Yea, but you do realize it contains the deadly, corrosive substance monohydrogen dioxide, don't you?
The stuff's known as di-hydrous oxide. Then there's this stuff called heavy water. Anyways, get with the program o.k? And yes, if consumed, inhaled, or impacted in sufficient quantities (and speed) it will kill you. Its very bad stuff and should be outlawed.
Where is the government that should be looking out for the little people's best interests? Nowhere. All they do is regulate how much can be flushed at one time.
But we digress. You can't flush ice. Er, well, not a whole lot of it (unless its in a slurry mixture).
