Is a panicked birthday party really that big of a deal though?

Watched a guy try that once and ended up with a mouthful of muddy water when the hose slipped.

Man, that Oklahoma shop story gives me chills. In my experience, when the silicate settles out you get that weird crystal formation that just chews through soft metals like butter. I'd highly recommend shaking the hell out of any new coolant jugs before you pour them in, just to make sure everything is mixed back up. Also, if you ever see a batch that looks kinda cloudy or has stuff floating in it, don't even risk it, just send it back.
