Donald Henry discovered an "ice spike" at his home on Camelot Street. Ice spikes are a rare phenomena. According to the department of physics form the University of Toronto, ice spikes form because as the ice freezes fast under supercooled conditions, the surface can get covered except for a small hole. Water expands when it freezes. As freezing continues, the expanding ice under the surface forces the remaining water up through the hole and it freezes around the edge forming a hollow spike. Eventually, the whole thing freezes and the spike is left. (Photo by Lashana Harney)
