I'm sure many here would like to share this with their kids, and all the other kids they know . "crayon physics deluxe" is the name, enjoy the rocket zooming to the tower's peak amazing it's like in some dream haha http://www.youtube.com/watch?v=yGpMu0NIOFY&feature=related And i also wanna add the software called "Phun" it is a physics based program where u create stuff with the goal of understanding and interpreting physics, very entertaining if you like to get down with brains. http://www.phunland.com/wiki/Home. remember u can buy both programs and play it on your computer, cheap, fun, educational, what adult wouldnt find it exiting to show this to the little humans
