Birth Skeleton with hard center?

[GreenDK]

Hi all.

I am trying to figure out how Birth Skeleton works.
Thanks to the nice people on FB it's going ok.
But I have two questions.

1. How can I make the round center of my object hard, so it does not deform on impact?
2. How do I make a flow with the Birth Skeleton object? (Like a bunch of them falling)

Thank you.
