If watermelons are 90% water, couldnt there be a way to separate the water from the other substances? And if it is possible then couldnt we be able to "grow" water?

Cucumbers and other vegetables and fruits also have a very high water percentage, and the water from all of them can be extracted by pressing (I'm wondering if a centrifuge might work, as well). It's not practical, however, because it takes more water to grow a watermelon than the watermelon contains. Water is used and lost in respiration, and fills the leaves, stems, and roots as well as the fruit.
It would be far more practical to conserve the water we already have, and take steps to harvest rainfall. It's commendable, though, that you're thinking about it!

You can separate the water out of the melon by pressing it, you want have much left when you are done. You can not "grow" water, all the water on the planet is all the water their ever has been on planet Earth since God created it.
