what are some laser experiments that 7th graders can do? ?
The program is 42 minutes and I can't be bothered to watch the whole thing myself. As a climber I probably have those techniques down anyway. And it's unlikely that I'd ever apply them to escape a fire. For heights 10 meters, simply climb down the rope. If that rope happens to be a fire hose, maybe use it for its intended purpose instead. For heights 10 meters, there's never a rope handy when you need one. (It's pretty hard to rappel on a rope made of tied together phone cords and garments.)
you are better off using thread sealant tape or dope. not expensive. however, if you are using a compression fitting directly on the galvanized pipe, nothing will ever work. totally wrong application. some type of thread adapter fitting has to go on first.
