The blue one.
Then there's Dragon Ball Z where it started to become cheasy (but still fun).
Assuming the ball is a perfect sphere of uniform density, and is suspended from a massless string, the centre of gravity is in the centre of the ball.
The jump ball area is in the centre of the basketball court.
a jawbreaker
Netball is started with a Centre pass. Only the centre and the opposing centre are allowed in the centre third. All other players will stand outside the third and wait for the whistle. The ball must be received or touched in the Centre Third. After a goal is scored the defending team will take the centre pass and the game is restarted with the teams taking alternate centre passes. If there is an interception by the opposing team and a goal is scored this team can take the centre pass. So intercepting is important. Netball is started with a Centre pass.

Replacing the steel ball with a wooden ball would slightly reduce the period, a lead ball would very slightly increase it and a ping pong ball would reduce the period substantially.The period of the pendulum is proportional to the [square root of] the length of the pendulum from the pivot (hanging point) to the centre of the mass of the string and the bob. For a dense material like steel or, even more so, lead, the weight of the string is negligible and the centre of mass of the-string-and-bob will be at the centre of the bob so that the effective length of the pendulum would be from the pivot to the centre of the bob. With a ping pong ball, the mass of the string is no longer quite as insignificant and so the centre of mass of the-string-and-bob will be higher than the centre of the ball and so the effective length of the pendulum will be shorter.
Prior to a game of netball, there will be a toss. The winners of the toss will usually take the centre throw. A game of netball then starts when the winning team's centre (C) has stepped into the circle and thrown the netball.Also all players must be in the correct positions and no feel in the semi circle or into the middle third,except for the centers(c)
It is quiet hard. It has a cork centre, covered by leather. So it is harder than a tennis ball, but not as hard as a Baseball ball or a cricket ball.

a centre pass is where theecentre takes a pass from the sentre of the centrethrid, but it must betouched in thecentre third before it goes/rolss into the goal thirds
A roller coaster on the rails, water, still ball :D
