Gravity Chain
This chain and wreaking ball are in an animation where the gravity has effect on the object (I call this animation when it animates itself) via adding a rigid body to the fool cubes and chain. You have to though make the floor passive so it won't move, you also have to make the cubes and chain active so the can move freely.
Soft Body Physics
These spheres instead of being solid like the chains are made soft and flexible and can be deformed when fallen upon a surface or object. I started by adding collisions to the non-moving objects then adding a soft body to the spheres then adjusting them so they will act like a squishy ball.
Water Physics
This liquid here pouring from the hose is another physics animation. Here the water is able to fill the cup and overflow a little. this is because I had to burn the result (which means it dose its thing and then afterwards you can't change what happens) so the computer didn't crash. I took a sphere and added a quick liquid so I could flow. Then I made the cup so it could fill it. More can be found on the Youtube video.
Marble Run
This marble run was made in a similar way that the Gravity chain was made with rigid bodies with passive and active. (more info about it on the Gravity Chain page) I made a tube from a line from a cube (more can be found on the video) and made it into a cube then making it a passive rigid body and making it so things can go through it. Then I took a sphere an put a rigid body on that to make it passive than I extended the Tube until I got around 700 Frames and then I made a little marble catch box.
