Water, if left alone in a zero-gravity space (or equivalently, when in free fall), will tend to form itself into a sphere. Since every molecule pulls on one another, and the molecules on the surface have no molecule to pull on them from the outside, this causes what is known as 'surface tension'. This is the reason why one can overfill a glass with water, past the top, by a couple millimeters. Now, since there is tension in the surface, water tries to minimize the surface (it is like a balloon with extremely flexible surface), and since a sphere has the least surface area for a given volume, it forms a sphere.
The Rolling Stones are an English rock band formed in London in 1962. The first settled line-up consisted of Brian Jones (guitar, harmonica), Ian Stewart (piano), Mick Jagger (lead vocals, harmonica), Keith Richards (guitar), Bill Wyman (bass) and Charlie Watts (drums).
By the time Taylor left, they began to call themselves the Rolling Stones, after a Muddy Waters song. On July 12, 1962, the Rolling Stones â Jagger, Richards, Jones, a returned Dick Taylor on bass, and Mick Avory, later of the Kinks, on drums â played their first show at the Marquee. Avory and Taylor were replaced by Tony Chapman and Bill Wyman, from the Cliftons.
