6. Put a bead of silicone caulking around the inside of the outer container. Slip the shallow bowl into the outer container, fitting its drain hole over the plastic tubing; trim the top of the tube so that its end is flush with the bottom of the shallow bowl. Make sure the bowl's rim has good contact with the caulking. Allow the caulking to dry overnight.
7. Put landscaping rocks around the pot to hide the mesh.
8. Fill the plastic bucket under the fountain with water, and turn on the pump.
