Re: [Texascavers] Glow in the Dark Rope for caving?
Someone had some of that glow-in-the-dark rope from Harbor Freight out at the Kerrville Folk Festival last year. It looked great for the first few days, but then basically stopped glowing much at all. It was outside exposed to the sun being used to hold down tents and shade canopies. Dale

[Texascavers] Glow in the Dark Rope for caving?
Some of you probably have seen this before, but I had not until a Memorial Day visit to Harbor Freight Tools. This 100% polypropylene rope includes fluorescent material that can be charged with either natural or artificial light and will then glow for up to 5 hours when placed in the dark. Fluorescent material can be re-charged as often as needed for up to 6 months. Perfect for backyard trip hazards, caves, underwater, tent tie-downs, and campground perimeter markers. Diamond-braid minimizes stretch for long life and durability. Resistant to abrasion, gas-oil, mildew, and chemicals. 3/16 x 50 ft for $2.99; 70 lb safe working load 1/4 x 50 ft for $3.99. 90 lb safe working load Not recommended for cavers over 70 to 90 lbs, or for pits over 50 ft deep. One advantage is being able to see where the rope ends. LowGun ;-)

Re: [Texascavers] Glow in the Dark Rope for caving?
There's a reason cavers do not use polypropylene rope (basically water-ski rope). It has low strength and low abrasion resistance relative to nylon or polyester. (It does float, however, which can be valuable in river caves.) The fluorescent property is not inherent in polypropylene, though, so presumably other types of rope could also be made to glow in the dark. Still, it would be of minimal utility. If a caving trip lasted more than 6 hours (likely), then the rope would no longer be glowing by the time a team got back to it (or used it in the first place).

Re: [Texascavers] Glow in the Dark Rope for caving?
There is a technology for making theluminescence last longer, such that you don't have to continually stimulate it with bright light. You could mix in some radioactive material, such as tritium or radium, as was done for many luminous dial watches and other instruments.http://elginwatches.org/help/luminous_dials.htmlJust think, as it rubbed off of yourradioluminescent rope onto you, then you, too, could glow in the dark without having to be flashed every 6 hours. Of course, they might have to add a few items to the warning label.;-)Rod-Original Message-From: Mark Minton Sent: Jun 2, 2011 9:30 PMTo: lmcn...@austin.rr.com, Texas Cavers Subject: Re: [Texascavers] Glow in the Dark Rope for caving?
