Unable to explode object I haven't been able to get the fragments of the green object to explode.  I'm not sure why, since I added physics, rigid bodies and made it active.  

Here's a screenshot:



Here is the .blend:
Your object that you want to explode is one solid object. In order for it to explode you must first break it up into pieces.

I took the following steps:


Edit mode >Remove doubles
Object mode run cell fracture
Move object on layer one to a secondary/ unused layer and
move fractures to layer one
Add active rigid body physics to all fractures with collision margin
enabled at 1





Bake simulation then play the animation
