Step 1: Gathering Materials

you will need:

2 thick rubber bands.
A magnet.
2 jumbo paper clips.
small dowel rod 3/4" diameter.
sandpaper, medium grit.
connecting wire.
wire strippers.
24 gauge magnet wire, about 50".
D-cell battery.
packing foam about 2X2" and 3/4" deep.
stiff piece of straw about 2" long.

Step 2: Making the Coil

First wind the magnet wire tightly around the dowel leaving about 2" excess on each end.
remove the dowel, you should have a spring-like coil.(see pics)

Step 3:

Now sand the top half of each end well. (it should shine)
do not sand the bottom half!
Then take the magnet and the packing foam and lay the magnet on top.
Now take your jumbo paper clips and unfold each one.(see pics)
then stick the paper clips halfway into the packing foam.
