Ants-away for Hummingbird Feeder

Ants on your hummingbird feeder? 

Here's a simple way to keep them off. Very durable, very simple, and very cheap. See disclaimer at bottom

Materials needed:

     (1)-Tuna Can or similar
     (1)-two inch long machine screw
     (2)-nuts to fit machine screw
     (2)-small rubber washers
     (2)-short (about 6 inches long) pieces of copper electric wire

Hints: 

   - CAUTION: wire must be wrapped tight around machine screw to stop slipping, which could break the feeder.
   - Pliers can be used to twist the wire around the machine screw.
   - Stripping insulation from wire probably not needed. I did to make it easier to wrap the wire.
   - The first set of rubber washers I used were much larger and stiffer, and leaked like a sieve. 
   - There's a rubber washer on the inside of the can (not visible)
