According to the technology review, China plans to control the weather, lest any pesky Tibetans oops, I mean rain clouds try to fall on their Olympic parade.

Then, using their two aircraft and an array of twenty artillery and rocket-launch sites around Beijing, the city’s weather engineers will shoot and spray silver iodide and dry ice into incoming clouds that are still far enough away that their rain can be flushed out before they reach the stadium.

I don’t know about you, but this scares the crap out of me. Are there health affects that come along with these “chemical sprays”?
