Corrected entry: How on earth did Dennis Quaid's ice pick not shatter the glass below him when they were on top of the shopping mall? There wasn't enough ice for it to dig in, as proved by the fact that it wipes clean so easily.

Correction: Actually, if you looked closer, it seemed to me that the icepick's flat edge part (not the pointy end) latched onto a piece of framing between two sheets of the glass that makes up the roof. So, in essence, that's what's holding the ax in place, the edge of that glass framing.
