Do you still have a jack-o'-lantern on your porch? (We do, because this year's cold snap meant it froze instead of mouldering right away.) If so, you may want to check out the book "Rotten Pumpkin." This picture book shows us what happens to the pumpkin after Halloween, with mice, slugs, medicinal mold, and other forces of nature. A kid who likes candy experiments might just be the kind of kid who will look at this book and say "Cool!" instead of "Gross!"
