Just what I'd love to have in my backyard, a "Blasttube"

I imagine if that were in my backyard, I'd aim it at my neighbor's barky dogs & have it bark-actuated. One problem solved, several others created.

Ha! That's the most ingenious use of a tumblweed I've seen. A late friend of mine was security chief there at Sandia for a couple decades, said it was an awesome place to work with all that goes on there.
