It depends what you mean by weigh less.
* If you are referring to its density, cooling it below 0°C at Standard Temperature and Pressure will freeze it, and reduce its density (boiling it above 100 C again will have the same effect).
* If you are just referreing to the weigh (and not the mass), taking your water to a place with a lower gravitational field than earth's field (eg the moon, or in a space station in orbit) will make it "weigh less"; since P = m g. Where P is the weigh vector and g is the gravitational field.
Beware: heating it to water vapour (or freezing it to ice) will NOT reduce its weight, just its density.

Seperate the water into smaller droplets.. maybe :)

yes you heat it up to a high tempature and you get water vapor .

Evaporate it?

heat it - and turn it to steam?
