Ice Spike

Never stop wondering…

This scientist came to me before school and asked how a spike appeared in the ice that she left outside.

“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.” University of Toronto Physics
