Root crops and moon rocks

Two unrelated things: First, I was surprised that people have suffered botulism posioning from fried onions and baked potatoes. The common cause is naturally occuring bacteria in the soil that then multiplies in an oxygen-poor environment: onions slathered in margarine and foil-wrapped potatoes. Amazing. And don't eat green parts of potatoes either :)

Second, I like moon rocks as much as the next guy, but some of this seems a little strange:

• Countries keep losing their goodwill moonrocks (from 2004) or misidentifying petrified wood as their country's goodwill rock (isn't this obvious to anyone who's seen petrified wood?). Good to know they'll be sticking with the paintings

  The Rijksmuseum, which is perhaps better known for paintings by artists such as Rembrandt, says it will keep the piece as a curiosity.

• sending a moon rock to the International Space Station? Does that make sense? The plastic holder/display thing looks good,
• and I was going to buy this, it's only $35k, but they don't take paypal so forget it :) I might have to settle for Apollo 17 surface-flown film.
