Step 3: Now what? Its wound flat... Sort of...

Picture of Now what?  Its wound flat...  Sort of...
Probably good enough for this simple experiment.

Tape it up with two leads hanging out.

I know the image isnt the sharpest, but we are looking at one lead from the coil. I stripped the end with some sandpaper and then coiled it around a small screwdriver.

Do this or something similar to strip both ends and make a couple of tight loops. This is not critical, it just gives us a point to attch the light bulb without soldering.

for future reference just use a lighter and burn off a half an inch or so

it makes sure the whole contact is clear and its much faster, decent instructable though

I actually tried burning but found I needed to use sandpaper to clean the carbonized enamel from the wire anyway.  This stuff is so small it really is very little effort to clean with sandpaper.
