Nowadays Bowling balls are made by plastic, urethane, reactive resin of a combination of them. The evolution of the design of bowling ball refers to density and its nuclei.
One can purchase a black bowling ball from many sports retailers which carry bowling balls. Dick's Sporting Goods carries bowling balls and will have black balls or would be able to order them in.
That would depend on the weight of the bowling balls. If they were 10 pounds each, that would be 700 pounds total.
Bowling balls are typically measured in grams.
It depends on the ball. In most cases, pawn shops would pay you to get rid of their bowling balls and not pay for balls you want to pawn.
If they weren't, the balls would be much harder to aim.
This would be an illegal technique. Your ball would be considered a soaker.
No. A simple google image search would have answered this question for you.
Yes. Gravitational pull is based on mass. And since the bowling balls have greater mass than the ping pong balls then the gravitational pull would be greater.
Bowling balls are made from different materials - either plastic, urethane or resin. Depending on which type you have, it may be possible to burn a bowling ball - but you would sure be making one heck of a toxic waste.
Bowling balls do not have a specific color. Every ball is different and it all depends on the company what color the ball will be. The most uncommon color is probably yellow, there are very few "strike" balls that are yellow, there are a few "spare" balls or plastic balls that are yellow but not many. The most common color would have to be a dark blue, dark purple, or black. Anything on the dark scale would be the most common. That color may be the most common but not by much.
Certain WEIGHTS of bowling balls float. Bowling balls have a volume of 6250 cm3. An equal amount of water would weigh 6.25 kilograms. A bowling ball that weighs less than 6.25 kilograms--8-pound, 10-pound and 12-pound balls--will float. 14-pound and 16-pound balls, having a density higher than 6.25 kilograms, will not float.
