Exploring Flooded Brewery Cave With Homemade ROV

Previously I built a small remotely-operated submarine for underwater exploring. In this episode we're testing it out in a local brewery cellar. St. Paul has a lot of artificial sandstone "caves" that were carved out back in the late 1800s for cold storage. This particular tunnel is one of the oldest, and has a small lake inside fed by natural springs.

If you'd like to see more sandstone caves and tunnels, we're digging our own in Wisconsin! See more about that here: https://youtu.be/XgINZBG3NgU
