In this video I show how to make a sandblaster and use it to dig fossils out of rock.This project was quick and easy, and can be scaled up using larger tubing for a full size sandblaster.

The small brass tubing used in the video was 3/32″ (2.38mm) in diameter, which was about perfect for baking soda or sand as blasting media.Watch the video from NightHawkInLight for more info.
