I was thrilled to receive a package recently with those corn starch packing peanuts - as you may know I have a very strong aversion to styrofoam.
The insert in the package said they would easily dissolve in water. Of course I immediately put one in the sink. It dissolved pretty quick with warm water.
So I tossed the rest out the back door. I figured its pretty wet outside - so eventually they would dissolve.
Of course, since that time we have had one snow after another and we've not seen bare ground in several weeks.
Ah, but Spring nears and yesterday, we had a huge melt.
