What can be done with the filter cartridge from the filter

There are rope cartridges for water filters, if you use them do not throw them away. Each cartridge has about 50 meters of strong enough rope, which is always useful on the farm.

In order to “get” the rope, you can use a simple device made of polypropylene pipes and a long hairpin. In fact, the craft is a kind of coil on which a cord can be wound with a screwdriver.

For convenience, the handle at the reel is made to rotate on a hairpin, so after the rope has moved from the cartridge it is convenient to unwind it manually without the aid of a screwdriver.
