# Starting two rigid body animations at different points in time

I am animating a rigid body in cycles but I am experiencing problems when it comes to other rigid bodies. As you can see I would to PEN (White one) to drop after the three rings but both of them seem to occur at the same time. Please Help.

Thank you.

• I think it would be better to split your question to two. One for the keyframing and another for the rolling effect. – qwazix Jan 3 '17 at 11:22

Select the pen then go to the frame in which you don't want the pen to fall (presumably frame 1) and uncheck the Dynamic tick in the rigid body menu. Then mouse over the tick and press I.
This adds a key-frame. Then go to the frame where you want it to fall, and check the Dynamic box (so it's on) and press I to add another key-frame. Then the object will have dynamic rigid collision when the key-frame is hit.
