translation.en: I'm sure it's obvious to you now, but it was actually yesterday that I was reminded of why. I was having a conversation with Steve Jurvetson, over downstairs by the escalators, and he was telling me that when Chris sent out that little box, one of the items in it was the hydrophobic sand -- the sand that doesn't get wet. He said that he was playing with it with his son.
