If you are into physics… Wait… don’t leave…
This is the coolest site ever and I mean EVER…
You get to make your own machines to play a deceitfully simple game… to put objects on a determined area.
Physics teachers pay attention! You can teach:
Mechanics, fluids, free fall, ballistics ALL IN ONE SITE www.fantasticcontraption.com
You can build vehicles, catapults, simple machines… what have you.
Here’s one I’ve created http://FantasticContraption.com/?designId=2429807 (not state of the art but hey, it’s effective.)
Have fun!
