You really are a pathetic dope, incapable of reading aren't you ! A kindergarten drop out. Get your mommy to read the bloody thing to you, fucher.

For others who are capable of reading, the authors of the paper, Li FX, Margetts S, Fowler I (not me) claim:
"... Finally, water had no significant effect on the coefficient of friction. The counter-intuitive effect of chalk appears to be caused by two independent factors. First, magnesium carbonate dries the skin, decreasing its compliance and hence reducing the coefficient of friction. Secondly, magnesium carbonate creates a slippery granular layer. We conclude that, to improve the coefficient of friction in rock climbing, an effort should be made to remove all particles of chalk; alternative methods for drying the fingers are preferable."

Merry Christmas.
