Jim Kelley  asked the Naked Scientists:

Hello!

I've recently discovered your podcast and have enjoyed it  immensely.  I have a question for you regarding something I saw happen recently in my freezer.  I filled an ice tray with water and put it in  the freezer, a few hours later I went to get some ice out of another  ice tray and saw that the ice tray I filled earlier had one cube with  a 'spike' of ice growing out of it kind of like a stalagmite.  What could've caused this?

thanks!

Jim

What do you think?
