Bubbles Bubbles let's you create bubbles on your screen with just a touch. Tap for a little bubble or press and hold for a larger bubble (but don't let it get too big or it will burst!). Once bubbles are created they'll float around the screen until they float away or until you pop them. I like running my finger across the screen and creating a whole bunch of bubbles to pop.
Newton's Cradle Just like a real Newton's cradle, you can pull back a ball and see it's effects on the other side. The most fun happens when you try to disrupt the system by pulling back opposing balls mid-swing. You can also use the accelerometer instead of the multi-touch.
Toss It Throw a piece of paper into a trash can. But it's so much more fun than it sounds. The game uses an awesome physics engine and throws in obstacles, like a fan that blows at different speeds, to throw off your trajectory.
