Help Kids, Win Chad's Book

Chad is participating in a fundraiser for DonorsChoose, and will give away one copy of his forthcoming book How to Teach Physics to Your Dog to the highest donor, and at least one book to a donor chosen at random (you can also get your question answered on his blog for $20). Check out the classroom projects he's raising money for and then, as it says on his blog, forward your confirmation e-mail to orzelc@steelypips.org to enter for the prizes.
