Pit yourself against atomic physics in Bond Breaker, a new puzzle game based on real nano-scale science. You start this game in the smallest way possible - as a single proton, without even a single atom to call your own.

Created by TestTubeGames and scientists at the CaSTL research center at UC Irvine, this is truly the most accurate physics engine to date. After all, what other game is correct down to the atomic level? When you make and break molecular bonds, you’ll encounter real forces and real physics. This isn’t just simple stuff, either! You'll learn about... The forces that bind molecules together How lasers can excite atoms Why water sticks together into drops What happens when you heat something up And much, much more. Simply put, this is the most fun you can have without buying your own Scanning Tunneling Microscope!
