This was a gift to Maralee and we tried it
in the bird bath with a spray nozzle the
first time and the wind blew the water over
the edge and emptied the bath in about an
hour! I looked around for something deeper
and we found this old water feature barrel
and decided to use it, took off the sprayer
and am just letting it bubble, works great!

I tied some washers on a line to anchor it in the middle!
