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.

5. Wow. That's impressive! Yes, a mixed blessing, but in a good way.
