anti prism otherwise known as an icosahedron. You referred to it as a prism which is pretty close. A pentagonal prism is formed by spacing apart two pentagons and rotating one pentagon so that each of its 5 vertexes align with an edge of the other pentagon. A dot is placed over the face of a pentagon and lines are drawn from each vertex to the point to form a cap. The same is done on the other pentagon to form a second cap. Now you have a bicapped pentagonal antiprism. This may be better understood by considering a trigonal prism which is familiar to most people simply as a prism. (The one that difracts light into a rainbow of colors.) Each vertex of one triangle is placed in registration with a vertex of a second triangle. If you were to rotatate one triangle of the prism so that each vertex aligned with an edge of the other triangle you would form a trigonal antiprism. If you were to place two caps on you would get a bicapped trigonal antiprism. I was shocked by the complexity of the Magic 8 Ball. Great video. BTW, I used to work at that local nuclear power plant you refer to in some of your videos--Lasalle. I think its address is in Uitca, IL. I would pass through Streator from time to time.
