I have incorporated more common materials into this project, so this version is more accessible to people like me who don't want to go out and buy alligator clips and such things.
Hover your mouse on the yellow squares for tool uses. You might be able to use something else instead.
LARGE WOOD PLATFORM, approx. 1.25 feet by 1 foot
2 COAT HANGERS
2 CLOTHES PINS
TAPE, preferably electrician's
4 SCREWS, I don't recommend using nails
SCREWDRIVER or DRILL
Step 1: Screw in the Screws
Step 2: Bend off the Wire
Step 3: Make a Small Loop
Step 4: Place Wire Under Screws
Step 6: Clothes Pin Stuff
Then I taped down the top of the spring. The spring moves around a lot so I highly suggest doing this, no matter how much of a pain it might be. I then taped it in several places to keep the spring on even better and keep the clothes pin closed tight.
