Sphericon Bowling

Having just heard about sphericons today.....

A sphericon would certainly make an interesting bowling ball, owing to the odd way it rolls.

It would be interesting to watch sphericons roll down a track, trying to hit some pins.

       What you bin smoking [DF]? This is an absolute corker, I couldn't imagine anything sillier.

       I had a whole idea ready to go on this, only I called it sphericon skittles. I researched all the regional variations of skittles. You can't put a lot of force behind a sphericon like you can a bowling ball. Just a little push. Otherwise, it will skid and tumble. So sphericon skittles is played on a sloped alley.   

       The only reason I didn't go with it was, when I tested out the sphericon on an inclined plane, the direction it went in was pretty much determined by the direction it was set down in. Once you learn the correct direction to set it down in, you're pretty much just watching the thing waddle. It's a little random, which makes it a bit like pinball, but slower. If you increase the incline of the plane to speed it up, the thing just tumbles. That's why I did the sphericon toy instead, which also makes use of the peculiar way the spericon rolls.

       Sphericons might have nice mixing properties. See animations of sphericons rolling against eachother on the Collin Roberts website. Thos edges sort of act like little blades. Also there's an oloid mixer on Google Images that you put stuff in, and it mixes it up. (link)

       Where did you get a sphericon from?
wagster, Feb 16 2005

       [Wags], I cut it out of paper. There's a pattern on Roberts' website. Not heavy enough to simulate a bowling ball, but interesting.

       The link works now.   

       Those gears are amazing.

       I think that the Egyptians are way ahead of us in Sphericons. It is Egypt's closest guarded secret. They roll them away at night before we can see them.   

       It's how they get the wavy sand dunes.
