Liquid Filled Bowling Ball

Find the exact weight that you want by draining or adding liquid via the finger holes. Of course there is a plug to stop it from leaking.....

Bound to be some interesting and possibly benificial effects from the swirling liquid inside.

       [+] Regardless of the game benefits, I imagine that the liquid sloshing around inside would be awesome to look at. The combinations of different viscosities and colors would be cool too...

       Reminds me of the floating skull encased bowling ball from Mystery Men.   

       Due to the fact that the liquid will be hard to acelerate with the shell, it will keep from transfering forwards energy into rotational energy...
It will be harder hitting.

       Jeez. Sometimes I think I need to sign up for physics to understand some of you guys. No offense...
Pocketassreturn, Jun 19 2004

       <Translation> Water will slosh, not roll good.<Translation>   

       remember the spinning egg test to check if an egg is hardboiled or not? A ball filled with liquid wouldnt go very far, unless filled with something thick like mayonnaise, but then it would never go as far as a solid ball. A liquid filled bowling ball might have some value as a piece of training equipment.

       cool link.

       Astonishing that no one's suggested custard yet as ball-filling medium.
hippo, Jun 20 2004

       Yeah - see if you could pass that by PBA officials.   

       Gosh-darn nice drawing, BTW, [2 fries]!

       Not mine. I tried to find a still from the movie and that sketch was one of the first hits.

       How true......   

       I'mmmm baaaaaaaack!!!!!!!!!!!!!!!!!

       [Evildave], bowling balls DO have eccentric weights in them. That's largely why good bolwers can make them curve so much.

       Put a 2 Kg bubble of mercury in the ball. Then get the mercury spinning by setting the ball in a bowling ball spinner (which DesertFox will haffbake tomorrow). Then roll that sucker down the lane and see what happens. I imagine that if the spinning mercury doesn't rip your hand off during your approach, it'll make the ball do funky twirlie things as it rolls. Mercury's cool!

       [+] just for the mercury.

       I know that bowling balls do have off-center weights, but my impression is that a bowling ball is required to function as a rigid mass. The only way I can see a liquid-filled bowling ball as being acceptable would be if it had spring-loaded pistons that held rigidly any liquid contained therein.   

       With that change (using five pistons, so as to allow the mass, center of mass, and moment of intertia to be set arbitrarily and independently) this would seem like a promising idea. Even if a ball constructed in such a fashion could not be used in sanctioned tournaments, having a ball that could be easily modified could nonetheless be useful for high-level bowlers, since it would allow them to experiment to find what exact combination of factors would work best for them. Once they found that a certain combination of weighting was optimal for them, they could then have a ball custom-made to those specifications.

       mercury is dangerous.
mailtosalonga, Sep 15 2005

       But not as dangerous as Venus.
wagster, Sep 15 2005

       Nor as dangerous as Serena.
sleeka, Sep 15 2005

       The single best liquid to fill the bowling ball with is beer. Homer Simpson did this. What was good for him should be good for us.
Gusbus, Sep 15 2005

       Could you get around the sloshing effect by having hundreds of thin metal baffles inside the ball?   

       Otherwise I'm sure someone could work in custard somehow.
Adze, Sep 16 2005

       If I had that I would have to fill my ball with sand then I would add water to make the ball a good 30 lbs or so. You wouldnt have to roll it very fast or very hard for the weight and mass of the ball to knock down all of the pins indiscriminately.
