Grow one in your freezer! Ice spikes happen when surface water freezes, except for a

small hole or crack, where water pushes up thru and freezes into a spike. Spikes 18 feet

tall have been observed in Lake Erie.


Use *distilled water* in your ice cube tray, or try boiling the water and filtering it. This one

grew with plain tap water.   Tried to take better pics, this is as good as I could get.

Sorry I don't get it. Do you have to do anything?

No, this is just one of those "things that happen sometimes" and you can get it to happen with more predictability by freezing distilled water, or in lieu of that, I have had success freezing boiled then twice filtered water. I understand that in some parts of the country, tap water, when frozen, will produce ice spikes and that it sometimes occurs naturally, in lakes, ponds, and puddles.
