It usually doesn't break unless objects touch each other. space to create a new object, drag to pick up and throw objects. If two objects get stuck to each other, just pull them apart by dragging one away. Edude's laws of broken physics: 1. ALL objects have the same mass, and therefore have the same weight. 2. if two objects are stuck together, then they shall move downward until they hit the purple ground. 3. The faster you move your cursor when throwing an object, the farther it will go.
