Video: Watching dry ice sublimate (turn into gas instead of liquid) still manages to make me feel like a kid again. The kind of kid who is unsure of the difference between science and magic. OK, not quite ... I'm old now and it's impossible to ever look at things so innocently any more. But when I see the carbon dioxide gas immediately escape the frozen dry ice, I can't help but be entranced. Especially when it's shot up close like this.

Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.
