I like the shaking technique, tilt your head to the filled side and pat and or shake it. It might dry out eventually. You could lay down a certain way (not sure which way it is sorry), or you could just stick a few q-tips in and soak up the water. Hope this helps!
Most water will dry up quickly on its own (though we all know it can sometimes still "feel" wet for some time afterwards. Lol hate that feeling). If the liquid is not drying or the "feeling" is driving you batty, there are OTC products available at pharmacies and stores like Walmart and Target that will dry your ears up safely and quickly.
