Genius!

I know I've bragged before about Jacob and how amazed I am at his talent of constructing things. But this just beats them all. He's been wanting this rollercoaster K'nex set for quite some time so we finally got it for him for Christmas. It looked rather intimidating to me when he dumped out all the pieces and started in on the thick instruction guide. But he didn't even bat an eye at it. This kid put this thing together BY HIMSELF in a couple of days. Seriously amazing! You should enlarge the picture to see how intricate it is.
