White stringy thing on glass?

[Dwight Devore]

This morning I found what looks to be string with small knots tied in it every 1/8" or so stuck to the front glass. It has a irregular pattern.It is about 6" long. The LFS told me it was a worm, but it doesn't move. Could it be some type of snail eggs.Help
