Science Made Cool writes from Tokyo, describing the world's only parasite museum. Someday I'll get there... Sadly, the keychain with the sushi worm embedded inside is not for sale online... Update: Mark asks whether there's an American museum in Maryland. It's a collection, not a museum. I write about my visit there in Parasite Rex. A wonderfully creepy place, but no parasite-entombing keychains for sale.
