Forward time:-

Lady Scientists keep the bullet somewhere in the lab
Few more persons enter the lab, unfires bullets from the Rock until the last hole
They store the bullets somewhere in the lab & leave
Rock with no holes stay in the lab
-----INVERSION: Somewhere in future a Rock (with no holes) and few Bullets are inverted and moved to the lab----
Backward time:-

A Lady scientist (walking backwards) retrieve a bullet from the lab
