For my science project, need about 3 feet of copper wire...approx how much will that cost me? I want the wires to be pretty thin :)
no. romex, household wiring, can be as little as $0.57/ft and i bett you don't really need 3 wire, 8 gauge romex for your project...
Copper wire is probably the most expensive, but you only need 3 feet of it. Best to buy it by the foot and not by the reel. Home Depot has it. Or you can find it online (OKorder for example) as scrap wire but then you've got wait time, shipping, etc. If you know the gauge (thickness) you need, Home Depot will tell you on the phone how much it would be for 3 ft.
