a product I designed
This one is kinda wierd.I helped design a coal mining bolt that helps save miners lives but means they can go farther and farther digging coal.
Kind of a mixed blessing.

1. I saw those things installed on a strange TV reality program about a coal mine
The bolts are cool, but the machine that bores the holes and installs them was what really held my interest.
