I thought of adding baby oil or glycerin, but I think that would have increased the freezing point of my sprayed mist...I remembered your efforts in these regards and thought I'd be simple. Traveller
I did that once and I remember spraying a fine mist of water on it numerous times once it was approaching freezing. If I remember correctly i mixed in some glycerin to add density to the water. Should you attempt this put it in a box or put some news paper under it to avoid a frozen icy mess in the freezer. Paul
