    There is no camera trickery, photoshopping, no hidden pieces of plastic or anything overhanging the birdbath.

    It was just there when we got up this morning !

    Yes, it is called an ice spike which is an upward-facing icicle that forms as a body of water freezes. Water expands when it freezes and if there is already a thin sheet of surface ice over the body of water, further freezing can force water out and upwards through a crack or weak point in the sheet. This can produce a tube-like structure where water emerges at the tip, progressively lengthening the tube. Spike formation stops when the tip freezes and seals.
    The hand of time rested on the half-hour mark, and all along that old front line of the English there came a whistling and a crying. The men of the first wave climbed up the parapets, in tumult, darkness, and the presence of death, and having done with all pleasant things, advanced across No Man's Land to begin the Battle of the Somme. - Poet John Masefield.
