Actually, I'm pretty sure its creation of water/Fire, which is impossible according to science (Unless you're a monothesitic GOD, the only other option is energy to matter, which again physics says you're most likely not going to accomplish this, unless you have a LOT of energy or are a creator GOD)

Hydro (Water) Genesis(beginning)

In short closing, you need a lot of energy to make only a little bit of water, or have to be GOD. Either way, most people likely can't accomplish this.
