Why are water molecules attracted to each other?

I think: Water is covalently bonded. This means that is has no positive and negative charge (unlike ionic bonding) However from time to time water molecules split into "one hydrogen" and "one hydrogen and one oxygen molecule" this therefore gives water attraction to both positive and negative charges as the two separated parts are charged differently. Remeber i am unsure of the validity of this answer I hope it helps Saeed Al Hakeem Uk seedy it is a polar molecule
