I suppose I should close out the Desert Bus saga. Over 6 days, 11 hours, the Desert Bus crew managed to raise $521,500 for Child's Play, which is a record for them by a gigantic margin. But that isn't what I'd really like to pass along.
Through the course of the run, the Desert Bus chat room had, among other assorted ridiculousness, been getting inordinately excited over silica gel. Towards the end, as a gag, the crew decided, oh, why not, we'll put a silica gel packet up for auction just to see what happens. Maybe we'll make a couple bucks.
What happened? 'Notch', aka Markus Persson, creator of Minecraft, was what happened.
Oh, by the way, one thing to keep in mind: silica gel naturally goes for roundabout $3-5 per kilogram.
