When you consider how much everyone knows/ thinks they know about the manufacture of cricket bats, you'd think they'd be more knowledge about the manufacture of cricket balls?

Could it have something to do with the core (cork and filler used) in the ball?

Magnus effect would be drift, rather than swing, but yes aerodynamics is not affected by colour! 'Red' balls don't swing more than 'white' balls. Depends on the ball - seam, lacquer/wax etc. Also swing more or swing longer?

The lateral movement in the air - one of our umps would describe it as "making the ball dance in the air".

I thought that was a given. Isn�t that white ball cricket is just hit through the line?. The white ball swings for the first2 overs if you�re lucky. A well looked after red ball can swing into 40? Overs.

It hasn't always been thus: A decade ago that chat was all how white balls swung more than red balls. Does no-one remember the ball hooping round corners at the 1999 world cup?

Never use a white ball in amateur cricket - we use pink balls. Can't say I've ever noticed much difference from red balls in terms of swing.

Good question. My understanding is the Magnus effect is the amount of turn in the air I would suppose you could term as swing. I thought drift was the effect of revs on the ball from a spin bowler which would be due to the seam clawing at the air to travel further or dip with topspin. Not saying it is all due to the seam but even looking at a ball in your hand you'd say the seam is the main ingredient.*

*This is coming from a leggie who also uses the rough side to help the ball turn more.

Magnus effect (aka "Robins effect") is the lateral movement caused by rotation of the ball. Magnus effect is what causes drift and dip.

Swing is something different entirely - its caused by the seam tripping the boundary layer on one side of the ball whilst laminar flow continues around the smooth side. It works best in relatively still air. Too windy or too sunny (causes convection currents from pitch) and the ball won't swing.

The core is traditonally made from cork bound with worsted. But I'm led to believe that many cheaper modern balls are not.

I have no idea on differences in the core have on a ball's likelihood of swinging.

I was initially suggesting the difference in colouring process (rather than simply the colour) might be a factor.
