Really? I thought he understood the question. By throwing the shoe, he pushed himself ever so slightly in the other direction. Being on a frictionless surface, he would glide to the edge of the pond opposite of the direction he threw the shoe.
Flash-Block is the only thing that saves this machine, but whether it's a Flash or a Firefox-Flash issue, I'm not sure.
I remember a similar situation with Virginia's scratch-off lottery tickets: a fixed number of tickets are printed with winning numbers, and once those prizes are all claimed, the Lottery Agency is supposed to pull the remaining tickets since they're all losers. But of course, they don't.
What part of the story of the family in a decrepit Lexus with worn-out brakes doing acceleration overtime wasn't true? THAT's what got this Toyota-bashing story started. And even Toyoda himself admitted it - they got greedy and too big too fast.
Only problem I foresee is that with a 4" telescope, unless there's some kind of tracking mechanism, regardless of what you're looking at, cycling through a bunch of kids will be difficult as the object/detail in question will have moved and the telescope will need to be constantly re-pointed. THAT will be the toughest part in my opinion. You can reduce the problem by paying close attention to the pivoting mechanisms on the telescope (possibly with some dry runs without the kids) so that the one axis points to celestial north and the other along the celestial plane. If you're tracking the moon or Jupiter, then a turn of only one of the knobs (this thing does have a tracking mechanism, right?) will keep it in the scope.
