Hi Porshe!

Some people use mirrors in the fountain basins to mimic water flow in the Winter if they have to turn the water off due to intensely cold weather. Otherwise, anything that has a directional feel to it that reminds you of water would be appropriate.

I assume this is a fountain for the Water Dragon? If you're actually activating for a flying star, you could use an indoor fountain during the Winter, and then turn on the outside one in the Spring, Summer and Fall.

All the best!
