I dropped my iphone in water, and I don't have rice?

The only thing that seems to be off is that I can't hear the clicking of typing when the sound is on and when I use the volume button, it just says ringer and doesn't show how loud my phone is… Everything else seems to be fine

Can I use something besides rice?

Just let it dry or try putting it in front of a small fan for a day or two. Rice is somewhat of a myth, a small fan would probably work better.
