Retired rope uses

Alright, I'm certain that this thread exists elsewhere, but I can't seem to find it. (If you can, send me the link).

I recently found myself with a 50m rope with 2 core-shots on it. I want to know if you guys have some USEFUL repurposes for ropes! I've seen things like rugs or whatever but I'd prefer to repurpose it for something really useful... Any suggestions??

Rope swing. You can make them longer and higher and if you cut it at the core shot you can jump with some slack in the swing

Donate to newbies for knots practice, cut the core-shots out first. 

Cut out the core shots. Shorter lengths of climbing rope are useful for building toprope anchors or keeping in your car for towing stuff.

I recently supplied a bunch of rope pieces which had been retired from route development for a rope fence. Short sections are useful for fixed lines on approaches. If you have boating friends, climbing makes good dock lines.
