Hmm: Does frozen water do the same in space?

Why doesn’t it do it on earth? Is it the air in the way?

ice cubes stick to other ice cubes, I would assume it's because of melting and refreezing but I can see one reason why cold welding might not happen: Ice is dihydrogen oxide, so that oxygen atom might be a problem for cold welding.

Dunno, but I've heard that tongues can weld themselves to icicles on Earth.

Your applying a liquid (water in your tongue) to an object at the freezing point of that water. The water is freezing onto the surface of the ice.

I don't think this is cold welding but I could be wrong.

Some of us even experienced it in person. :)
