They are round, about the size of a quarter, with a hole in the middle, and are made of a thin strong black cardboard type material.

They look like washers.

Could they be an electrical insulator of some type?

Thanks to all for any ideas!

i read the usually YBCO has a high tempereature but YBCO's low temoerature's create great magnatic fields that can reach up to 50 telsa, because tempreture is realated to kinetic energy, ergo, it may conturbute, in the Going Grenn movement, so can it, or not??? and how it is related to resistive magnets, thanks.....

I need to make a rope from 2 single sized bedsheets and a pillowcase. The rope must be strong enough for a 225 lb person to safely decend from a 4 story window to the ground. How many pieces should each bedsheet be torn into in order to make a rope strong enough to hold the person that is decending the rope? I have no room for trial and error. This has to be correct on my first attempt or else the rope will break because it's not strong enough; or the rope will be too short to reach the ground. The rope will only be used once, unless I can figure out a way to get the rope untied from the 4th story window when I'm on the ground.
