Markers are never a good way to 'mark' your rope. Buy a rope that's already marked with another color. It's in any case better to do it old fashioned and find it using some rope techniques. We use electrical tape on all our equipment. But I cannot guarantee its safety.


How about food coloring? It's very benign since it's for human consumption, no solvents, etc.


Climbing ropes are meant to hold falls, and to absorb the shock of the fall itself through stretching (they can stretch up to 30% of their length during a severe fall so to reduce the impact force on the climber). There's no need for a climbing rope to hold more than it does, because any more force during a fall and the body of the falling climber would be ...


Essentially para cord is stronger, but its less resilient. Climbing ropes do not need to be strong - you die above about 10G (1000kg) force from internal injuries caused by your harness, a braking strain above this is pointless, even if the rope does not break in a fall that generates very high G forces, you die. Anchors have a force, which if exceeded ...


A climbing rope, as in sport-climbing, is also known as a dynamic rope - it stretches when you fall. If you use polypropylene strips and fall 5 metres, even if they are strong enough not to break, the same force acts on your body as if you fell 5 metres onto solid ground. If this weren't a problem, climbers would all be using steel cable which is stronger ...


If your intending to top-rope with it, or unimaginably lead climb on it, then absolutely not... ever. Polypropylene not only has a super low melting point, but the fibres are a really large diameter, which means they are super susceptible to abrasion, i.e. your rope cutting. It lastly won't stretch when loaded, which is all around bad news in climbing! The ...
