Hummingbirds love water, so if you’d like to make these birds extremely happy then put out a water mister on a timer that turns on at a certain time of day. The birds will quickly learn what time to arrive for a bath.
Another option to entice hummingbirds with a water feature is through the use of a birdbath. The birdbath should have a very shallow water depth to allow the birds to stand in the water if they choose to do so. Adding some small flat rocks to the birdbath will create different water depths within the birdbath.
