       I don't think a tiger will actually fit. When you see them on TV, they're actually a lot smaller than in real life.

       Clear bowling balls with all sorts inside them exist. See <link> with a skull. Personally, I like the idea of a liquid- core, maybe one of those sealed-ecosystem things with shrimp inside would be fun. Unless they don't like shocks.

       //I don't think a tiger will actually fit. When you see them on TV, they're actually a lot smaller than in real life.// - couldn’t you just use a much larger bowling ball?

       That would certainly help matters. Or you could use a tiger that's far away.

       // Personally, I like the idea of a liquid core //   

       That would add some interesting behavior to the motion of the ball. [a few seconds pass] Now I see this has already been posted as an idea, three below this one in the same category.

       I have seen glass cubes with stuff laser engraved into their interiors, possibly a confocal effect thing. You could do that with a large sphere. Making the thing once with CAD software then making many spheres could make it less effortful. A pretty math function could be nice too.   

       Then there are those fractal acrylic things from electricity too...

       It’d be interesting to put a generator inside, to generate and then store power from the thrust. It’d be interestingly interesting to make this generator eccentric in a sort of – well, whatever the term for a 3D kind of epitrochoid or peritrochoid (ie, that is epitrochoidal in X Y and Z).

       //to generate and then store power from the thrust//   

       Or to change the direction of the ball, but all you'd really need there would be a hamster.

       Wonder if you can make a ball that rolls down the lane slowly, but building up potential energy that's put back into motion that speeds up the ball at the last second to hit the pins with most of the energy that the bowler put into it.   

       For some reason.   

       How about a 360 degree LED screen that shows an animated image of flames or sparks once the ball senses it's rolling?   

       For some other reason.

       [dr3] Strike ! That's 2 patentable ideas in one anno.

       // building up potential energy that's put back into motion that speeds up the ball at the last second to hit the pins with most of the energy that the bowler put into it. //   

       "Most" will be doing well. No energy storage system is perfectly lossless, outside school physics textbooks*. So if the ball sets off with energy E and some is absorbed and stored, then reapplied to the ball, the final energy will always be E - deltaE. The remaining energy will be dissipated by frictional heating, air turbulence, or stolen by the tiny green gnomes that live under the bowling lane.   

       However ...   

       The air resistance the ball experiences is proportional to V^2. If the ball is released with velocity V, and rapidly decelerates to V/2, then the air resistance - hence the turbulence, and energy loss - will be proportionately diminished (square law).   

       So a ball that slows down, then speeds up for the final impact, might make some sense after all. It depends how much air resistance contributes to the overall deceleration down the lane. It's probably quite a lot, as the rolling contact resistance of a smooth inelastic sphere on a smooth inelastic surface will be very small.   

       *Or indeed geography textbooks. It's been established that geography textbooks hurled at students by aggressive, psychotic geography teachers can actually strike the victim with more energy than they started with. This is because all geography teachers have turned to the Dark Side of the Force, and are Twisted and Evil.

       //"Most" will be doing well.//   

       Yeah. But the spirit of the idea is to ignore the inputted energy if you're already filling the ball full of gubbins, and use the inbuilt battery to - speed up, change direction, take off etc.
bigsleep, Feb 05 2019
  

       But what's the mechanism to store that energy? How do you store some percentage of that energy to put some percentage that energy stored over say, 90% of the roll into a last split second surge?   

       Without having anything like wheels or plungers extend out of the ball at the last second, all has to be internal.   

       The only air friction model I can see is if you have a drag chute with a heavy weight on it attached to rubber bands that extends out as the ball rolls, then snaps back with the weight and hits the ball at the last second putting some measure of energy back into the forward movement.   

       Seems very inefficient. Obviously due to the storage/retrieval loss you're better off just letting the ball roll with any system.   

       I'm thinking a spring in the middle with a counter weight that spins the other way when the spring reaches its extent. It'll be spinning the opposite direction in the middle then gears engage at the last second turning that rearword motion into forward motion.

       //Without having anything like wheels or plungers extend out of the ball at the last second, all has to be internal.//   

       Imagine a ball within a ball. The inner ball is locked in place by electromagnets - otherwise its free to rotate in any direction.   

       Throw ball - inner ball electromagnets decouple leaving the inner ball to rotate at initial throw velocity. Outer ball decelerates with air resistance. After so many rotations, the electromagnets are re-engaged and the outer ball equalises velocity with the inner ball and speeds up. (And thats without a motor).
bigsleep, Feb 05 2019
  

       You could also "spin up" the interior ball and have it engage at the last few seconds to hit the pins with cannonball force.   

       Could do it the opposite direction and have it act as a brake as well. Not sure why you'd do that but "Why?" doesn't figure into this.
doctorremulac3, Feb 05 2019
  

       //You could also "spin up" the interior ball and have it engage at the last few seconds to hit the pins with cannonball force.//   

       Steady on now, that kind of reactionary force would require some external rubber treading.
bigsleep, Feb 05 2019
  

       Yea, guess these are pretty slippery, it'd just slide slightly slower.   

       But if you did use rubber it might make a cool squeeling sound.   

       Ok, here's the idea. Screw the original idea.   

       Actually I'm going to post a new idea because this is so brilliant.
doctorremulac3, Feb 05 2019
  

       //No energy storage system is perfectly lossless, outside school physics textbooks*   

       So, logically, a bowling ball with a school physics textbook attached to the inside...
